Prologue
Welcome
Welcome to Geing Started with Ubuntu, an introductory guide wrien to
help new users get started with Ubuntu.
Our goal is to cover the basics of Ubuntu (such as installation and work-
ing with the desktop) as well as hardware and soware management, work-
ing with the command line, and security. We designed this guide to be
simple to follow, with step-by-step instructions and plenty of screenshots,
allowing you to discover the potential of your new Ubuntu system.
Canonical releases new versions of Ubuntu every six months; every
fourth release is a so-called long-term support () version. Each Ubuntu
release has a version number that consists of the year and month number
of the release, and an alliterative code name using an adjective and an
animal. Code names are in consecutive alphabetic order, allowing a quick
determination of which release is newer. Ubuntu . (code-named Saucy
Salamander) is considered a regular release and is supported by Canonical
with patches and upgrades for nine months. e most recent  version is
Ubuntu . (Precise Pangolin), and has support for five years (until April
). Whenever a new version of Ubuntu is released, we will incorporate
updates and changes into our guide, and make a new version available at
http://www.ubuntu-manual.org.
Geing Started with Ubuntu . is not intended to be a comprehensive
Ubuntu instruction manual. It is a quick-start guide that will get you do-
ing the things you need to do with your computer easily, without geing
bogged down with technical details. Ubuntu . incorporates many new
and improved features, including new icons (some dynamic), more appear-
ance options, locally integrated menus, and smart scopes, to name just a
few. With the help of this guide, it should not take long before new users
get used to the Unity desktop environment. Unity includes the Starter, the
Dash, the , indicators, and an on-screen display notification system
(). All these features will be explained in this guide.
For more detailed information on any aspect of the Ubuntu desktop, see
the “Ubuntu Desktop Guide,” which can be obtained in any of the following
ways:
‣ in the Dash, type help.
‣ in the indicator area, click Session indicator ‣ Ubuntu Help.
‣ go to https://help.ubuntu.com, Ubuntu . ‣ Ubuntu Desktop Help.
ere are also many excellent resources available on the Internet. For
example, on https://help.ubuntu.com you will find documentation on in-
stalling and using Ubuntu. At the Ubuntu Forums (http://ubuntuforums.org)
and Ask Ubuntu (http://askubuntu.com), you will find answers to many
Ubuntu-related questions. You can find more information about Ubuntu’s
online and system documentation in Chapter 8:
Learning More.
If something isn’t covered in this manual, chances are you will find the
information you are looking for in one of those locations. We will try our
best to include links to more detailed help wherever we can.

Ubuntu Philosophy
e term “Ubuntu” is a traditional African concept originating from the
Bantu languages of southern Africa. It can be described as a way of con- People sometimes wonder how to pronounce
Ubuntu. Each u is pronounced the same as in
the word put except for the last u which is
pronounced the same as in the word due.
necting with others—living in a global community where your actions
affect all of humanity. Ubuntu is more than just an operating system: it is
a community of people coming together voluntarily to collaborate on an
international soware project that aims to deliver the best possible user
experience.
The Ubuntu Promise
‣ Ubuntu will always be free of charge, along with its regular enterprise
releases and security updates.
‣ Ubuntu comes with full commercial support from Canonical and hun-
dreds of companies from across the world.
‣ Ubuntu provides the best translations and accessibility features that the
free soware community has to offer.
‣ Ubuntu’s core applications are all free and open source. We want you to
use free and open source soware, improve it, and pass it on.
A brief history of Ubuntu
Ubuntu was conceived in  by Mark Shuleworth, a successful South
African entrepreneur, and his company Canonical. Shuleworth recognized To learn more about Canonical, go to http://
www.canonical.com.the power of Linux and open source, but was also aware of weaknesses that
prevented mainstream use.
Shuleworth set out with clear intentions to address these weaknesses
and create a system that was easy to use, completely free (see Chapter :
Learning More for the complete definition of “free”), and could compete
with other mainstream operating systems. With the Debian system as a
base, Shuleworth began to build Ubuntu. Using his own funds at first, Debian is the Linux operating system that
Ubuntu is based upon. For more information
visit http://www.debian.org/.
installation s were pressed and shipped worldwide at no cost to the
recipients. Ubuntu spread quickly, its community grew rapidly, and soon
Ubuntu became the most popular Linux distribution available.
With more people working on the project than ever before, its core
features and hardware support continue to improve, and Ubuntu has gained
the aention of large organizations worldwide.
While large organizations oen find it useful to pay for support services, For information on Ubuntu Server Edition, and
how you can use it in your company, visit http://
www.ubuntu.com/business/server/overview.
Shuleworth has promised that the Ubuntu desktop operating system
will always be free. Ubuntu is installed on an estimated % of the world’s
computers. is equates to tens of millions of users worldwide, and is
growing each year. As there is no compulsory registration, the percentage
of Ubuntu users should be treated as an estimate.
What is Linux?
Ubuntu is built on the foundation of Linux, which is a member of the Unix
family. Unix is one of the oldest types of operating systems, and together
with Linux has provided reliability and security for professional applica-
tions for almost half a century. Many servers around the world that store
data for popular websites (such as YouTube and Google) run some variant
of Linux or Unix. e popular Android system for smartphones is a Linux
variant; modern in-car computers usually run on Linux. Even the Mac  

 
is based on Unix. e Linux kernel is best described as the core—almost the
brain—of the Ubuntu operating system.
e Linux kernel is the controller of the operating system; it is responsi-
ble for allocating memory and processor time. It can also be thought of as
the program which manages any and all applications on the computer itself.
While modern graphical desktop environments have generally replaced
early command line interfaces, the command line can still be a quick and
efficient way of performing many tasks. See Chapter : Advanced Topics
for more information, and Chapter : e Ubuntu Desktop to learn more
about  and other desktop environments.
Linux was designed from the ground up with security and hardware
compatibility in mind, and is currently one of the most popular Unix-based
operating systems. One of the benefits of Linux is that it is incredibly flex-
ible and can be configured to run on almost any device—from the smallest
micro-computers and cellphones to the largest super-computers. Unix was
entirely command line-based until graphical user interfaces (s) emerged
in  (in comparison, Apple came out with Mac  ten years later, and
Microso released Windows . in ).
e early s were difficult to configure, clunky, and generally only
used by seasoned computer programmers. In the past decade, however,
graphical user interfaces have grown in usability, reliability, and appear-
ance. Ubuntu is just one of many different Linux distributions. To learn more about Linux distributions, see
Chapter 8: Learning More.
Is Ubuntu right for you?
New users to Ubuntu may find that it takes some time to feel comfort-
able when trying a new operating system. You will no doubt notice many
similarities to both Microso Windows and Mac   as well as some dif-
ferences. Users coming from Mac   are more likely to notice similarities
due to the fact that both Mac   and Ubuntu originated from Unix. e
Unity shell, which is the default in Ubuntu, is a completely new concept,
which needs some exploring to get used to it. See Chapter : e Ubuntu
Desktop for more information about the Unity shell.
Before you decide whether or not Ubuntu is right for you, we suggest
giving yourself some time to grow accustomed to the way things are done
in Ubuntu. You should expect to find that some things are different from
what you are used to. We also suggest taking the following into account:
Ubuntu is community based. at is, Ubuntu is developed, wrien, and
maintained by the community. Because of this, support is probably
not available at your local computer store. Fortunately, the Ubuntu
community is here to help. ere are many articles, guides, and manuals
available, as well as users on various Internet forums and Internet Relay
Chat () rooms that are willing to assist beginners. Additionally, near
the end of this guide, we include a troubleshooting chapter: Chapter :
Troubleshooting.
Many applications designed for Microso Windows or Mac   will not run
on Ubuntu. For the vast majority of everyday computing tasks, you
will find suitable alternative applications available in Ubuntu. However,
many professional applications (such as the Adobe Creative Suite) are
not developed to work with Ubuntu. If you rely on commercial soware
that is not compatible with Ubuntu, yet still want to give Ubuntu a try,
you may want to consider dual-booting. Alternatively, some applications To learn more about dual-booting (running
Ubuntu side-by-side with another operating
system), see Chapter 1: Installation.

developed for Windows will work in Ubuntu with a program called
Wine. For more information on Wine, see Chapter : Advanced Topics.
Many commercial games will not run on Ubuntu. If you are a heavy gamer,
then Ubuntu may not be for you. Game developers usually design games
for the largest market. Since Ubuntu’s market share is not as substantial
as Microso’s Windows or Apple’s Mac  , fewer game developers
allocate resources towards making their games compatible with Linux. If See Chapter 5: Software Management to learn
more about Ubuntu Software Center.you just enjoy a game every now and then, there are many high quality
games that can be easily installed through the Ubuntu Soware Center.

1 Installation
Getting Ubuntu
Before you can get started with Ubuntu, you will need to obtain a copy of Many companies (such as Dell and System76)

you already have Ubuntu installed on your
computer, feel free to skip to Chapter 2: The

the Ubuntu installation image for  or . Some options for doing this
are outlined below.
Minimum system requirements
If you are unsure whether it will work on your computer, the Live  is a
great way to test things out first. Below is a list of hardware specifications
that your computer should meet as a minimum requirement.
‣  GHz x processor (Pentium  or beer)
‣   of system memory ()
‣   of disk space (at least   is recommended)
‣ Video support capable of × resolution
‣ Audio support
‣ An Internet connection (highly recommended, but not required)
Downloading Ubuntu
e easiest and most common method for geing Ubuntu is to download
the Ubuntu  image directly from http://www.ubuntu.com/download.
Choose how you will install Ubuntu:
‣ Download and install
‣ Try it from a  or  stick
Download and Install / Try it from a DVD or USB stick
For the Download and install, or Try it from a  or  stick options, select
whether you require the -bit or -bit version (-bit is recommended for
most users), then click “Start download.”
32-bit versus 64-bit
Ubuntu and its derivatives are available in two versions: -bit and -bit.
is difference refers to the way computers process information. Comput- 32-bit and 64-bit are types of processor
architectures. Most new desktop computers
have a 64-bit capable processor.
ers capable of running -bit soware are able to process more information
than computers running -bit soware; however, -bit systems require
more memory in order to do this. Nevertheless, these computers gain per-
formance enhancements by running -bit soware.
‣ If your computer has a -bit processor, install the -bit version.
‣ If your computer is older, a netbook, or you do not know the type of
processor in the computer, install the -bit version.
If your computer has a -bit processor, select the “-bit” option before
you click “Start download.”

Downloading Ubuntu as a torrent
When a new version of Ubuntu is released, the download servers can get Torrents are a way of sharing files and informa-
tion around the Internet via peer-to-peer file
sharing. A file with the .torrent extension is
made available to users, which is then opened
with a compatible program such as uTorrent,
Deluge, or Transmission. These programs
download parts of the file from other people all
around the world.
“clogged” as large numbers of people try to download or upgrade Ubuntu
at the same time. If you are familiar with using torrents, you can download
the torrent file by clicking “Alternative downloads,” and then “BitTorrent
download.” Downloading via torrent may improve your download speed,
and will also help to spread Ubuntu to other users worldwide.
Burning the DVD image
Once your download is complete, you will be le with a file called ubuntu- While the 64-bit version of Ubuntu is referred
to as the “AMD64” version, it will work on Intel,
AMD, and other compatible 64-bit processors.
.-desktop-i.iso or similar (i here in the filename refers to the -bit
version. If you downloaded the -bit version, the filename contains amd
instead). is file is a  image—a snapshot of the contents of a —
which you will need to burn to a .
Creating a bootable USB drive
If your  is able to boot from a  stick, you may prefer to use a 
memory stick instead of burning a . Scroll down to “Burn your 
or create a  drive,” select  or  stick, choose the  you are using
to create the  drive, and then click Show me how. If you select the “
Stick” option, your installation will be running from the  memory stick.
In this case, references to Live , will refer to the  memory stick.
Trying out Ubuntu
e Ubuntu  and  stick function not only as installation media, but
also allow you to test Ubuntu without making any permanent changes to
your computer by running the entire operating system from the  or 
stick.
Your computer reads information from a  at a much slower speed In some cases, your computer will not recognize
that the Ubuntu DVD or USB is present as it
starts up and will start your existing operating
system instead. To run Ubuntu from the Live
DVD or USB, we want the computer to look
for information from the Live DVD or USB
first. Changing your boot priority is usually
handled by BIOS settings; this is beyond the
scope of this guide. If you need assistance with
changing the boot priority, see your computer
manufacturer’s documentation for more
information.
than it can read information off of a hard drive. Running Ubuntu from
the Live  also occupies a large portion of your computer’s memory,
which would usually be available for applications to access when Ubuntu is
running from your hard drive. e Live / experience will therefore
feel slightly slower than it does when Ubuntu is actually installed on your
computer. Running Ubuntu from the / is a great way to test things
out and allows you to try the default applications, browse the Internet, and
get a general feel for the operating system. It’s also useful for checking that
your computer hardware works properly in Ubuntu and that there are no
major compatibility issues.
To try out Ubuntu using the Live / stick, insert the Ubuntu 
into your  drive, or connect the  drive and restart your computer.
Aer your computer finds the Live / stick, and a quick load-
ing screen, you will be presented with the “Welcome” screen. Using your
mouse, select your language from the list on the le, then click the buon
labelled Try Ubuntu. Ubuntu will then start up, running directly from the
Live / drive.
Once Ubuntu is up and running, you will see the default desktop. We
will talk more about how to actually use Ubuntu in Chapter : e Ubuntu
Desktop, but for now, feel free to test things out. Open some applications,
change seings and generally explore—any changes you make will not be

the “Power” buon in the top right corner of your screen (a circle with
a line through the top) and then select Restart. Follow the prompts that
appear on screen, including removing the Live  and pressing Enter
when instructed, and then your computer will restart. As long as the Live

load Ubuntu from the . When you first start from the , you will
be presented with a screen asking you whether you want to first try out
Ubuntu or install it. Select the language you want to view the installer
in and click on the Install Ubuntu buon. is will start the installation
process.
If you have an Internet connection, the installer will ask you if you

e “Preparing to install Ubuntu” screen will also let you know if you
have enough disk space and if you are connected to a power source (in case
you are installing Ubuntu on a laptop running on baery). Once you have

have an empty hard drive, as Ubuntu will automatically create the neces-
sary partitions for you.
Formaing a partition will destroy any data currently on the partition.
Be sure to back up any data you want to save before formaing. More
information and detailed instructions on partitioning are available at:

To reduce the time required for installation, Ubuntu will continue the
installation process in the background while you configure important user
details—like your username, password, keyboard seings and default time-
zone.
Where are you?
Figure 1.5: Tell Ubuntu your location.
e next screen will display a world map. Using your mouse, click your
geographic location on the map to tell Ubuntu where you are. Alternatively,
you can type your location in the field below the map. is allows Ubuntu
to configure your system clock and other location-based features. Click
Continue when you are ready to move on.
Keyboard layout

Next, you need to tell Ubuntu what kind of keyboard you are using.
In most cases, you will find the suggested option satisfactory. If you are
unsure which keyboard option to select, you can click the Detect Keyboard

Who are you?
Ubuntu needs to know some information about you so it can set up the
primary user account on your computer. When configured, your name will
appear on the login screen as well as the user menu, which we discuss in
Chapter : e Ubuntu Desktop.
On this screen you will need to tell Ubuntu:
‣ your name
‣ what you want to call your computer
‣ your desired username
‣ your desired password
‣ how you want Ubuntu to log you in
Figure 1.7: Setup your user account.
Enter your full name under Your name. e next text field is the name
your computer uses, for terminals and networks. You can change this to
what you want, or keep the predetermined name. Next is your username,
the name that is used for the user menu, your home folder, and behind the
scenes. You will see this is automatically filled in for you with your first
name. Most people find it easiest to stick with this. However, it can be
changed if you prefer.
Next, choose a password and enter it into both password fields. When
both passwords match, a strength rating will appear to the right that will
show you whether your password is “too short,” “weak,” “fair,” or “strong.”
You will be able to continue the installation process regardless of your
password strength, but for security reasons it is best to choose a strong
one. is is best achieved by having a password that is at least six char-
acters long, and is a mixture of leers, numbers, symbols, and upper-
case/lowercase. Avoid obvious passwords that include your birth date,
spouse’s name, or the name of your pet.
One account to log in to everything on Ubuntu
During the installation you have the possibility to log in into your existing
Ubuntu One account or to create a new one. Fill in all the needed informa-
tion such as your email address and password and click Continue.

Login Options
Finally, at the boom of this screen you have two options regarding how
you wish to log in to Ubuntu. You may also choose to have Ubuntu encrypt
your home folder.
‣ Log in automatically
‣ Require my password to log in
– Encrypt my home folder
Log in automatically
Ubuntu will log in to your primary account automatically when you start
up the computer so you won’t have to enter your username and password.
is makes your login experience quicker and more convenient, but if
privacy or security are important to you, we don’t recommend this option.
Anyone who can physically access your computer will be able to turn it on
and also access your files.
Require my password to login
is option is selected by default, as it will prevent unauthorized people
from accessing your computer without knowing the password you cre-
ated earlier. is is a good option for those who, for example, share their
computer with other family members. Once the installation process has
been completed, an additional login account can be created for each family
member. Each person will then have their own login name and password,
account preferences, Internet bookmarks, and personal storage space.
Encrypt my home folder
is option provides you with an added layer of security. Your home folder
is where your personal files are stored. By selecting this option, Ubuntu
will automatically enable encryption on your home folder, meaning that
files and folders must be decrypted using your password before they can
be accessed. erefore if someone had physical access to your hard drive

 
(for example, if your computer was stolen and the hard drive removed), they
would not be able to see your files without knowing your password.
If you choose this option, be careful not to enable automatic login at a later date.
It will cause complications with your encrypted home folder, and will potentially
lock you out of important files.
Finishing Installation
Ubuntu will now finish installing on your hard drive. As the installation
progresses, a slideshow will give you an introduction to some of the default
applications included with Ubuntu. ese applications are covered in more
detail in Chapter : Working with Ubuntu. e slideshow will also highlight

2 The Ubuntu Desktop
Understanding the Ubuntu desktop
Initially, you may notice many similarities between Ubuntu and other
operating systems, such as Microso Windows or Mac  . is is because
they are all based on the concept of a graphical user interface ()—i.e.,
you use your mouse to navigate the desktop, open applications, move ﬁles,
and perform most other tasks. In short, things are visually-oriented. is
chapter is designed to help you become familiar with various applications
and menus in Ubuntu so that you become conﬁdent in using the Ubuntu
.
Figure 2.1: The Ubuntu 13.10 default desktop.
Unity
All -based operating systems use a desktop environment. Desktop envi-
ronments encompass many things, including (but not limited to):
‣ e look and feel of your system
‣ e way the desktop is laid out
‣ How the desktop is navigated by the user
In Linux distributions (such as Ubuntu), a number of desktop environ- To read more about other variants of Ubuntu,

Aer installing and logging in to Ubuntu, you will see the Unity desktop.
is initial view is comprised of the desktop background and two bars—a
horizontal one located at the top of your desktop called the menu bar and a
vertically-oriented bar at the far le called the Launcher.

     .
The Desktop Background
Below the menu bar at the top of the screen is an image covering the entire
desktop. is is the default desktop background, or wallpaper, belonging to
the default Ubuntu . theme known as Ambiance. To learn more about
customizing your desktop (including changing your background), see the
section on Customizing your desktop below.
The Menu Bar
e menu bar incorporates common functions used in Ubuntu. e icons on
the far-right of the menu bar are located in an area of the menu bar called
the indicator area, or notification area. Each installation of Ubuntu may
contain slightly different types and quantities of icons based on a number of
factors, including the type of hardware and available on-board peripherals
upon which the Ubuntu installation is based. Some programs add an icon to
the indicator area automatically during installation (e.g., Ubuntu One). e
most common indicators are: For more about:
‣ the Ubuntu One indicator see Ubuntu One
on page 76;
‣ the Messaging indicator see Using instant
messaging on page 60;
‣ the Network indicator see Getting online on
page 39;
‣ the Session indicator see Session options on
page 34.
Keyboard indicator ( ) allows you to select a keyboard layout, if more
than one keyboard layout is chosen. e keyboard indicator menu
contains the following menu items: Character Map, Keyboard layout
Chart, and Text Entry Seings.
Network indicator ( ) manages network connections, allowing you to
connect quickly and easily to a wired or wireless network.
Ubuntu One indicator ( ) allows you to backup files online and share files
with your friends, family, and coworkers.
Messaging indicator ( ) incorporates your social applications. From here,
among others, you can access instant messenger and email clients.
Sound indicator ( ) provides an easy way to adjust the sound volume as
well as access your music player and sound seings.
Clock displays the current time and provides a link to your calendar and
time and date seings.
Session indicator ( ) is a link to the system seings, Ubuntu Help, and
session options (like locking your computer, user/guest session, logging
out of a session, restarting the computer, or shuing down completely).
Figure 2.2: The indicators of the menu bar.Every application has a menuing system where different actions can be
executed in an application (like File, Edit, View, etc.); the menuing system
for an application is appropriately called the application menu. In Unity,
the application menu isn’t on the title bar of the application as is commonly
the case in other  environments. Instead, it is located to the le area Note that some older applications may still
display their menu within the application
window.
of the menu bar. To show an application’s menu, just move your mouse
to the desktop’s menu bar (at the top of the screen). While your mouse is
positioned here, the active application’s menu options will appear in the
desktop’s menu bar, allowing you to use the application’s menuing options.
When clicking on the desktop, the desktop’s menu bar reappears. is
capability in Unity to display the application’s menu only when needed is
especially beneficial for netbook and laptop users with limited viewable
screen space. Apple uses a similar approach in   where all application
menus appear on a bar at the top of the screen. It differs, however, in that
the menus in Ubuntu appear only when the mouse is over the desktop’s
menu bar.

The Launcher
e vertical bar of icons on the le side of the desktop is called the Launcher.
e Launcher provides easy access to applications, mounted devices, and
the Trash. All running applications on your system will place an icon in the
Launcher while the application is running.
Figure 2.3: The Ubuntu Launcher on the left
with a sample of applications on it.
To change the Launcher icon size, go to Session Indicator ‣ System
Settings ‣ Appearance, tab Look.
e first icon at the top of the Launcher is the Dash, a component of
Unity. We will explore the Dash in a later section of this chapter. By default,
other applications appear in the Launcher, including the Files file manager,
LibreOffice, Firefox, any mounted devices, and the Trash, which contains
deleted folders and files, at the boom of the Launcher.
Holding the Super key, also known as the Windows key (Win key),
located between the le Ctrl key and Alt key, will cause Ubuntu to super-
impose a number onto the first ten applications in the Launcher and also
display a screen full of useful shortcuts. You can launch an application with
a number n on it by typing Super+n.
If you open more applications than can be shown in the Launcher, the
Launcher will “fold” the application icons at the boom of the Launcher.
Simply move your mouse to the boom of the Launcher, and you’ll see
the Launcher icons “slide” and the folded application icons unfold for easy
access.
Running applications
To run an application from the Launcher (or cause an already-running
application to appear), just click on the application’s icon.
Applications that are currently running will have one or more triangles
on the le side of the icon indicating the number of application windows
open for this application. Running applications also have a back-lit icon on
the Launcher. Some also refer to an application in the
foreground as being in focus.
Figure 2.4: The triangles on each side of the
Firefox icon indicate Firefox is in the foreground
and only one window is associated with Firefox
at this time.
e application in the foreground (i.e. the application that is on top of all
other open application windows is indicated by a single white triangle on
the right side of its icon.
You can also run an application through the Dash which will be explored
in the upcoming e Dash section.
Adding and removing applications from the Launcher
ere are two ways to add an application to the Launcher:
‣ Open the Dash, find the application you wish to add to the Launcher, and
drag its icon to the Launcher.
‣ Run the application you want to add to the Launcher, right-click on the
application’s icon on the Launcher, and select Lo to Launer.
To remove an application from the Launcher, right-click on the applica-
tion’s icon, then select Unlo from Launer.
The Dash
e Dash helps you quickly finding applications and files on your computer. For more information about the Dash and its
lenses, see: https://wiki.ubuntu.com/Unity.If you’ve used Windows in the past, you’ll find the Dash to be similar to
the Windows Start menu or the Start Screen in Windows . Mac users will

find the Dash similar to Launchpad in the dock. If you’ve used a previous
version of Ubuntu or another  Linux distribution, the Dash serves
as a replacement for the various   menus. e Dash allows you
to search for information, both locally (installed applications, recent files,
bookmarks, etc.) as well as remotely (Twier, Google Docs, etc.).
Figure 2.5: The Dash
To explore the Dash, click on the top-most icon on the Launcher; the
icon contains the Ubuntu logo on it. Aer clicking the Dash icon, the desk-
top will be overlaid by a translucent window with a search bar on top as
well as a grouping of recently accessed applications, files, and downloads.
Ubuntu also includes results from popular web services. e search bar
provides dynamic results as you enter your search terms.
Lenses
Searching is accomplished by utilizing one or more lenses, also known as
scopes; each lens is responsible for providing a category of search results
for the Dash. e seven lenses installed by default at the boom are links
to your Home lens ( ), Applications lens ( ), Files and Folders lens ( ),
Music lens ( ), Photo lens ( ), Videos lens ( ), and Social network
messages lens ( ).
Lenses act as specialized search categories in the Dash. From the user’s
perspective, lenses are simply icons. To the Ubuntu purist, the pictures that
appear horizontally at the boom of the Dash are lenses; to the rest, these
are icons.
Many sites exist on the Internet dedicated to creating and releasing
lenses for the Ubuntu Unity desktop. Some sites even teach you how to
make your own lenses in order to maximize the operational efficiencies of
the Ubuntu Unity interface.
Search for files and applications with the Dash
e Dash is an extremely powerful tool allowing you to search your com-
puter for applications and files.

Find files/folders
e Dash can help you find names of files or folders. Simply type a portion
of the file or folder name. As you type, results will appear in the Dash. e
Files and Folders lens will also assist in finding files or folders—showing
you the most recently accessed files as well as the most recent downloads.
You can use the filter results buon in the top-right corner of the Dash to
filter results by aributes such as file or folder modification times, file type

Dash, and the names of applications matching your search criteria will
appear. Even if you don’t remember the name of the application at all, type
a keyword that is relevant to that application, and the Dash will find it. For
example, type music, and the Dash will show you the default music player
and any music player you’ve used.
Figure 2.6: You can see the default results when
you press the Applications lens.
External search results
In addition to searching your local computer for applications and files, the
Dash will also search various online resources (e.g., Amazon.com). Results
pertinent to your search criteria are returned to you in the Dash. If you are
concerned about local search terms being sent over the Internet, you can
disable this feature in the Privacy section of the System Seings.

e online search results within the Dash are turned on by default during in-
stallation. If you do not want external search results, go to System Settings ‣
Privacy ‣ Sear Results and set the “Include online search results” switch to
the Off position. As an added layer of privacy, you can also prevent any search
activity from being recorded.
Workspaces
Workspaces are also known as virtual desktops. ese separate views of
your desktop allow you to group applications together, and by doing so,
help to reduce cluer and improve desktop navigation. For example, you
can open all of your media applications in one workspace, your office suite
in another, and your web browser in a third workspace. Ubuntu has four
workspaces by default.
e workspaces feature is not activated by default in Ubuntu. To activate
workspaces, click on Session Indicator ‣ System Settings… ‣ Appearance
then click on the Behavior tab and click on the Enable workspaces box.
When this box is checked, you’ll notice another icon is added to the boom
of the Launcher that looks like a window pane. is is the workspaces
switcher.
Switching between workspaces
If you’ve activated the workspace switcher as described above, you can
switch between workspaces by clicking on the workspace switcher icon
located on the Launcher. is utility allows you to toggle through the
workspaces (whether they contain open applications or not) and choose the
one you want to use.
Figure 2.7: The workspace switcher on the
Launcher.
Managing windows
When opening a program in Ubuntu (such as a web browser or a text editor
—see Chapter : Working with Ubuntu for more information on using
applications)—a window will appear on your desktop. e windows seen in
Ubuntu are very similar to those in Microso Windows or Mac  . Simply
stated, a window is the box that appears on your screen when you start a
program. In Ubuntu, the top part of a window (the title bar) will have the
name of the application to the le (most oen, the title will be the same
as the application’s name). A window will also have three buons in the
top-le corner. From le to right, these buons represent close window,
minimize window, and maximize window. Other window management
options are available by right-clicking anywhere on the title bar.
Closing, maximizing, restoring, and minimizing windows
To close a window, click on the close buon ( ) in the upper-le corner of
the window—the first buon on the le-hand side. e buon immediately
to the right of the close buon is the minimize buon ( ) which removes
the window from the visible screen and places it in the Launcher. Figure 2.8: This is the top bar of a window,
named title bar. The close, minimize, and
maximize buttons are in the top-left corner of
the window.
is buon doesn’t close the application; it just hides the application
from view. When an application is minimized to the Launcher, the le-side
of the icon in the Launcher will display a triangle showing you the appli-
cation is still running. Clicking the icon of the minimized application will

   
restore the window to its original position. Finally, the right-most buon
is the maximize buon ( ) which causes the application to completely fill
the unused displayable space on the desktop. Clicking the maximize buon
again will return the window to its original size. If a window is maximized,
its top-le buons and menu are automatically hidden from view. To make
them appear, just move your mouse to the menu bar.
Moving and resizing windows
To move a window around the workspace, place the mouse pointer over the
window’s title bar, then click and drag the window while continuing to hold
down the le mouse buon. You can also move a window by holding the
Alt key and then clicking and holding the le mouse buon while pointing
at the title bar of the window and dragging the window to a new location.
To resize a window, place the pointer on an edge or corner of the window
so that the pointer turns into a larger, two-sided arrow (known as the resize
icon). You can then click and drag to resize the window.
Switching between open windows
In Ubuntu, there are many ways to switch between open windows.
. If the window is visible on your screen, click any portion of it to raise it
above all other windows.
. Use Alt+Tab to select the window you wish to work with. Hold down
the Alt key, and keep pressing Tab until the window you’re looking for
appears highlighted in the popup window. en, release the Alt key, and
the application highlighted in the popup will move to the foreground of
your desktop.
. Click on the corresponding icon on the Launcher by moving your mouse
to the le side of the screen and right-clicking on the application’s icon.
If the application has multiple windows open, double-click on the icon in
order to select the desired window.
. Press Ctrl+Super+D to hide all windows and display the desktop; the
same works to restore all windows.
Moving a window to different workspace
To move a window to a different workspace, verify that the window isn’t
maximized. If it is maximized, click on the right-most buon on the le
side of the title bar to restore it to its original size. en right-click on the
window’s title bar and select:
‣ Move to Workspace Le, to move the window to the le workspace
‣ Move to Workspace Right, to move the window to the right workspace
‣ Move to Workspace Down, to move the window to the boom workspace
‣ Move to Another Workspace, and then choose the workspace to where
you wish to move the window.
Note that the options available when moving windows to different
workspaces depends on which workspace contains the window you are
moving. If the window exists in the lower-right workspace, you will not see
a Move to Workspace Down because there is no workspace available below
the lower-right quadrant of a four quadrant workspace.

Window always on the top or on visible workspace
At times, you may want to force a window to always be in the foreground
so that it can be seen or monitored while you work with other applications.
For example, you may want to browse the web and, at the same time, view
and answer incoming instant message. To keep a window always in the

windows across all workspaces.
Browsing files on your computer
ere are two ways to locate files on your computer—search for them or ac-
cess them directly from their folder. You can search for a file using the Dash
or the Files file manager. You can also use the Dash or Files file manager to
access commonly used folders (such as Documents, Music, Downloads) as
well as the most recently accessed files.
Your Home Folder
e Home folder is used to store personal files. Your Home folder matches
your login name and is created when your user account is created. When
opening your personal folder, you will see a collection of several folders,
including Desktop (which contains any files that are visible on the desktop),
Documents, Downloads, Music, Pictures, Public, Templates, and Videos.
ese folders are created automatically during the installation process. You
can add more files and folders as needed.

Hidden Files and Folders
If you wish to hide certain folders or files, place a dot (.) in front of the
name (e.g., “.Personal Finances”). In some cases, it is impossible to hide files
and folders without prefixing them with a dot.
You can easily view hidden files by clicking View options ‣ Show Hidden
Files or by pressing Ctrl+H. Hiding files with a dot (.) is not a security
measure—it is simply a way to help you organize your files.
Copying and moving files and folders
You can cut, copy, and paste files or folders in the Files file manager by
right-clicking on the item and selecting the corresponding buon from the
popup menu. You can also use the keyboard shortcuts Ctrl+X, Ctrl+C, and
Ctrl+V to cut, copy, and paste files and folders, respectively.
Multiple files can be selected by le-clicking in an empty space (i.e.,
not on a file or folder), holding the mouse buon down, and dragging the
cursor across the desired files or folders. is “click-drag” action is useful
when you are selecting items that are grouped closely together. To select
multiple files or folders that are not positioned next to each other, hold
down the Ctrl key while clicking on each item individually. Once the
desired files and/or folders are selected, right-click on any of the selected
items to perform an action just like you would for a single item.
When one or more items have been “copied,” navigate to the desired
location, then right-click in an empty area of the window and select Paste
to copy them to the new location. While the copy command can be used
to make a duplicate of a file or folder in a new location, the cut command
can be used to move files and folders. at is, a copy will be placed in a new
location, and the original will be removed from its current location.
Note that when you “cut” or “copy” a file or folder, nothing will hap-
pen until you “paste” it somewhere. Paste will only affect the most recent
item(s) cut or copied.
To move a file or folder, select the item to move, then click Edit ‣ Cut.
Navigate to the desired location, then click Edit ‣ Paste. If you click on
a file or folder, drag it, then hold down the Alt key and drop it to your
destination folder, a menu will appear asking whether you want to copy,
move, or link the item.
As with the copy command above, you can also perform this action using
the right-click menu, and it will work for multiple files or folders at once.
An alternative way to move a file or folder is to click on the item, and then
drag it to the new location.
Using multiple tabs and multiple Files windows
Opening multiple Files file manager windows can be useful for dragging
files and folders between locations. You can also have multiple tabs to
browse multiple locations at once.
To open a second window when browsing a folder in Files, select File ‣
New Window or press Ctrl+N. is will open a new window, allowing you
to drag files and/or folders between two locations. To open a new tab, click
Location options (cog) ‣ New Tab or press Ctrl+T. A new row will appear
above the space used for browsing your files containing two tabs—both will
display the folder you were originally browsing. You can click these tabs
to switch between them to click and drag files or folders between tabs the
same as you would between windows.

   
When dragging items between Files windows or tabs a small symbol
will appear over the mouse cursor to let you know which action will be
performed when you release the mouse buon. A plus sign (+) indicates
you are about to copy the item, whereas a small arrow means the item will
be moved. e default action will depend on the folders you are using.
Searching for files and folders on your computer
You can search for files and folders using the Dash or the Files file manager. Search for files and folders quickly by pressing
Ctrl+F in Files and then typing what you want
to find.
Search using the Dash
In the Dash, simply type your search terms in the search bar at the top of
the Dash.
Alternatively, you may use the Applications or Files & Folders lenses;
here you can use a filter to narrow down your search. Open the drop-down
menu on the right side of the search bar. If you’ve selected Applications,
you will be able to filter by application type. If you’ve chosen Files & Fold-
ers, you can filter by a host of options, including Last modified, Type (e.g.,
Documents), or Size. It is sufficient to type the first few leers of the file or
folder for which you are searching.
Search using Files file manager
In Files file manager, click on the magnifying glass buon or press Ctrl+F.
is opens the search field where you can type the name of the file or folder
you want to find.
Customizing your desktop

Accessibility
Ubuntu has built-in tools that make using the computer easier for people
with certain physical limitations. You can find these tools by opening the
Dash and searching for “Universal Access” or by selecting Session Indica-
tor ‣ System Settings ‣ Universal Access. Use the Seeing tab to manage the
text size, the contrast of the interfaces, enable a zoom tool, or even a screen
reader. Selecting high-contrast themes and larger on-screen fonts can assist
those with vision difficulties. You can activate “Visual Alerts” through the
Hearing tab if you have hearing impairment. You can also adjust keyboard
and mouse seings to suit your needs through the Typing and Pointing and
Cliing tabs, respectively.

Orca screen reader
Orca is a useful tool for people with visual impairments. Orca comes pre-
installed in Ubuntu. To run Orca, click on the Dash, type Orca, and click
on the displayed result. Orca is the “Screen Reader” part of Universal Ac-
cess and can be launched once the “Screen Reader” is activated. Orca’s
voice synthesizer will activate and assist you through the various options
such as voice type, voice language, Braille, and screen magnification. Once
you have finished selecting your seings, you will need to log out of the
computer (Orca will offer to do this for you). When you log back in, the
Orca seings you selected will automatically run every time you use your
computer.
Session options
When you have finished working on your computer, you can choose to log
out, suspend, restart, or shut down through the Session Indicator on the far
right side of the top panel.
Logging out
Logging out will leave the computer running but return the desktop to
the login screen. is is useful for switching between users, such as when
a different person wishes to log in to their account or if you are ever in-
structed to “log out and back in again.” You can also log out by pressing
Ctrl+Alt+Del. Before logging out, always verify that you have saved your
work in any open application.
Suspend
To save energy, you can put your computer into suspend mode which will
save the current opened applications to internal memory, power off all
internal devices and hardware, and allow you to start back up more quickly.
While in a suspended state, the computer will use just a trickle of energy;
this is required because the session is saved to internal memory, and if no
power goes to internal memory, the data will be lost. To put your computer
in suspend mode, select suspend from the “Session Indicator”.
Rebooting
To reboot your computer, select Shut Down from the “Session Indicator”
and click the Restart icon.
Shut down
To totally power down your computer, select Power Off from the “Session
Indicator” and click Power Off.
Other options
From the “Session Indicator”, select Lo/Swit Account to either lock the
screen of the current user or switch user accounts. You can lock your screen
quickly by using the keyboard shortcut Ctrl+Alt+L. Locking your screen is
recommended if you are away from your computer for any amount of time.

Online Help
If you can’t find an answer to your question in this manual or in the
Ubuntu Desktop Guide, you can contact the Ubuntu community through
the Ubuntu Forums (http://ubuntuforums.org).
Many Ubuntu users open an account on the forums to receive help and
in turn provide support to others as they gain more knowledge. Another
useful resource is the Ubuntu Wiki (https://wiki.ubuntu.com/community), a
website maintained by the Ubuntu community. On https://help.ubuntu.com

Getting online
is section of the manual will help you to check your connection to the
Internet and help you configure it where needed. Ubuntu can connect to the
Internet using a wired, wireless, or dialup connection. Ubuntu also supports
more advanced connection methods, which will be briefly discussed at the
end of this section.
A wired connection is when your computer connects to the Internet
using an Ethernet cable. is is usually connected to a wall socket or a
networking device—like a switch or a router.
A wireless connection is when your computer connects to the Internet
using a wireless radio network—usually known as Wi-Fi. Most routers now

     .
come with wireless capability, as do most laptops and netbooks. Because of
this, Wi-Fi is the most common connection type for these types of devices.
Wireless connectivity makes laptops and netbooks more portable when
moving to different rooms of a house and while travelling.
A dialup connection is when your computer uses a modem to connect to
the Internet through a telephone line.
NetworkManager
(a) (b) (c)
Figure 3.1: The network connection states: (a)
disconnected, (b) wired, and (c) wireless.
In order to connect to the Internet using Ubuntu, you need to use the Net-
workManager utility. NetworkManager allows you to turn network con-
nections on or off, manage wired and wireless networks, and make other
network connections, such as dialup, mobile broadband, and s.
Figure 3.2: Here you can see the currently active
connection is “Wired connection 1.”
You can access NetworkManager by using its icon found in the top panel.
is icon may look different depending on your current connection state.
Clicking this icon will reveal a list of available network connections. e
current connection (if any) will have the word “disconnect” underneath it.
You can click on “disconnect” to manually disconnect from that network.
is menu also allows you to view technical details about your current
connection or edit all connection seings. In the image to the right, you
will see a check mark next to “Enable Networking.” Deselect “Enable Net-
working” to disable all network connections. Select “Enable Networking” to
enable networking again. is can be very useful when you are required to
turn off all wireless communications, like in an airplane.
Establishing a wired connection
If you are already online at this point as indicated by the NetworkManager
icon in the top panel showing a connection, then you may have successfully
connected during the Ubuntu setup process. You can also simply open a
browser and see if you have access to the Internet. If so, you do not need to
do anything for the rest of this section. If not, then continue reading.
If you have an Ethernet cable running from a wall socket or networking
device, such as a switch or router, then you will want to setup a wired
connection in Ubuntu.
In order to connect to the Internet with a wired connection, you need to
know whether your network supports  (Dynamic Host Configuration
Protocol).  is a way for your computer to automatically be configured
to access your network and/or Internet connection.  is usually auto-
matically configured on your router. is is usually the quickest and easiest
way of establishing a connection to the Internet. If you are unsure whether
your router is setup to use , you may wish to contact your ’s (In-
ternet Service Provider) customer service line to check. If your router isn’t
configured to use  then they will also be able to tell you what configu-
ration seings you need in order to get online.

Automatic connections with DHCP
Figure 3.3: This window displays your IP address
and other connection information.
If your network supports , then you may already be set up for on-
line access. To check this, click on the NetworkManager icon. ere should
be a “Ethernet Network” heading in the menu. If “Wired connection ” ap-
pears directly underneath, then your machine is currently connected and
probably setup for . If “Disconnected” appears in gray underneath the
wired network section, look below to see if an option labeled “Wired con-

window showing details of your connection. If your  address is displayed
as ... or starts with ., then your computer was not successfully
assigned connection information through . If it shows another address
(e.g., ...), then it is likely that your  connection to the
router was successful. To test your Internet connection, you may want to
open the Firefox web browser to try loading a web page. More information
on using Firefox can be found later in this chapter.
Manual conﬁguration with static address
If your network does not support , then you need to know a few items
of information before you can get online. If you do not know any of this
information, then you call your .
‣ An  address—is is a unique address used for identifying your com-
puter on the network. An  address is always given in four numbered
groups, separated by dots, for example, .... When connect-
ing using , this address will periodically change (hence, the name
“dynamic”). However, if you have conﬁgured a static  address, your 
address will never change.
‣ A network mask—is tells your computer the size of the network to
which it is being connected. It is formaed the same way as the  ad-
dress, but usually looks something like ....
‣ A gateway—is is the  address of the device that your machine looks
to for access to the Internet. Usually, this will be the router’s  address.
‣  server—is is the  address of the  (Domain Name Service)
server.  is what your computer uses to resolve  addresses to domain

     .
names. For example http://www.ubuntu.com resolves to ....
is is the  address of the Ubuntu website on the Internet.  is
used so you don’t have to remember  addresses. Domain names (like
ubuntu.com) are much easier to remember. You will need at least one
 server address but you can enter up to three addresses in case one
server is unavailable. If you do not know your ’s  server addresses,
Google has  servers that anyone in the world can use for free. e
addresses of these servers are: Primary—... Secondary—....
To manually configure a wired connection, click on the NetworkManager
icon and select Edit Connections. Make sure you are looking at the Wired
tab inside the “Network Connections” window. e list may already have
an entry, such as “Wired connection ” or a similar name. If a connection is
listed, select it and click the Edit buon. If no connection is listed, click the
Add buon.
If you are adding a connection, you need to provide a name for the
connection. is will distinguish the connection being added from any
other connections added in future. In the “Connection Name” field, choose a
name such as “Wired Home.”

A  address is a hardware address for your computer’s network card. Entering
this information is sometimes important when using a cable modem connection.
If you know the  address of your network card, this can be entered in the
appropriate text field in the Wired tab of the editing window. To find the 
addresses for all installed networking devices, open a terminal window, and at
the command line prompt, type ifconfig. is will display a lot of information
about each of the network devices installed on the computer. e wired devices
will be labeled as LAN, LAN, etc. e wireless devices will appear as WLAN,
WLAN, etc.
When you have returned to the Network Connections screen, your
newly added connection should now be listed. Click Close to return to the
desktop. If your connection was configured correctly, the NetworkManager
icon should have changed to show an active wired connection. To test if
your connection is properly set up, simply open a web browser. If you can
access the Internet, then you are connected!
Wireless
If your computer is equipped with a wireless (Wi-Fi) card and you have a
wireless network nearby, you should be able to set up a wireless connection
in Ubuntu.
Connecting to a wireless network for the first time
If your computer has a wireless network card, you can connect to a wireless
network. Most laptops and netbooks have a built-in wireless networking
card.
Ubuntu is usually able to detect any wireless network in range of your
computer. To see a list of wireless networks, click on the NetworkMan-
ager icon. Under the “Wireless Networks” heading you should see a list of
available wireless networks. Each network will be shown by its name and a
signal meter to the le showing its relative signal strength. e signal meter
looks like a set of bars similar to what is seen when viewing signal strength
of a cell phone. Simply put, the more bars, the stronger the signal. To im-
prove speed and reliability of your wireless connection, try moving closer to
your router or wireless access point.
A wireless network can be open to anyone, or it can be protected with
a password. A small padlock will be displayed by the signal bar if any
wireless network within range are password-protected. You will need to
know the correct password in order to connect to these secured wireless
networks.
To connect to a wireless network, select the desired network by clicking
on its name within the list. is will be the name that was used during
the installation of the wireless router or access point. Most s (Internet
service providers) provide pre-configured routers with a sticker on them
detailing the current wireless network name and password. Most publicly
accessible wireless networks will be easily identifiable by the name used for
the wireless network—for example “Starbucks-Wireless.”
If the network is unprotected (i.e., the signal meter does not show a pad-
lock), a connection should be established within a few seconds—and with-
out a password required. e NetworkManager icon in the top panel will
animate as Ubuntu aempts to connect to the network. If the connection
is successful, the icon will change to display a signal meter. An on-screen

     .
notification message will also appear informing you that the connection
was successful.
If the network is password-protected, Ubuntu will display a window
called “Wireless Network Authentication Required” as it tries to make a
connection. is means that a valid password is required to make a connec-
tion. is is what the screen should look like:
Figure 3.5: Enter your wireless network
password.
If you know the password, enter it in the Password field and then click
on the Connect buon. As you type the password, it will be obscured from
view to prevent others from reading the password as you type it. To verify
the characters you are entering for the password, you can view the pass-
word by selecting the Show Password check box. en, you can make the
password obscure again by deselecting the Show password check box.
Once the password is entered, click on the Connect buon. e Network-
Manager icon in the top panel will animate as Ubuntu aempts to connect
to the network. If the connection is successful, the icon will change to dis-
play a signal meter. An on-screen notification message will also appear
informing you that the connection was successful.
If you entered the password incorrectly, or if it doesn’t match the cor-
rect password (for example if it has recently been changed and you have
forgoen), NetworkManager will make another aempt to connect to the
network, and the “Wireless Network Authentication Required” window will
re-appear so that you can re-type the password. You can hit the Cancel but-
ton to abort the connection. If you do not know the correct password, you
may need to call your ’s customer support line or contact your network
administrator.
Once you have successfully established a wireless connection, Ubuntu
will store these seings (including the password) to make it easier to con-
nect to this same wireless network in the future. You may also be prompted
to select a keyring password here. e keyring stores passwords in one
place so you can access them all in the future by remembering just the
keyring password.
Connecting to a saved wireless network
Ubuntu will automatically try to connect to a wireless network in range
if it has the seings saved. is works on both open and secure wireless
networks.
If you have numerous wireless networks in range that are saved on
your computer, Ubuntu may choose to connect to one network while you
may want to connect to another network. To remedy this action, click on
the NetworkManager icon. A list of wireless networks will appear along
with their signal meters. Simply click on the network to which you wish to
connect, and Ubuntu will disconnect from the current network and aempt
to connect to the one you have selected.
If the network is secure and Ubuntu has the details for this network

   
saved, Ubuntu will automatically connect. If the details for this network
connection are not saved, are incorrect, or have changed, then you will be
prompted to enter the network password again. If the network is open (no
password required), all of this will happen automatically and the connection
will be established.
Connecting to a hidden wireless network
In some environments, you may need to connect to a hidden wireless net-
work. ese hidden networks do not broadcast their names, and, therefore,
their names will not appear in the list of available wireless networks even
if they are in range. In order to connect to a hidden wireless network, you
will need to get its name and security details from your network adminis-
trator or .
To connect to a hidden wireless network:
. Click on NetworkManager in the top panel.
. Select Connect to a hidden wireless network. Ubuntu will then open
the “Connect to Hidden Wireless Network” window.
. In the Network name field, enter the name of the network. is is also
known as the  (Service Set Identifier). You must enter the name ex-
actly how it was given to you. For example, if the name is “Ubuntu-
Wireless,” entering “ubuntu-wireless” will not work as the “U” and “W”
are both uppercase in the correct name.
. In the Wireless security field, select one of the options. If the network
is an open network, leave the field set to “None.” If you do not know the
correct seing for the field, you will not be able to connect to the hidden
network.
. Click the Connect buon. If the network is secure, you will be prompted
for the password. Provided you have entered all of the details correctly,
the network should then connect, and you will receive an on-screen
notification informing you that the connection was a success.
As is the case with visible wireless networks, hidden wireless network
seings will be saved once a connection is made, and the wireless network
will then appear in the list of saved connections.
Disabling and enabling your wireless card
By default, wireless access is enabled if you have a wireless card installed in
your computer. In certain environments (like on airplanes), you may need
to temporarily disable your wireless card.
To disable your wireless card, click on the NetworkManager icon and
deselect the Enable Wireless option. Your wireless radio will now be turned
off, and your computer will no longer search for wireless networks.
To reactivate your wireless card, simply select the Enable Wireless op-
tion. Ubuntu will then begin to search for wireless networks automatically.
If you are in range of a saved network, you will automatically be connected.
Many modern laptops also have a physical switch/buon built into the
chassis that provides a way to quickly enable/disable the wireless card.
Changing an existing wireless network
At times you may want to change the seings of a saved wireless network
—for example, when the wireless password gets changed.
To edit a saved wireless network connection:

     .
. Click on the NetworkManager icon and select Edit Connections…
. A “Network Connections” window will open. Click on the Wireless tab.
. By default, saved networks are in chronological order with the most
recently connected at the top. Find the network you want to edit, select
it, and click on the Edit buon.
. Ubuntu will now open a window called “Editing 〈connection name〉”,
where 〈connection name〉 is the name of the connection you are editing.
is window will display a number of tabs.
. Above the tabs, there is a field called Connection name where you can
change the name of the connection to give it a more recognizable name.
. If the Connect automatically option is not selected, Ubuntu will detect
the wireless network but will not aempt a connection until it is se-
lected from the NetworkManager menu. Select or deselect this option as
needed.
. On the Wireless tab, you may need to edit the  field. A  is the
wireless connection’s network name. If this field isn’t set correctly,
Ubuntu will not be able to connect to the wireless network in question.
. Below the  is a Mode field. e “Infrastructure” mode means that
you would be connecting to a wireless router or Access Point. e “ad-
hoc” mode is for a computer-to-computer connection (where one com-
puter shares another’s connection) and is oen only used in advanced
cases.
. On the Wireless Security tab, you can change the Security field. A
selection of “None” means that you are using an open network that
doesn’t require a password. Other selections in this tab may require
additional information:

History
Whenever you are browsing the web, Firefox saves your browsing history.
is allows you to come back to a web page that you have recently visited
without needing to remember or bookmark the page’s .
To see your most recent history, open the History menu from the top
bar. e menu displays several of the most recent web pages that you have
viewed. Choose one of the pages to return to it.
To view the complete history, either:
‣ Select View ‣ History or press Ctrl+H to view the history in a sidebar;
this replaces the bookmarks sidebar if it is open. (Repeat, or press the
close button at its top, to hide the sidebar.)
‣ Select History ‣ Show All History or press Shift+Ctrl+H to view the
history in a pop-up window.
Your browsing history is categorized as “Today,” “Yesterday,” “Last 
days,” “is month,” the previous ﬁve months by name, and ﬁnally “Older
than  months.” If the history for a category does not exist, that category
will not be listed. Select one of the date categories in the sidebar to expand

page you want, select it to re-display it.
You can also search for a page by its title or . Enter a few leers
from one or more words or, optionally, the  in the Sear field at the
top of the history sidebar. e sidebar displays a list of web pages matching
your search words. Select the page you want. (You can even do this in the
Location Bar, saving you from having to open the History sidebar or pop-up
window.)
Clearing private data
Firefox stores all its data only on your computer. Nevertheless, if you share
your computer, you may at times want to delete all private data.
Select Tools ‣ Clear Recent History or press Shift+Ctrl+Delete. Choose
your Time range to clear, and under Details which items to clear, and press
Clear Now.
Preventing Firefox from recording private data
You can start a “private browsing” session during which Firefox will not
record anything permanently. is lasts until you disable private browsing
or restart Firefox.
Choose Tools ‣ Start Private Browsing or press Shift+Ctrl+P. Press the
Start Private Browsing buon to confirm. As long as you remain in this
mode, Firefox will not record browsing, download, form or search history,
or cookies, nor will it cache files. However, if you bookmark anything or
download files, these will be retained.
Repeat Tools ‣ Start Private Browsing or Shift+Ctrl+P, or restart Fire-
fox, to end private browsing.

Reading and composing email
Introduction to Thunderbird
underbird is an email client developed by Mozilla and is easy to setup and
use. It is free, fast, and comes packed full of useful features. Even if you are
new to Ubuntu and underbird, you will be up and running in no time,
checking your email and staying in touch with friends and family.
Setting up Thunderbird
In the top right corner of the Ubuntu desktop you will see an envelope
icon in the notification area. is is the messaging menu. From here, you
can launch underbird by clicking Set up Mail. Alternatively, you can
click the Ubuntu buon in the top le corner of the screen at the top of the
Launcher to bring up the Dash and type thunderbird into the search box.
Once underbird opens, you will be greeted by a pop-up box prompting
you to setup your email account.
Figure 3.12: Setting up Thunderbird
Before a valid email account is set up in underbird, the first screen to
appear will be an introductory message from Mozilla inviting you to set
up an email account through a local service provider in your area. For the
purposes of these instructions, we will assume you already have an email
address, so you can click on the buon in the lower right corner of the
screen that says Skip this and use my existing email.
On the next screen titled Mail Account Setup, enter your name in the
first text box, your email address in the second text box (for example, user-
name@domain.com), and your email password in the third text box.
Once completed, click the Continue buon. underbird will auto- If Thunderbird fails to create the account,
you may need to configure it manually, using
the parameters that were sent to you by your
email address provider and your ISP. If you
are still unable to set up your account, you

matically set up your email account for you. When underbird finishes
detecting your email seings, click Create Account and underbird will do
the rest. You can also set underbird as your default news and  reader
by checking the boxes in the pop-up box that appear aer you click Create
Account. If you don’t want to see this message box every time you start
underbird, simply deselect Always perform this e when starting
underbird. You are now ready to start using underbird.

Around the Thunderbird workspace
Now that you have your email account set up, let’s get to know the un-
derbird workspace. underbird is designed to be very user-friendly and
easy to navigate. When you open the application, you will see the main
workspace with your email folders (all folders window) on the le. On the
right of the screen, you will see two windows. e top-right window dis-
plays a list of your received email, and the boom-right window displays
the current email you are viewing. e size of these windows can be easily
resized to suit your viewing environment. To resize the windows, simply
le-click and hold the dividing bar that separates two windows and drag it
to the desired position. e All Folders window is where you can see your
mail folders. is window can also include:
Inbox Where your email is stored and accessed
Email address folder You will see one of these folders for each of the ac-
counts you have setup
Dras Where your dra emails are stored
Sent mail Where the emails you have sent are stored
Spam is is where suspected spam email is stored so you can check them
to make sure you haven’t lost any important emails
Trash is is where messages you’ve deleted are stored so you can double
check to make sure you haven’t accidentally deleted an important email
(also one of the local folders)
Important is is where emails you have marked as important are stored
Starred is is where emails you have marked with a star are stored
Personal is is where emails you have marked as personal are stored
Receipts You can move important receipts to this folder.
Travel You can use this folder to store travel emails such as flight times and
bookings
Work You can store work emails in this folder to keep them separate from
your personal email
Outbox Where the emails you are in the process of sending are stored (also
one of the local folders)
Across the top of the underbird workspace, you will see at least four
control buons, Get Mail, Write, Address Book, and Tag. ese are used to
get your mail, write your mail, access your address book, and tag your email
messages.
At the top-right of the All Folders window, you will see a set of quick
filter buons, Unread, Starred, Contact, Tags, and Attament. You can use
these buons to filter your email messages so that you only see your unread
mail, your favorite mail (starred), mail from people in your address book,
mail you have tagged, and mail that includes aachments.
If you are accustomed to a more traditional desktop and you have un-
derbird maximized to full screen, you might be wondering where the menus
are located. ey are still there, and if you want to access them, move your
mouse to the top of the screen and you will see the familiar menus: File,
Edit, View, Go, Message, Tools, and Help.
At the top of the window that displays your email, you can see six action
buons, Reply, Reply All, Forward, Arive, Junk, and Delete. You will
find these very useful for quickly replying to email, forwarding your email
to another person, archiving (backing up) your email, marking an email as
junk mail, and quickly deleting an email. To the le of these quick action
buons, you will see information about the email you are viewing that

     .
includes the sender’s name, the subject of the email, the reply address, and
the recipient of the email.
Using your address book
At the top of the main workspace, you will see the Address Book buon.
Click this buon to access your address book. e address book opens in a
new window. From here, you can easily organize your contacts. At the top
of the address book window, you will see five buons, New Contact, New
List, Properties, Write, and Delete. ey function in the following ways:
New Contact is buon allows you to add a new contact and add as much
detail as you wish to save, including name, nickname, address, email,
additional email, screen name, work number, home number, fax, pager
and mobile/cell number.
New List is buon allows you to add lists for your contacts such as
family, friends, acquaintances, etc.
Properties is buon allows you to rename your address book name. e
default name is personal address book, but you can change the name as
you see fit.
Write is buon allows you to quickly send an email to a selected contact
without needing to go back to the main underbird workspace. Simply
select a contact from your contacts list and click the Write buon to
send them an email.
Delete is buon allows you to quickly delete a contact from your address
book. Just select the contact you want to delete and press Delete to
remove the contact from your address book.
Checking and reading messages
underbird will automatically check your email account for new mes-
sages every ten minutes, but if you need to manually check for new mes-
sages at any time, le-click the Get Mail buon in the top le corner of
the workspace. underbird will then check your email account for new
messages and download them.
As they are downloaded, you will see the new email appear in the mes-
sage window on the right side of the workspace. When you click on one of
your emails, it will appear in the window below your email list. If you want
to view your email in a full window, double-le-click your chosen email,
and underbird will display the email in a full window in its own tab.
At the top of the open email, you will see information about the email Remote content represent parts of an email
that may be hosted elsewhere. Remote content
might consist of video or audio, but most
often is graphics or HTML content. For security
purposes, Thunderbird will ask you if you wish
to view this remote content.
and the five quick action buons, Reply, Forward, Arive, Junk and
Delete as previously discussed. If an email has remote content, you will
see a message asking if you want to display the email or not.
You may want to filter your emails from time to time; this is easily done
with underbird. When you have an email selected and you want to tag
the email, simply click the Tag buon and a drop-down list will be dis-
played. In this drop-down list, you have the options to Remove All Tags or
Mark as…, Important, Work, Personal, To Do, Later. You can also create a
New Tag more suited to your own personal requirements.
Composing Messages
To compose a new email message, click the Write buon in the top le of
the workspace. is will bring up a new window where you can compose

   
your new email. In the To: field, enter the email address of the destination
—the contact to whom you are sending this email. If there is more than one
contact to whom you are writing, separate multiple recipients with commas.
If a contact that you are addressing is in your address book, you can
address them by name. Start typing the name of the contact; underbird
will display the list of mailing contacts below your text. Once you see the
contact you intend to address, click on their email address or use the down
arrow key and then press Enter to select the address.
If you would like to carbon-copy (Cc) some contacts, click the To: field
and select Cc:. Contacts who are listed on the To: and Cc: lines will receive
the email, and will see the rest of the contacts to whom an email was sent.
If you would like to send an email to some contacts without disclosing to
whom your email was sent, you can send a blind carbon-copy, or Bcc. To
enable Bcc, select Bcc: by clicking the To: field and selecting Bcc:. Any
contacts entered in the Bcc: field will receive the message, but none of the
recipients will see the names or emails of contacts on the Bcc: line.
Instead of typing the email addresses or names of the contacts you are
addressing in the message, you can select the contacts from your address
book. Start typing a few leers from your contact’s first or last name in the
To: field to filter the list to only show mailing contacts. Once you identify
the contact you would like to address, click on their name in the list. If
you’ve added the contact in error, delete their address and enter the correct
address.
You may enter a subject for your email in the Subject field. Messages
should have a subject to help the recipient identify the general contents of
the email while glancing at their message list. Enter the contents of your If you do not include a subject in your email,
Thunderbird will warn you about this omission.message in the big text field below the subject. ere is no practical limit on
the amount of text you can include in your message.
By default, underbird will auto-detect the correct format for your
email but you can change this by clicking Options then mouse over Format
and select your preferred option from the list. You have a choice of Auto-
Detect, Plain Text Only, Rich Text (HTML) Only, and Plain and Rich (HTML)
Text.
When you have finished composing your email, click on the Send buon
on the window’s toolbar. Your message will be placed in the Outbox, and
will be sent to your desired recipient.
Attaching files
At times, you may want to send files to your contacts. To send files, you
will need to aach them to your email message. To aach a file to an email You can attach quite a few different file types
to emails, but be careful about the size of the
attachments! If they are too big, some email
systems will reject the email you are sending,
and your recipient will never receive it!
you are composing, click on the Atta buon. When the new window
opens, select the file you want to send and click Open. e file you selected
will then be aached to the email when you click send.
Replying to Messages
In addition to composing new messages, you may want to reply to messages
that you receive. ere are three types of email replies:
Reply or Reply to Sender sends your reply only to the sender of the message
to whom you are replying.
Reply to All sends your reply to the sender of the message as well as any
address in To: or Cc: lines.

     .
Forward allows you to send the message, with any additional comments
you may add, to some other contacts.
To use any of these methods, click on the message to which you want
to reply and then click the Reply, Reply to All, or Forward buon on the
message toolbar. underbird will open the reply window. is window
should look much like the window for composing new messages, but the
To:, Cc:, Subject:, and main message content fields should be filled in from
the message to which you are replying. Edit the To:, Cc:, Bcc:, Subject: or
main body as you see fit. When your reply is finished, click on the Send
buon on the toolbar. Your message will be placed in the Outbox and will
be sent.
Using instant messaging
Figure 3.13: This is the icon that Empathy
displays in the launcher.
Instant messaging allows you to communicate with people in real time
online. Ubuntu includes the Empathy application that lets you use instant
messaging features to keep in touch with your contacts. Empathy lets
you connect to many instant messaging networks. You can connect to:
Facebook, Google Talk, Windows Live, Salut, Jabber, Yahoo!, and . To
start Empathy, open the Messaging Menu (the envelope icon on the menu
bar), then select Empathy. Note that you will only find it there aer you
have run Empathy for the first time (see below).
Figure 3.14: Access Empathy from the Messag-
ing Menu in the menu bar.
Running Empathy for the first time
To run Empathy for the first time you need to start it from the Dash (see
e Dash). You should see a screen similar to that in figure .. At this
time, Empathy does not know about any of your instant messaging ac-
counts.
Adding accounts
You must have existing chat accounts to that are compatible with Empathy. If
you do not have an existing account, you will need to create one before continu-
ing.
Be aware that when you Add or Remove
accounts using the Online Accounts manager
you will be adding or removing those accounts
to or from all the applications that they
integrate with, not just Empathy.
You can add accounts to be used with empathy by clicking the Account
Settings buon, as shown in figure ., or you can use the menu bar to

When you have authorized Ubuntu to access your account, you are
shown all the applications that integrate with the account, including Em-
pathy. All the applications have an ON/OFF buon to control their inte-
gration with the account. Make sure the ON/OFF buon is set to ON for
Empathy. ere is also an Options buon for you to edit details used by
Empathy. e details shown are specific to each application. Aer adding
your accounts, you can now use Empathy to chat with all of your friends,
right from your Ubuntu desktop!
Communicating with contacts

are chaing with is typing to you, a small keyboard icon will appear next to
their name in the chat window.
If you are communicating with more than one person, then all of the
conversations will be shown either in tabs in your Empathy window or in
separate windows, depending on the option you have chosen in the menu
item Empathy ‣ Preferences.
Audio and Video Calling
You can use Empathy to chat with your friends using audio and video,
too. To start an audio or video call, right click on the Contact name, then
select Audio Call or Video Call, as shown in ﬁgure .. is will notify the
person you are trying to call, and they will be asked if they would like to
answer the call.
Figure 3.19: Right-clicking a contact exposes
many ways to communicate.
If the person you are calling accepts your call request, you will be con-
nected, and you can begin talking. If the person you are calling cannot see
or hear you, your webcam or microphone may not be properly conﬁgured;
see the sections on Sound and Using a webcam, respectively. You can end
the call by clicking on the red telephone buon in the chat window.

Sending and receiving files
Sending a file
When you are in a conversation with a contact and you would like to send
them a file, right-click the contact in the contact list—as in figure .—
and select Send File. Empathy should open the “Select file” window. Find
the file you wish to send, and click on the Send buon. A “File Transfers”
window will open showing the file and its transfer progress. When the file
transfer is complete, you can close the “File Transfers” window.
Changing your status
You can use your status to show your contacts how busy you are or what
you are doing. Your contacts see your status next to your name when they
chat with you. You can use the standard statuses, which are:
‣ Available
‣ Busy
‣ Away
‣ Invisible
‣ Offline
Two of these statuses have additional functionality. e Invisible status
lets you see which of your contacts are online, but does not allow them to
see that you are online. e Offline status logs you out entirely; you will
not be able to see which of your contacts are online, nor can they see you or
chat with you.
You can change your status in one of two ways. e first method is
in the main Empathy window from the drop-down list at the top of the
window.
e same drop-down list lets you set a custom status by choosing “Cus-
tom Message…” next to the icon that matches your status. Enter what you
would like your status to say, and click on the green check mark.
e second method is to click the Messaging Icon on the menu bar, as
shown in figure .. From this menu, you will see all of the same options
that Empathy presents, but accessible without having to open Empathy.
Desktop Sharing
Desktop sharing is a very nice feature available with Ubuntu. It can be used
for a lot of purposes, like troubleshooting, online meetings, or just showing
off your cool desktop to your friend. It is very easy to get remote desktop
sharing working between two Ubuntu machines.
To share your screen, you will first have to set up Desktop Sharing. Open
the Desktop Sharing application from the Dash (see e Dash). Next, select
Allow other users to view your desktop; you may want to deselect Allow
other users to control your desktop.
Aer you have Desktop Sharing configured, open Empathy. To begin
sharing your desktop, right-click on the contact you wish to share your
desktop with, and select Share my desktop.
It should be noted that the other user will obviously be able to see the
information displayed on your screen. Please be sure to keep this in mind
if you have documents or files that are of a private nature open on your
desktop.

Ubuntu One
What is Ubuntu One?
Ubuntu One is a service for storing your files online in your Ubuntu One
Personal Cloud. Your Ubuntu One Personal Cloud is your personal on-
line storage space, and it can be accessed in any web browser or using an
Ubuntu One application (available for Ubuntu, Mac  , Windows, iPhone,
and Android). Because Ubuntu One stores your files online, it’s the perfect
way to backup your files to prevent data loss. You can also use Ubuntu One
to share files with other people—this makes Ubuntu One a great tool for
friends, families, and collaborative teams. Ubuntu One also provides ser-
vices for backing up your contacts and streaming music to mobile devices.
e Ubuntu One service is provided by Canonical.

   
How safe is Ubuntu One?
Before using Ubuntu One, you should keep the following points in mind:
‣ Uploading, downloading and synchronizing your information with
Ubuntu One is done over an encrypted connection which prevents any-
one from eavesdropping on your information as it is being transferred.
‣ Files are not stored by Canonical in encrypted form. It is important to
keep this in mind when deciding what to upload to Ubuntu One. You can
use other means to encrypt you data, such as an encrypted zip file.
‣ Information uploaded to Ubuntu One can potentially be accessed by
Canonical. As with similar online services and websites, you are implic-
itly trusting them to respect your privacy, so if you feel you cannot trust
them with certain information, don’t upload it to Ubuntu One.
‣ If you violate the Ubuntu One terms and conditions and store illegal
material, Canonical may be required to hand the information over to law
enforcement agencies without your consent.
‣ Your online information can be accessed by anybody who knows (or can
guess) your account name and password. For this reason, you should
choose a strong password and keep it secure.
Getting started with Ubuntu One
To use Ubuntu One, you will need to create a free Ubuntu One account
using an email address. is free account gives you access to   of online
storage and the contact syncing service; this amount of space is enough
to store about , music files or , photographs (depending media
quality). Increased data storage or the music streaming service requires a
paid subscription.
ere are two ways to create an Ubuntu One account. You can either
sign up using the Ubuntu One Control Panel (pre-installed in Ubuntu), or
you can sign up on the Ubuntu One website https://one.ubuntu.com by
clicking the Sign Up link.

Using Ubuntu One with the Ubuntu One Web UI
You can access your files from any computer using the Ubuntu One Web 
at https://one.ubuntu.com. A Web UI (User Interface) is a web site that you
can go to and do the same things that you do on your computer. Emails, for
instance, are commonly accessed through a Web UI. When you first reach
the web page, you will need to log in by clicking Log in or Sign up in the
upper right-hand corner of the page. On the following page, fill in your
email address and Ubuntu One password, then click the Continue buon.
Once logged in, you should be taken to your Dashboard. e Dashboard

Sharing Files
Ubuntu One lets you share files with other Ubuntu One users, leing you
collaborate on files with ease. When one user makes a change to a shared
file, the changes automatically sync to the other users’ personal clouds
and their local file system, so all users automatically have the most recent
version of the file.
Figure 3.34: Sharing folders with other users

4 Hardware
Using your devices
Ubuntu supports a wide range of hardware, and support for new hardware
improves with every release.
Hardware identification
ere are various ways to identify your hardware in Ubuntu. e easiest
would be to install an application from the Ubuntu Soware Center, called
Sysinfo.
Firstly, open the “Ubuntu Soware Center”, then use the search box in
the top right corner to search for sysinfo. Select the Application, click
Install. Enter your password when prompted, to install the application.
To run the application, search for Sysinfo at the Dash search bar. Click
on the program once you find it. e Sysinfo program will open a window
that displays information about the hardware in your system.
Displays
Hardware drivers
A driver is a piece of soware which tells your computer how to communi-
cate with a piece of hardware. Every component in a computer requires a
driver to function, whether it’s the printer,  player, hard disk, or graph-
ics card.
e majority of graphics cards are manufactured by three well-known Your graphics card is the component in your
computer which outputs to the display.
Whether you are watching videos on YouTube,
viewing DVDs, or simply enjoying the smooth
transition effects when you maximize/minimize
your windows, your graphics device is doing the
hard work behind the scenes.
companies: Intel, /, and  Corp. You can find your video card
manufacturer by referring to your computer’s manual, by looking for the
specifications of your computer’s model on the Internet, or by using the
command lspci in a terminal. e Ubuntu Soware Center houses a num-
ber of applications that can tell you detailed system information. SysInfo is
one such program that you can use to find relevant information about your
System devices. Ubuntu comes with support for graphics devices manufac-
tured by the above companies, and many others, out of the box. at means
you don’t have to find and install any drivers yourself, Ubuntu takes care of
it all.
Keeping in line with Ubuntu’s philosophy, the drivers that are used by
default for powering graphics devices are open source. is means that the
drivers can be modified by the Ubuntu developers and problems with them
can be fixed. However, in some cases a proprietary driver (restricted driver)
provided by the company may provide beer performance or features that
are not present in the open source driver. In other cases, your particular
device may not be supported by any open source drivers yet. In those
scenarios, you may want to install the restricted driver provided by the
manufacturer.
For both philosophical and practical reasons, Ubuntu does not install
restricted drivers by default but allows the user to make an informed choice.
Remember that restricted drivers, unlike the open source drivers for your
device, are not maintained by Ubuntu. Problems caused by those drivers

     .
will be resolved only when the manufacturer wishes to address them. To
see if restricted drivers are available for your system, go to System Settings,
then open Soware and Updates and go to the Additional Drivers tab. If
a driver is provided by the company for your particular device, it will be
listed there. You can simply click Activate to enable the driver. is process
requires an active Internet connection and it will ask for your password.
Once installation is complete you may have to reboot your computer to
finish activating the driver.
e Ubuntu developers prefer open source drivers because they allow Another useful resource is the official online
documentation (http://help.ubuntu.com), which
contains detailed information about various
graphics drivers and known problems. This
same documentation can be found by searching
for Help in the Dash search bar or by pressing
F1 on your keyboard.
any problem to be identified and fixed by anyone with knowledge within
the community. Ubuntu development is extremely fast and it is likely that
your device will be supported by open source drivers. You can use the

installing, or go online to the Ubuntu forums or to http://www.askubuntu.
com to ask about your particular device.
Setting up your screen resolution
One of the most common display related tasks is seing the correct screen
resolution for your desktop monitor or laptop.
Ubuntu correctly identifies your native screen resolution by itself and Displays are made up of thousands of tiny
pixels. Each pixel displays a different color,
and when combined they all display the image
that you see. The native screen resolution is a
measure of the amount of actual pixels on your
display.
sets it for you. However, due to a wide variety of devices available, some-
times it can’t properly identify your resolution.
To set or check your screen resolution, go to System Settings ‣ Displays.
e “Displays” window detects automatically the type of display and shows
your display’s name, size. e screen resolution and refresh rate is set to
the recommended value by Ubuntu. If the recommended seings are not to
your liking, you can change the same from the Resolution drop-down to
the resolution of your choice.
Adding an extra display
Sometimes, you may want to add more than one display device to your
desktop, or may want to add an external monitor to your laptop. Doing
this is quite simple. Whether it’s an extra monitor,  , or a projector,
Ubuntu can handle it all. Ubuntu supports the addition of multiple displays
by default, which is as easy as plug and play.
Ubuntu recognizes almost all the latest monitors, s and projectors
by default. Sometimes it may happen that your additional display is not
detected when you connect it to the machine. To resolve this, go to Sys-
tem Settings ‣ Displays and click on Detect Displays. is will detect the
monitors connected to the machine. is menu can also be found from the
Power Off menu on the top panel. You can also search for Displays at the
Dash search bar.
Now, there are two modes which you can enable for your displays. One
option is to spread your desktop across two or more monitors. is is par-
ticularly useful if you are working on multiple projects and need to keep
an eye on each of them at the same time. You can configure the screen to
be on any side of your primary screen i.e. to your right, your le or on the
top(particularly nice if you are working on a large screen i.e. a big monitor
or a TV connected to your - inch laptop); just move the screen on the

Connecting and using your printer
Ubuntu supports most new printers. You can add, remove, and change
printer properties by navigating to System Settings ‣ Printing. You can also
search for Printing from the Dash search bar. Opening Printing will display
the “Printing-localhost” window.
When you want to add a printer, you will need to make sure that it is
switched on, and plugged into your computer with a  cable or connected
to your network.
Adding a local printer
If you have a printer that is connected to your computer with a  cable
then this is termed a local printer. You can add a printer by clicking on the
Add Printer buon.
In the le hand pane of the “New Printer” window any printers that you
can install will be listed. Select the printer that you would like to install and
click Forward.

these should remind you of that particular printer so that you can choose
the right one to use when printing. Finally, click Apply.
Adding a network printer
Make sure that your printer is connected to your network either with an
Ethernet cable or via wireless and is turned on. You can add a printer by
clicking Add Printer. e “New Printer” window will open. Click the “+”
sign next to Network Printer.
If your printer is found automatically it will appear under Network
Printer. Click the printer name and then click Forward. In the text fields
you can now specify the printer name, description and location. Each of

Bluetooth
Bluetooth is a wireless technology that is widely used by different types of
devices to connect to each other. It is common to see a mouse or a keyboard
that supports Bluetooth. You can also find  devices, mobile phones,
headsets, music players and many other devices that can connect to your
desktops or laptop and let you transfer data, listen to music, or play games
as an example.
If your computer has Bluetooth support then you should be able to see
a Bluetooth icon on the top panel, usually on the le side of the volume
icon. If you click on the Bluetooth icon it will open a drop down menu with
choices to Turn on/off Bluetooth, to Turn on/off visibility of the device,
setup a access to a Bluetooth device and also access Bluetooth seings.
Figure 4.2: The Bluetooth applet menu.
e Bluetooth preferences can also be accessed from System Settings ‣
Bluetooth. If you want to connect(pair) a new device—for example, to have
a mobile phone send pictures or videos to your computer—click on the
Bluetooth icon on the top panel and select Setup new device….
Ubuntu will open a window for new device setup. When you click For-
ward, Ubuntu will show you how many Bluetooth devices are present near
your computer. e list of available devices might take a minute or so to
appear on the screen as your system scans for these devices. Each device
will be displayed as soon as it is found by Ubuntu. Once a device you’d like
to connect with appears in the list, click on it. en, choose a  number
by selecting PIN options.
ree predefined  numbers are available, but you can also create a When you pair two Bluetooth devices, you are

with Ubuntu.
Once the device has been paired, Ubuntu will open the “Setup com-
pleted” window. In Ubuntu, your computer is hidden by default for security
reasons. is means that your Ubuntu system can search other Bluetooth
devices, but others cannot find your Ubuntu system when they perform a
search on their own computer. If you would like to let another device find
your computer, you will have to explicitly allow your computer to be found.
To allow your computer to be found by other bluetooth devices, turn ’on’
the “Visibility of yourcomputername” from System Settings ‣ Bluetooth. You
can also click on the Bluetooth icon and click on Visible to turn on visibility
which will make your computer discoverable.
You can also add a fancy name for your Bluetooth-enabled Ubuntu sys-
tem by changing the text under Friendly Name.
Another feature present in the Bluetooth icon menu is “Send files to Android devices need to be paired at all times,
even while transferring files.device.” Use this option to send a file to a mobile phone without pairing
with the computer.

5 Software Management
Software management in Ubuntu
Installing soware in Ubuntu extends the functionality and usability of this
operating system. is chapter describes the way Ubuntu manages soware
installation and how it keeps all soware current.
Package management system
Ubuntu and various other Linux variants use a collection of soware tools
called a package management system, or package manager. A package man-
ager is a collection of tools that make installing, deleting, upgrading, and
configuring soware easy. A package management system has a database
of soware called a repository where individual soware is arranged into
a collection called a packages. ese packages, apart from the soware,
contain important information about the soware itself, such as the so-
ware’s name, description, version, name of the vendor, and a list of various
dependencies upon which the soware relies for proper installation.
Most other operating systems require a user to purchase commercial
soware (online or through a physical store) or search the Internet for
a free alternative (if one is available). e correct installation file must
then be verified for integrity, downloaded, and located on the computer,
followed by the user proceeding through a number of installation prompts
and options. A package management system removes the user interaction
from these steps and automates most, if not all, of the installation process.
Ubuntu comes with a package management system called Advanced
Packaging Tool or .
As discussed in Chapter : Working with Ubuntu, Ubuntu offers a wide
range of applications for your daily work. Ubuntu comes with a basic set
of applications for common tasks, like surfing the Internet, checking email,
listening to music, and organizing photos and videos. At times, you may
need an extra level of specialization. For example, you may want to retouch
your photos, run soware for your business, or play new games. In each of
these cases, you can search for an application, install it, and use it—usually
with no extra cost.
Figure 5.1: Software Center icon
By default, Ubuntu provides a centralized point with two different ways
to browse the repositories for searching, installing, and removing soware.
‣ Ubuntu Soware Center
‣ Command line apt-get
Ubuntu Soware Center makes searching, installing, and/or removing
applications easy and convenient; it is most oen the application manage-
ment system used by both beginning and expert Ubuntu users. We highly
recommend the Ubuntu Soware Center for searching, installing, and
removing applications, although you can still use the command-line appli-
cation apt-get or install and use the advanced application Synaptic Package
Manager. Since soware in Ubuntu is delivered in the form of packages,
soware installation becomes a one-click, one-step process when using the
Ubuntu Soware Center.

Using the Ubuntu Software Center
ere are numerous ways to install soware on an operating system. In
Ubuntu, the quickest and easiest way to find and install new applications is
through the Ubuntu Soware Center.
To start the application, click on the Dash and search for Ubuntu So-
ware Center.
Figure 5.2: You can install and remove applica-
tions from your computer using the Software
Center.
e Ubuntu Soware Center can be used to install applications available
in the official Ubuntu repositories. e Ubuntu Soware Center window has
four sections—a list of categories on the le, a banner at the top, a “What’s
New” panel below the top banner, then a “Recommended For You” panel,
and finally a “Top Rated” panel at the boom. Clicking on a category will
take you to a list of related applications. For example, the Internet category
contains the Firefox web browser application.
e featured areas highlight “What’s New” and “Top Rated” soware.
Each area shows different application icons. Just click an icon to get more
information on the application or to install it. To see all soware contained
in the area, click the More buon in the upper-right corner of each panel.
e three sections at the top represent your current view of the Soware
Center’s catalog. Click the All Soware buon to see all installable so-
ware, click the Installed buon to see a list of soware already installed on
your computer, and click History to see previous installations and deletions
organized by date.
Find your application
e Ubuntu Soware Center displays different sources in the “All Soware”
section. Clicking the arrow next to “All Soware” will show a list of in-
dividual sections. Selecting “Provided by Ubuntu” will show free, official
soware. “For Purchase” will show soware available to buy, and “Canoni-
cal Partners” will show soware from partners of Canonical, such as Adobe.
If you are looking for an application, you may already know its specific
name (for example,  Media Player), or you may just have a general
category in mind (for example, the Sound and Video category includes a

  
number of different soware applications, such as video converters, audio
editors, and music players).
To help you find the right application, you can browse the Soware Cen-
ter catalog by clicking on the category reflecting the type of soware you
seek. When you select a category, you will be shown a list of applications.
Some categories have sub-categories—for example, the Games category has
subcategories for Simulation and Card Games. To move through categories,
use the ba and forward buons at the top of the window.
As you view a category of soware, you’ll notice a search box in the
upper-right corner of the window. is search box can be used for specific
names or keyword searches within this category.
Figure 5.3: Searching for an application in the
Ubuntu Software Center.
Installing software
Once you have found an application you would like to try, installing it is
just one click away.
To install soware:
. Click the Install buon to the right of the selected package. If you would
like to read more about the soware package before installing it, first
click on More Info buon just below the selected soware. is will take
you to a short description of the application as well as a screenshot and
a web link when available. Related add-ons will be listed below the ap-
plication’s description. You can click Install from this screen as well. You
must be connected to the Internet in order to install soware through the
Ubuntu Soware Center. To learn how to set up your Internet connec-
tion, see Geing online.
. Aer clicking Install, enter your password into the authentication win-
dow. is is the same password you use to log in to your account. You
are required to enter your password whenever installing or removing
soware in order to prevent someone without administrator access from
making unauthorized changes to your computer. If you receive an Au-
thentication Failure message aer typing in your password, check that
you typed it correctly and try again.

Figure 5.4: Here, clicking on “Install” will
download and install the package “Stellarium.”
. Wait until the package is finished installing. During the installation
(or removal) of programs, you will see an animated icon of rotating
arrows to the right of the History buon at the top of the screen. is
animated icon is labelled Progress. If you like, you can go back to the
main browsing window and choose additional soware packages to be
installed by following the steps above. At any time, clicking the Progress
buon on the top will take you to a summary of all operations that are
currently processing. You can also click the X to cancel any operation
listed.
Once the Soware Center has finished installing an application, it is
ready to be used. You can start the newly installed application by going to
the Dash and typing the name of the application in the search bar.
Removing software
Removing applications is very similar to installing soware. First, find the
installed soware in the Ubuntu Soware Center. You can click on the
Installed buon to see all installed soware listed by categories. Scroll
down to the application you wish to remove. If you click on the arrow next
to the Installed buon, you will find a list of soware providers, which can
help you narrow your search. You can also enter keywords into the Search
field to quickly find installed soware, or you can search by date in the
History tab (more on History below).
To remove soware:
. Click the Remove buon to the right of the selected application.
. Enter your password into the authentication window. Similar to in-
stalling soware, removing soware requires your password to help
protect your computer against unauthorized changes. e package will
then be queued for removal and will appear under the progress section at
the top.
Removing a package will also update your menus accordingly.

Figure 5.5: Here, clicking on “Remove” will
remove the package “SuperTux 2.”
Software history
e Ubuntu Soware Center keeps track of past soware management in
the History section. is is useful if you wish to reinstall an application
previously removed and do not remember the application’s name.
ere are four buons in the history section—All Changes, Installations,
Updates, and Removals. If you click the arrow next to a day, a list of indi-
vidual packages will be shown, along with what was done with them and at
what time.
Software Recommendations
e Ubuntu Soware Center recommends soware based on the soware
already installed on your systems. When you enable recommendations,
a list of locally installed soware will be periodically sent to servers of
Canonical. Recommendations will appear in the same panel. If you want to
disable these recommendations, go to View ‣ Turn Oﬀ Recommendations.
Figure 5.6: You can turn on Software Rec-
ommendations via clicking on the Turn On
Recommendations button.
Figure 5.7: The “People Also Installed” section
shows applications installed by users who also
installed the application which you are about to
install.
Managing additional software
Although the Ubuntu Soware Center provides a large library of appli-
cations from which to choose, only those packages available within the
oﬃcial Ubuntu repositories are listed. At times, you may be interested in
a particular application not available in these repositories. It is important

     .
to understand alternative methods for accessing and installing soware in
Ubuntu, such as downloading an installation file manually from the Inter-
net, or adding extra repositories. First, we will look at how to manage your
repositories through Soware & Updates.
Software Sources
e Ubuntu Soware Center lists only those applications that are available
in your enabled repositories. Repositories can be added or removed through
the Soware & Updates application. You can open Soware & Updates from
the Ubuntu Soware Center. Simply go to Edit ‣ Soware Sources… or open
the  (le Alt key) and search for “sources.”
Figure 5.8: The Software & Updates program
enables you to add, remove and manage
package repositories.
Managing the official repositories
When you open Soware & Updates, you will see the Ubuntu Soware tab
where the first four options are enabled by default.
Canonical-supported free and open-source soware (main) is repository
contains all the open-source packages maintained by Canonical.
Community-maintained free and open-source soware (universe) is reposi-
tory contains all the open-source packages developed and maintained by
the Ubuntu community.
Proprietary drivers for devices (restricted) is repository contains propri-
etary drivers which may be required to utilize the full capabilities of
some of your devices or hardware.
Figure 5.9: Drivers can be installed or removed
via the Additional Drivers application.

  
Soware restricted by copyright or legal issues (multiverse) is repository
contains soware possibly protected from use in some states or countries
by copyright or licensing laws. By using this repository, you assume
responsibility for the usage of any packages that you install.
Source code is repository contains the source code used to build soware
packages from some of the other repositories. Building applications from
source is an advanced process for creating packages, and usually only
concerns developers. e Source code option should not be selected
unless you have experience with building applications from source.
Selecting the best software server
To distribute applications and soware, Ubuntu grants permission to many
servers all across the world to act as official mirrors to host an exact copy of
all the files contained in the official Ubuntu repositories.
When selecting a server, you may want to consider the following:
Distance to server. is will affect the speed you can achieve with the file
server—the closer the server to your location, the faster the potential
connection.
Internet Service Provider. Some Internet service providers offer low-cost or
unlimited free downloads from their own servers.
ality of server. Some servers may only offer downloads at a capped
speed, limiting the rate at which you can install and update soware on
your computer.
Ubuntu will automatically choose an appropriate server while installing.
It is recommended these seings not be changed unless your physical loca-
tion significantly changes or if you feel a higher speed should be achieved
by your Internet connection. e guide below will help in choosing an
optimal server.
Ubuntu provides a tool for selecting the server that provides the fastest
connection with your computer.
Figure 5.10: You can use automatic selection or
choose a server manually.
. Click the dropdown box next to “Download from:” in the Soware &
Updates window.
. Select “Other…” from the list.
. In the “Choose a Download Server” window, click the Select Best Server
buon in the upper-right. Your computer will now aempt a connection
with all the available servers, then select the one with the fastest speed.
If you are happy with the automatic selection, click Choose Server to
return to the Soware & Updates window.

     .
If you are not happy with the automatic selection or prefer not to use
the tool, the fastest server is oen the closest server to you geographically.
In this case, simply choose “Other” then find the nearest location to your
location. When you are happy with the selection, click Choose Server to
return to the Soware & Updates window.
If you do not have a working Internet connection, updates and programs
can be installed from the installation media itself by inserting your media
and clicking the box under “Installable from /.” Once this box
is checked, the media within the / drive will function as an
online repository, and the soware on the media will be installable from the
Ubuntu Soware Center.
Adding more software repositories
Ubuntu makes it easy to add additional third-party repositories to your list
of soware sources. e most common repositories added to Ubuntu are
called s. A  is a Personal Package Archive. ese are online reposito-
ries used to host the latest versions of soware packages, digital projects,
and other applications. s allow you to install soware packages that are
not available in the official repositories. s also allow you to automati-
cally be notified whenever updates for these packages are available.
If you know the web address of a ’s Launchpad site, adding it to your
list of soware sources is relatively simple. To do so, you will need to use
the Other Soware tab in the “Soware & Updates” window.
On the Launchpad site for a , you will see a heading to the le called
“Adding this PPA to your system.” Underneath will be a short paragraph
containing a unique  in the form of ppa:test-ppa/example. Highlight this
 by selecting it with your mouse, then right-click and select Copy.
Figure 5.11: This is an example of the Launch-
pad page for the Ubuntu Tweak PPA. Ubuntu
Tweak is an application that is not available
in the official Ubuntu repositories. However,
by adding this PPA to your list of software
sources, it will be easy to install and update this
application through the Software Center.
Return to the “Soware & Updates” window, and in the Other Soware
tab, click Add… at the boom. A new window will appear, and you will
see the words “Apt line:” followed by a text field. Right-click on the empty
space in this text field and select Paste. You should see appear the  you
copied from the ’s Launchpad site earlier. Click Add Source to return
to the “Soware & Updates” window. You will see a new entry has been
added to the list of sources in this window with a selected check box in
front (meaning it is enabled).
If you click Close in the boom right corner of this window, a message

  
will appear informing you that “e information about available soware
is out-of-date.” is is because you have just added a new repository to
Ubuntu, and it now needs to connect to that repository and download a list
of the packages it provides. Click Reload, and wait while Ubuntu refreshes
all of your enabled repositories (including this new one you just added).
When it has ﬁnished, the window will close automatically.
Congratulations, you have just added a  to your list of soware
sources. You can now open the Ubuntu Soware Center and install appli-
cations from this  in the same way you previously installed applications
from the default Ubuntu repositories.
Manual software installation
Although Ubuntu has extensive soware available, you may want to man-
ually install a soware package not available in the repositories. If no 
exists for the soware, you will need to install it manually. Before you
choose to do so, make sure you trust the package and its maintainer.
Packages in Ubuntu have a .deb extension. Double-clicking a package
will open an overview page in the Ubuntu Soware Center which will give
you more information about that package.
e overview provides technical information about that package, a
website link (if applicable), and the option to install. Clicking Install will
install the package just like any other installation in the Ubuntu Soware
Center.
Figure 5.12: Installing .deb ﬁles manually using
software center.
Updates and upgrades
Ubuntu also allows you to decide how to manage package updates through
the Updates tab in the Soware & Updates window.
Ubuntu updates
In this section, you are able to specify the kinds of updates you wish to
install on your system. e type of update usually depends upon your

     .
preferences with regards to system stability versus having access to the
latest developments.
Figure 5.13: You can update installed software
by using the Software Updater application in
Ubuntu.
Important security updates (saucy-security) ese updates are highly rec-
ommended to ensure your system remains as secure as possible. ese
updates are enabled by default.
Recommended updates (saucy-updates) ese updates are not as important
in keeping your system secure. Rather, updates listed in this section will
keep your soware updated with the most recent bug fixes or minor
updates that have been tested and approved. is option is also enabled
by default.
Pre-released updates (saucy-proposed) is option is for those who would
rather remain up-to-date with the very latest releases of applications
at the risk of installing an update that has unresolved bugs or conflicts.
Note that it is possible you will encounter problems with these updated
applications, therefore, this option is not enabled by default.
Unsupported updates (saucy-backports) ese are updates that have not
yet been fully tested and reviewed by Canonical. Some bugs may occur
when using these updates, and so this option is also not enabled by
default.
Automatic updates
e middle section of this window allows you to customize how your sys-
tem manages updates, such as the frequency with which it checks for new
packages, as well as whether it should install important updates right away
(without asking for your permission), download them only, or just notify
you about them.
Release upgrade
At the boom of the Updates tab in the Soware & Updates window, you
will see a dropdown box labeled Notify me of a new Ubuntu version:. is
option allows you to tell Ubuntu how you would like to handle release
updates. is dropdown box contains the following options for notification:
Never Choose this option if you would rather not be notified about any
new Ubuntu releases.
For any new version Choose this option if you always want to have the
latest Ubuntu release, regardless of whether it is a long-term support
release or not. is option is recommended for normal home users.

  
For long-term support versions Choose this option if you need a release
that will be more stable and have support for a longer time. If you use
Ubuntu for business purposes, you may want to consider selecting this
option.
Canonical will release a new version of the Ubuntu operating system
every six months. Most every release is called a normal release. However,
every fourth release—or every  months—Canonical releases a long-
term support () version of the operating system. Long-term support
releases are intended to be the most stable releases available and are
supported for a longer period of time. Ubuntu . is a normal release.
Ubuntu . will be an LTS release.

6 Advanced Topics
Ubuntu for advanced users
To this point, we’ve provided detailed instructions on geing the most from
Ubuntu’s basic features. In this chapter, we’ll detail some of Ubuntu’s more
advanced features—like the terminal, a powerful utility that can help you
accomplish tasks without the need for a graphical user interface (). We’ll
also discuss some advanced security measures you can implement to make
your computer even safer.
is chapter has been wrien with advanced users in mind. If you’re
new to Ubuntu, don’t feel as though you’ll need to master these topics to
get the most out of your new soware (you can easily skip to the next chap-
ter without any adverse impact to your experience with Ubuntu). However,
if you’re looking to expand your knowledge of Ubuntu, we encourage you
to keep reading.
Introduction to the terminal
roughout this manual, we have focused primarily on the GUI. In order
to fully realize the power of Ubuntu, you will need to learn how to use the
terminal.
What is the terminal?
Most operating systems, including Ubuntu, have two types of user inter-
faces. e first is a GUI. is is the desktop, windows, menus, and toolbars
you click to get things done. e second, much older type of interface is the
command-line interface ().
e terminal is Ubuntu’s CLI. It is a method of controlling some aspects
of Ubuntu using only commands that you type on the keyboard.
Why would I want to use the terminal?
You can perform most day-to-day activities without ever needing to open
the terminal. However, the terminal is a powerful and invaluable tool that
can be used to perform many useful tasks you might not be able to accom-
plish with a . For example:
‣ Troubleshooting any difficulties that may arise when using Ubuntu
sometimes requires you to use the terminal.
‣ A command-line interface is sometimes a faster way to accomplish a
task. For example, it is oen easier to perform operations on many files
concurrently using the terminal.
‣ Learning the command-line interface is the first step towards more
advanced troubleshooting, system administration, and soware develop-
ment skills. If you are interested in becoming a developer or an advanced
Ubuntu user, knowledge of the command-line is essential.

Opening the terminal
You can open the terminal by clicking Dash then searching for word “term”.
You’ll see an application named terminal. Click on this application to open
a terminal. Alternatively, you can open the terminal by hiing Ctrl+Alt+T
simultaneously.
e terminal gives you access to what is called a shell. When you type
a command in the terminal, the shell interprets this command, resulting in
the desired action. Different types of shells accept slightly different com-
mands. e most popular is called “bash,” and is the default shell in Ubuntu.
When the terminal window opens, it will be largely blank with the excep-
tion of some text at the top le of the screen, followed by a blinking block,
known as a cursor. is text is your prompt—it displays, by default, your
login name and your computer’s name, followed by the current directory.
e tilde (~) means that the current directory is your home directory. Fi-
nally, the blinking block is called the cursor—this marks where text will be
entered as you type.
To test a terminal command, type pwd and press Enter. e terminal
should display /home/yourusername. is text is called the “output.” You
have just used the pwd (print working directory) command, which outputs
(displays) the current directory.
Figure 6.1: The default terminal window allows
you to run hundreds of useful commands.
All commands in the terminal follow the same approach: Type a com-
mand, possibly followed by some parameters, and press Enter to perform
the specified action. Parameters (also called switches) are extra segments
of text, usually added at the end of a command, that change how the com-
mand itself is interpreted. ese usually take the form of -h or --help, for
example. In fact, --help can be added to most commands to display a short
description of the command, as well as a list of any other parameters that
can be used with that command.
Oen, some type of output will be displayed confirming the action was
completed successfully, although this can depend on the command being
executed. For example, using the cd command to change your current direc-
tory (see above) will change the prompt but will not display any output.
e rest of this chapter covers some very common uses of the termi-
nal. roughout the second part of this manual, we will continue to refer
to the command line, particularly when discussing steps involved in trou-
bleshooting as well as when describing more advanced management of your
computer.

Ubuntu file system structure
Ubuntu uses the Linux file system, which is based on a series of folders
in the root directory. ese folders contain important system files that
cannot be modified unless you are running as the root user or use sudo. is
restriction exists for both security and safety reasons; computer viruses will
not be able to change the core system files, and ordinary users should not
be able to accidentally damage anything vital.
Figure 6.2: Some of the most important
directories in the root file system.
We begin our discussion of the Ubuntu file system structure at the top
—also known as the root directory—as denoted by /. e root directory
contains all other directories and files on your system. Below the root
directory are the following essential directories:
/bin and /sbin Many essential system applications (equivalent to C:Windows).
/etc System-wide configuration files.
/home Each user will have a subdirectory to store personal files (for
example, /home/yourusername) which is equivalent to C:Users or
C:Documents and Settings in Microso Windows.
/lib Library files, similar to .dll files on Windows.
/media Removable media (s and  drives) will be mounted in this
directory.
/root is contains the root user’s files (not to be confused with the root
directory).
/usr Pronounced “user,” it contains most program files (not to be con-
fused with each user’s home directory). is is equivalent to C:Program
Files in Microso Windows.
/var/log Contains log files wrien by many applications.
Every directory has a path. e path is a directory’s full name—it de-
scribes a way to navigate the directory from anywhere in the system.
For example, the directory /home/yourusername/Desktop contains all the
files that are on your Ubuntu desktop. It can be broken down into a handful
of key pieces:
‣ /—indicates that the path starts at the root directory
‣ home/—from the root directory, the path goes into the home directory
‣ yourusername/—from the home directory, the path goes into the you-
rusername directory
‣ Desktop—from the yourusername directory, the path ends up in the
Desktop directory

     .
Every directory in Ubuntu has a complete path that starts with the / (the
root directory) and ends in the directory’s own name.
Directories and files that begin with a period are hidden. ese are usu-
ally only visible with a special command or by selecting a specific option.
In the Files file manager, you can show hidden files and directories by
selecting the View Options buon located in the upper-right of the win-
dow. is will show a dropdown list of options. Select Show Hidden Files.
Hidden files can also be shown by simply pressing Ctrl+H in the Files file
manager. If you are using the terminal, then you would type ls -a and
press Enter to see the hidden files and directories. ere are many hidden
directories in your home folder used to store program preferences. For ex-
ample, /home/yourusername/.thunderbird stores preferences used by the
underbird mail application.
Mounting and unmounting removable devices
Any time you add storage media to your computer—an internal or external
hard drive, a  flash drive, a —it needs to be mounted before it is
accessible. Mounting a device means to associate a directory name with the
device, allowing you to navigate to the directory to access the device’s files.
When a device, such as a  flash drive or a media player, is mounted in
Ubuntu, a folder is automatically created for it in the media directory, and
you are given the appropriate permissions to be able to read and write to
the device.
Most file managers will automatically add a shortcut to the mounted
device in the side bar of your home folder or as a shortcut directly on the
desktop so that the device is easily accessible. You shouldn’t have to physi-
cally navigate to the media directory in Ubuntu unless you choose to do so
from the command line.
When you’ve finished using a device, you can unmount it. Unmounting a
device disassociates the device from its directory, allowing you to eject it. If
you disconnect or remove a storage device before unmounting it, you may
lose data.
Securing Ubuntu
Now that you know a bit more about using the command line, we can use it
to make your computer more secure. e following sections discuss various
security concepts, along with procedures for keeping your Ubuntu running
smoothly, safely, and securely.
Why Ubuntu is safe
Ubuntu is secure by default for a number of reasons:
‣ Ubuntu clearly distinguishes between normal users and administrative
users.
‣ Soware for Ubuntu is kept in a secure online repository containing no
false or malicious soware.
‣ Open-source soware like Ubuntu allows security flaws to be easily
detected.
‣ Security patches for open-source soware like Ubuntu are oen released
quickly.

  
‣ Many viruses designed to primarily target Windows-based systems do
not affect Ubuntu systems.
Just because Ubuntu implements strong security model by default doesn’t
mean the user can “throw caution to the wind.” Care should always be
taken when downloading files, opening email, and browsing the Internet.
Using a good antivirus program is warranted as well.
Basic security concepts
e following sections discuss basic security concepts—like file permissions,
passwords, and user accounts. Understanding these concepts will help you
in securing your computer.
Permissions
In Ubuntu, files and folders can be set up so that only specific users can
view, modify, or run them. For instance, you might wish to share an impor-
tant file with other users, but do not want those users to be able to edit the
file. Ubuntu controls access to files on your computer through a system of
“permissions.” Permissions are seings configured to control exactly how
files on your computer are accessed and used.
To learn more about modifying permissions, visit https://help.ubuntu.
com/community/FilePermissions.
Passwords
You should use a strong password to increase the security of your computer.
Your password should not contain names, common words, or common
phrases. By default, the minimum length of a password in Ubuntu is four
characters. We recommend a password with more than the minimum num-
ber of characters. A password with a minimum of eight characters which
includes both upper and lower case leers, numbers, and symbols is consid-
ered strong.
Locking the screen
When you leave your computer unaended, you may want to lock the
screen. Locking your screen prevents another user from using your com-
puter until your password is entered. To lock the screen:
‣ Click the session menu icon in the right corner of the top panel, then
select Lo, or
‣ press Ctrl+Alt+L to lock the screen. is keyboard shortcut can be
changed by going to Session Indicator ‣ System Settings… ‣ Keyboard ‣
Shortcuts and then selecting System from the list in the le column and
clicking on Lo Screen in the right column.
Users and groups
User accounts
When Ubuntu is installed, it is automatically configured for use by a single
user. If more than one person will use the computer, each person should
have his or her own user account. is way, each user can have separate

     .
seings, documents, and other files. If necessary, you can also protect files
from being viewed or modified by users without administrative privileges.
Like most operating systems, Ubuntu allows you to create separate user
accounts for each person. Ubuntu also supports user groups, which allows
you to administer permissions for multiple users at the same time.
Every user in Ubuntu is a member of at least one group. At a bare min-
imum, the user of the computer has permissions in a group with the same
name as the user. A user can also be a member of additional groups. You
can configure some files and folders to be accessible only by a user and a
group. By default, a user’s files are only accessible by that user, and system
files are only accessible by the root user.
Figure 6.3: Add, remove and change the user
accounts.
Managing users
If the account you are using is an administrator account, you can manage
users and groups using the Users and Groups administration application.
To find this application, click Session Indicator ‣ System Settings… ‣ User
Accounts. en click the Unlo buon and enter your password to unlock
the user seings. Next, select the user that you want to modify from the list.
en click on the element that you want to change.
Adding a user Click the + buon underneath the list of the current user
accounts. A window will appear with three fields. e Account Type field
contains a list of user account types. Take care in determining what type
of account to assign a user. An Administrator has full access to all areas
of Ubuntu, whereas the Standard account type is more limited. e Full
Name field contains a friendly display name. e Username field is for the
actual username. As you enter the user’s full name, the Username field will
automatically fill with a lowercase, no space version of the user’s full name.
If you prefer to use a different username for this user, highlight the existing
username and type in the username of your choice. Once all fields are
filled in, click Add. A new dialog box will appear showing the user account
details. New accounts are disabled by default. To enable an account, click
the Account disabled field next to the Password label. A new window will
appear allowing you to set the password for the new user.
At the top of the new window is a dropdown menu next to the label
Action. By default, the “set a password now” option will be automatically
selected. You may also choose “log in without a password”, however, this
is not advised as the account will be available to anyone. e final option,
“enable this account” is available once a password has been set. Using this

  
option allows an administrator to enable or disable an account without
losing the password.
Ubuntu provides a way to create a secure password by clicking the gears
buon located inside of the New password field. A random sequence of
numbers, leers, and symbols will be entered into this field. You can also
simply enter a password of your choosing by entering it into the New
password field. en, re-enter this same password into the space next to
Confirm password.
Ubuntu enforces the password policies on this screen, so pay aention to the
status information located between the New password and Confirm password
fields for information about the password you’re seing. If there are problems
with the password, Ubuntu will tell you what is wrong with the password and
will prevent you from entering the same password into the Confirm password
field until the new password meets the requirements.
Modifying a user Click on the name of a user in the list of users, then click
on the text entry next to any of the following options:
‣ Account type:
‣ Language:
‣ Password:
‣ Automatic Login:
You may also change the username by clicking on the username at the top
and entering a new name.
Deleting a user Select a user from the list and click -. Ubuntu will deacti-
vate the user’s account, and you can choose whether to remove the user’s
home folder or leave it in place. If a user is removed and the user’s files re-
main, the only user who can access the files are the root user—also known
as the superuser—or anyone associated with the file’s group.
Managing groups
Group management is accomplished through the command line (Terminal)
or by adding third-party applications (the laer is beyond the scope of this
manual). You will find more information in the section below titled “Using
the command line”.
Adding a group To add a group, type sudo addgroup groupname and press
Enter, replacing groupname with the name of the group you wish to add.
For example, sudo addgroup ubuntuusers will add the group ubuntuusers
to the list of groups.
Modifying a group To alter the users in an existing group, type sudo
adduser username groupname to add a user, or sudo deluser username
groupname and press Enter to remove a user replacing username and group-
name in these commands with the actual user and group name with which
you’re working.
Deleting a group To delete a group, type sudo delgroup groupname and
press Enter, replacing groupname with the name of the group you wish to
delete.

     .
Applying groups to files and folders
To change the group associated with a file or folder, open the Files file man-
ager and navigate to the appropriate file or folder. en, either select the
folder and then click the gears buon in the upper-right of the window and
choose Properties, or right-click on the file or folder and select Properties.
In the Properties dialog window, click on the Permissions tab and select the
desired group from the Groups drop-down list. en close the window.
Using the command line
You can also modify user and group seings via the command line, but
we recommend you use the graphical method above unless you have a
good reason to use the command line. For more information on using the
command line to modify users and groups, see the Ubuntu Server Guide at
https://help.ubuntu.com/./serverguide/user-management.html.
System updates
Good security happens with an up-to-date system. Ubuntu provides free
soware and security updates. You should apply these updates regularly.
See Updates and upgrades to learn how to update your Ubuntu computer
with the latest security updates and patches.
Trusting third party sources
Normally, you will add applications to your computer via the Ubuntu So-
ware Center which downloads soware from the Ubuntu repositories as
described in Chapter : Soware Management. However, it is occasionally
necessary to add soware from other sources. For example, you may need
to do this when an application is not available in the Ubuntu repositories or
when you need a version of soware newer than what is currently in the
Ubuntu repositories.
Additional repositories are available from sites such as http://www.
getdeb.net and Launchpad s which can be added as described in So-
ware Sources. You can download the  packages for some applications
from their respective project sites on the Internet. Alternatively, you can
build applications from their source code.
Using only recognized sources, such as a project’s site,  or various
community repositories (such as http://www.getdeb.net), is more secure
than downloading applications from an arbitrary (and perhaps less rep-
utable) source. When using a third party source, consider its trustworthi-
ness, and be sure you know exactly what you’re installing on your com-
puter.
Firewall
A firewall is an application that protects your computer against unautho-
rized access by people on the Internet or your local network. Firewalls
block connections to your computer from unknown sources. is helps
prevent security breaches.
Uncomplicated Firewall () is the standard firewall configuration pro-
gram in Ubuntu. It runs from the command line, but a program called Gufw
allows you to use it with a graphical user interface . See Chapter :
Soware Management to learn more about installing the Gufw package.

  
Once Gufw is installed, start Gufw by clicking Dash ‣ Applications ‣
Firewall configuration. To enable the firewall, select the Enable option. By
default, all incoming connections are denied. is seing should be suitable
for most users.
If you are running server soware on your Ubuntu system (such as a
web server, or an  server), then you will need to open the ports these
services use. If you have no need to run any server applications or services,
you will likely not need to open any additional ports.
To open a port click on the Add buon. For most purposes, the Precon-
figured tab is sufficient. Select Allow from the first box and then select the
program or service required.
e Simple tab can be used to allow access on a single port, and the
Advanced tab can be used to allow access on a range of ports.
Encryption
You may wish to protect your sensitive personal data—for instance, finan-
cial records—by encrypting it. Encrypting a file or folder essentially “locks”
that file or folder by encoding it with an algorithm that keeps it scrambled
until it is properly decoded with a password. Encrypting your personal data
ensures that no one can open your personal folders or read your private
data without your authorization through the use of a private key.
Ubuntu includes a number of tools to encrypt files and folders. is
chapter will discuss two of them. For further information on using en-
cryption with either single files or email, see Ubuntu Community Help
documents at https://help.ubuntu.com/community.
Home folder
When installing Ubuntu, it is possible to encrypt a user’s home folder. See
Chapter : Installation for more on encrypting the home folder.
Private folder
If you have not chosen to encrypt a user’s entire home folder, it is possible
to encrypt a single folder—called Private—in a user’s home folder. To do
this, follow these steps:
. Install the ecryptfs-utils soware package from the Ubuntu Soware
Center. (For more information about the Soware Center, review Using
the Ubuntu Soware Center.)
. Use the terminal to run ecryptfs-setup-private to set up the private
folder.
. Enter your account’s password when prompted.
. Either choose a mount passphrase or generate one.
. Record both passphrases in a safe location. ese are required if you ever
have to recover your data manually.
. Log out and log back in to mount the encrypted folder.
Aer the Private folder has been set up, any files or folders in it will
automatically be encrypted.
If you need to recover your encrypted files manually see https://help.

Running Windows Programs on Ubuntu
As many Windows users will know, some programs that you can use on a
Windows system cease to work on Ubuntu. For example, LibreOffice works
on both Windows and Ubuntu systems, but Microso Office works only on a
Windows system. Since many Windows users who use Ubuntu want all of
their Windows programs back, many programmers have worked together to
create Wine. Wine is an acronym for “Wine Is Not an Emulator”.
is section will discuss what Wine is, and how to use it on your Ubuntu
installation. For recent information about Wine, please visit the official
Wine website at http://www.winehq.org.
What is Wine?
Wine is a background application that allows Linux and Mac users to install
and run Windows programs on their system. While not every Windows
program is compatible with Wine, many programs seem to be completely
compatible with Wine while running on Linux or Mac OS. For example,
Microso Office may not be compatible without installing additional com-
ponents (such as Microso.NET Framework .). e current stable version
of Wine is ., and the most recent development version is ...
Installing Wine
To install Wine Version ., follow the following steps:
If you have a previous version of Wine installed, uninstall Wine before continuing
using the command, sudo apt-get remove --purge wine1.* winetricks &&
sudo apt-get autoremove
. Open the terminal and type: sudo apt-add-repository ppa:ubuntu-
wine/ppa. is will install the Official Wine .
. Aer the terminal has finished installing the Wine , type: sudo apt-
get update. is will update the  list.
. Once the terminal has finished refreshing the  list, type: sudo apt-
get install -y wine1.6 winetricks. is will install Wine . and
Winetricks. Winetricks is a soware center for Wine, and is, in most
cases, optional.
Figure 6.4: The Terminal showing the installa-
tion of the Wine PPA.
During the installation of Wine and Winetricks, you will have to ac-
cept the Microso End User License Agreement and the Microso Core

  
Fonts License Agreement so that the Microso fonts and native ﬁles can be

Please Note: It is recommended to reboot your system aer installing
Wine and Winetricks, although this is not always required.
Installing Wine (Alternative)
For an alternative installation of Wine . (which does not involve the
terminal), follow these steps:
If you have a previous version of Wine installed, uninstall Wine before contin-
uing by opening the Ubuntu Soware Center, going to the Installed menu, and
selecting and uninstalling the version of Wine you have installed. (EX. Wine.,
Wine.)
. Open the Ubuntu Soware Center and go to the Application Menu.
. Select Edit ‣ Soware Sources….
. When a pop-up appears, enter your password to ensure that any and all
changes have your approval. en, click OK.

typed your password correctly. On the top of the window, there will be
a row of tabs. Click on the second tab, Other Soware. Click on this
menu.

application in the Ubuntu Soware Center.
During the installation of Wine and Winetricks, the Soware Center
will probably freeze. While the Soware Center is frozen, a new window,
that opened underneath the Soware Center’s window is waiting for you to
accept the Microso End User License Agreement and the Microso Core
Fonts License Agreement so that the Microso fonts and native files can be
installed. In this window, titled “Debconf on your-computer” (Replace your-
computer with your computer’s name.), the Microso Core Fonts EULA
will be shown. To accept the Microso Core Fonts EULA, check the Do you
accept the EULA license terms? checkbox and click the Forward buon.
dialog opened in the Software Center.
It is recommended to reboot your system aer installing Wine and
Winetricks, although this is not always required.
Configuring Wine
Wine ./.. contains many features that will change the look and feel
of the Windows applications you are trying to run. For example, you can
change the theme of the Windows interface, and what version of Windows
you would like to run (from Windows . to Windows ).
To change these seings, open the Dash and search for Configure Wine.
en, open the application.
Application Tab In the Application tab, you can change the way Wine
runs applications. Some Windows programs work only for specific versions
of Windows. is feature allows you to change the version of Windows
Wine will run as for a specific application, or for all of them to run under
one version.
Libraries Tab In the Libraries tab, you can change core Windows files,
to suit your needs. Many Windows programs install  files, or Dynamic
Link Libraries. ese files contain all of the information needed for an
application to work on a Windows system. Many  files are needed for

In this feature, you may edit or replace existing  files. is allows you to
change the Windows System files, to suit you needs.
ese files should not be edited. ese are core files needed for Wine to run
correctly. Only edit these files if you have to.
Graphics Tab In the Graphics tab, you can change the look and feel of
how Wine runs. You can make Wine emulate a Virtual Desktop (this feature
opens a new window that will contain any Windows application that is
currently running while this option is in effect), how the applications look,
and what resolution to run the application in.
Desktop Integration Tab In the Desktop Integration tab, you can change
the way buons, menus, and other elements appear in an application. Each
version of Windows has brought its own unique visual style for its ap-
plications. In this feature, you can install and change the applied theme.
In this tab, you can also change major file folders. For example, while
using Ubuntu, your picture folder is located at /home/user/Pictures/
but in Windows, your picture folder is located at C:Documents and Set-
tingsUserMy DocumentsMy Pictures or C:UsersUserMy Pictures.
is feature allows you tell Wine where your folders are, for quick refer-
ence.
Drives Tab In the Drives tab, you can manage the connected drives that
Wine will be able to access. Unlike Ubuntu, Windows applies a Drive Leer
to each drive. is leer identifies the drive. For example, on every Win-
dows system, the C: drive is the core drive. It contains all of the needed files
for the operating system to work. e C: drive is the equivalent to root (File
System, or / ) in Ubuntu. is feature allows you to change the drive leers
for any drive, or add a drive leer for a specific folder in your file system, or
for a  drive.
Audio Tab In the Audio tab, you can change the audio seings. is fea-
ture allows you to change the audio source that Wine will use for Windows
applications (speakers, microphones, etc.).

     .
About Tab In the About tab, you can see the current Wine version you
have installed, including Wine’s note to all users. is feature also allows
you to add a Name and Company Name to the Windows information. Ap-
plications use this information to identify you by name.
Microsoft .NET Framework and Wine
Microso has created many programs that are needed to run commonly
used applications, Microso .NET Framework being the most common. .NET
Framework is needed to run most of the newer applications created by
Microso, and by other companies as well. Wine is not fully supported by
all versions of .NET, but is compatible with most versions. Here is a list of
.NET versions, and their compatibility with Wine:
‣ .NET Framework .
‣ .NET Framework .
‣ .NET Framework .* * This framework has known issues running
under Wine and is, in most cases, installable and
stable enough to use for most applications.
‣ .NET Framework .*
‣ .NET Framework .
‣ .NET Framework .
‣ .NET Framework .*
‣ .NET Framework ..** ** This framework has not been tested using a
current version of Wine running on Ubuntu, so it
is unknown if it will be compatible or not. Use at
your own risk.
For some of the most recent .NET Frameworks to work properly, you
may have to install Wine ... To install Wine .., open the Terminal, and
key sudo apt-get install -y wine1.7.

7 Troubleshooting
Resolving problems
Sometimes things may not work as they should. Luckily, problems encoun-
tered while working with Ubuntu are oen easily fixed. is chapter is
meant as a guide for resolving basic problems users may encounter while
using Ubuntu. If you need any additional help beyond what is provided
in this chapter, take a look at other support options that are discussed in
Finding additional help and support later in this book.
Troubleshooting guide
e key to effective troubleshooting is to work slowly, complete all of the
troubleshooting steps, and to document the changes you made to the utility
or application you are using. is way, you will be able to undo your work,
or give fellow users the information about your previous aempts—the
laer is particularly helpful in cases when you look to the community of
Ubuntu users for support.
Ubuntu fails to start after I’ve installed Windows
Occasionally you may install Ubuntu and then decide to install Microso
Windows as a second operating system running side-by-side with Ubuntu.
is is supported in Ubuntu, but you might also find aer installing Win-
dows that you will no longer be able to start Ubuntu.
When you first turn on your computer, a “bootloader” is responsible for
initiating the start of an operating system, such as Ubuntu or Windows.
When you installed Ubuntu, you automatically installed an advanced boot- A bootloader is the initial software that loads
the operating system when the computer is
powered up.
loader called .  allows you to choose between the various operat-
ing systems installed on your computer, such as Ubuntu, Windows, Solaris,
or Mac  . If Windows is installed aer Ubuntu, the Windows installation
removed  and replaced the bootloader with it’s own. As a result, you
can no longer choose an operating system to use. You can restore  and
regain the ability to choose your operating system by following the steps
below, using the same  you used to install Ubuntu.
First, insert your Ubuntu  into your computer and then restart the
computer, making sure to instruct your computer to boot from the 
drive and not the hard drive (see Chapter : Installation). Next, choose your
language (e.g., English) and select Try Ubuntu. Once Ubuntu starts, click
on the top-most icon in the Launcher (the Dash icon). en, search for
Terminal using the search box. en, select Terminal in the search results
(or press Ctrl+Alt+T). A window should open with a blinking prompt line.
Enter the following, and press the Enter key:
$ sudo fdisk -l

Boot column, your computer is booting to /dev/sda2 (where Windows is
located). We need to fix this by telling the computer to boot to the Linux

To do this, create a place to connect your existing Ubuntu installation
with your temporary troubleshooting session:
$ sudo mkdir /mnt/root
Next, link your Ubuntu installation and this new folder:
$ sudo mount /dev/sda1 /mnt/root
If you’ve done this correctly, then you should see the following:
$ ls /mnt/root
bin dev home lib mnt root srv usr
boot etc initrd lib64 opt sbin sys var
cdrom initrd.img media proc selinux tmp vmlinuz
Now, you can reinstall :
$ sudo grub-install --root-directory=/mnt/root /dev/sda
Installation finished. No error reported.
This is the contents of the device map /boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script grub-install.

$ sudo umount /mnt/root
Finally, remove the Ubuntu disc from your  drive, reboot your
computer, and then start enjoying your Ubuntu operating system once
again.
is guide may not work for all Ubuntu users due to differences in the

RecoveringUbuntuAfterInstallingWindows.
I forgot my password
If you forgot your password in Ubuntu, you will need to reset it using the
“Recovery mode.”
To start the Recovery mode, shut down your computer and then start
again. As the computer starts up, press Shift. Select the Recovery mode
option using the arrow keys on your keyboard. Recovery mode should be
under the heading Advanced Options in the list.
Wait until Ubuntu starts up—this may take a few minutes. Once booted,
you will not be able to see a normal login screen. Instead, you will be pre-
sented with the Recovery Menu. Select root using the arrow keys and press
Enter.
You will now be at a terminal prompt:
root@ubuntu:~#

 
Figure 7.1: This is the grub screen in which you
can choose recovery mode.
To reset your password, enter:
# passwd username
Replace “username” above with your username, aer which Ubuntu will
prompt you for a new password. Enter your desired password, press the
Enter key, and then re-type your password again, pressing Enter again
when done. (Ubuntu asks for your password twice to make sure you did
not make a mistake while typing). Once you have restored your password,
return to the normal system environment by entering:
# init 2
Login as usual and continue enjoying Ubuntu.
I accidentally deleted some files that I need
If you’ve deleted a file by accident, you may be able to recover it from
Ubuntu’s Trash folder. is is a special folder where Ubuntu stores deleted
files before they are permanently removed from your computer.
To access the Trash folder click on the trash icon at the boom of the
Unity Launcher.
If you want to restore deleted items from the Trash:
. Open Trash
. Click on each item you want to restore to select it. Press and hold Ctrl
to select multiple items.
. Click Restore Selected Items to move the deleted items back to their
original locations.
How do I clean Ubuntu?
Ubuntu’s soware packaging system accumulates unused packages and
temporary files through regular updates and use. ese temporary files, also
called caches, contain files from all of the installed packages. Over time, this
cache can grow quite large. Cleaning out the cache allows you to reclaim
space on your computer’s hard drive for storing your documents, music,
photographs, or other files.
To clear the cache, you can either use the clean, or the autoclean option
for the command-line program apt-get.
To run clean, open Terminal and enter: The clean command will remove every
single cached item, while the autoclean
command only removes cached items that can
no longer be downloaded (these items are
often unnecessary).
$ sudo apt-get clean
Packages can also become unused over time. If a package was installed
to assist with running another program—and that program was subse-

     .
quently removed—you no longer need the supporting package. You can
remove it with apt-get autoremove.
Load Terminal and enter:
$ sudo apt-get autoremove
I can’t play certain audio or video files
Many of the formats used to deliver rich media content are proprietary,
meaning they are not free to use, modify, or distribute with an open-source
operating system like Ubuntu. erefore, Ubuntu does not include the ca-
pability to use these formats by default; however, users can easily configure
Ubuntu to use these proprietary formats. For more information about the
differences between open source and proprietary soware, see Chapter :
Learning More.
If you find yourself in need of a proprietary format, you can install the
required files from the Ubuntu Soware Center. Ensure that you have the
Universe and Multiverse repositories enabled before continuing. See the
Soware Sources section to learn how to enable these repositories. When
you are ready to continue, install the necessary soware as follows:
. Open the Ubuntu Soware Center by searching for it from the Dash (the
top-most buon on the Launcher).
. Search for ubuntu-restricted-extras by typing “Ubuntu restricted
extras” in the search box on the right-hand side of the Ubuntu Soware
Center main window. When the Soware Center finds the appropriate
soware, click the arrow next to its title.
. Click Install, then wait while Ubuntu installs the soware.
One program that can play many of these formats is  media player.
It can be installed from the Ubuntu Soware Center. Once Ubuntu has
successfully installed this soware, your rich media content should work
properly.
How can I change my screen resolution?
e image on every monitor is composed of millions of lile colored dots
called pixels. Changing the number of pixels displayed on your monitor is
called “changing the resolution.” Increasing the resolution will make the
displayed images sharper, but will also tend to make them smaller. e
opposite is true when screen resolution is decreased. Most monitors have
a “native resolution,” which is a resolution that most closely matches the
number of pixels in the monitor. Your display will usually be sharpest when
your operating system uses a resolution that matches your display’s native
resolution.
e Ubuntu configuration utility Displays allows users to change the
resolution. Open it by clicking on the session indicator and then on Dis-
plays…. e resolution can be changed using the drop-down list within
the program. Picking options higher up on the list (for example, those with
larger numbers) will increase the resolution.
You can experiment with various resolutions by clicking Apply at the
boom of the window until you find one that is comfortable. Typically,
the highest resolution will be the native resolution. Selecting a resolution
and clicking Apply will temporarily change the screen resolution to the
selected value, and a dialog box will also be displayed for  seconds. is
dialog box allows you to revert to the previous resolution seing or keep

the new resolution seing. If you’ve not accepted the new resolution and/or
 seconds have passed, the dialog box will disappear and the display’s
resolution will return to its previous seing.
Figure 7.3: You can revert back to your old
settings if you need to.
is feature was implemented to prevent someone from being locked out
of the computer by a resolution that distorts the monitor output and makes
it unusable. When you have finished seing the screen resolution, click
Close.
Ubuntu is not working properly on my Apple MacBook or MacBook Pro
When installed on notebook computers from Apple—such as the MacBook
or MacBook Pro—Ubuntu does not always enable all of the computer’s
built-in components, including the iSight camera and the Airport wireless
Internet adapter. Luckily, the Ubuntu community offers documentation
on fixing these and other problems. If you are having trouble installing or
using Ubuntu on your Apple notebook computer, please follow the instruc-
tions at https://help.ubuntu.com/community/MacBook. You can select the
appropriate guide aer identifying your computer’s model number.
Ubuntu is not working properly on my Asus EeePC
When installed on netbook computers from Asus—such as the EeePC—
Ubuntu does not always enable all of the computer’s built-in components,
including the keyboard shortcut keys and the wireless Internet adapter.
e Ubuntu community offers documentation on enabling these com-
ponents and fixing other problems. If you are having trouble installing
or using Ubuntu on your Asus EeePC, please follow the instructions at
https://help.ubuntu.com/community/EeePC. is documentation page con-
tains information pertaining specifically to EeePC netbooks.
To enable many of the features and Function Keys, a quick fix is to add
“acpi_osi=Linux” to your grub configuration. From the Terminal
$ gksudo gedit /etc/default/grub

     .
and very carefully change the line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"
Save and close the file. en, from the terminal:
$ sudo update-grub
Aer the command finishes, and you restart the computer, you will be able
to use the Fn keys normally.
My hardware is not working properly
Ubuntu occasionally has difficulty running on certain computers, usually
when hardware manufacturers use non-standard or proprietary compo-
nents. e Ubuntu community offers documentation to help you trou-
bleshoot many common issues in this situation, including problems with
wireless cards, scanners, mice, and printers. You can find the complete
hardware troubleshooting guide on Ubuntu’s support wiki, accessible at
https://wiki.ubuntu.com/HardwareSupport. If your hardware problems
persist, please see Geing more help for more troubleshooting options or
information on obtaining support or assistance from an Ubuntu user.
Getting more help
is guide does not cover every possible workflow, task, issue, or problem
in Ubuntu. If you require assistance beyond the information in the manual,
you can find a variety of support opportunities online.
More details about many support options available to you can be found
at Finding additional help and support later in this book.

8 Learning More
What else can I do with Ubuntu?
At this point, you should now be able to use Ubuntu for most daily activ-
ities—such as browsing the web, sending email, and creating documents.
Now, you may be interested in learning about other versions of Ubuntu
that may integrate into your digital lifestyle. In this chapter, we’ll introduce
additional versions of Ubuntu designed and specialized for certain tasks.
We’ll also provide resources for answering any remaining questions as well
as direct you to how you can get involved in the worldwide community
of Ubuntu users. First, we’ll discuss the technologies that make Ubuntu a
powerful collection of soware and a progressive operating system.
Open source software
Ubuntu is open source soware (OSS). OSS differs from proprietary so-
ware. Proprietary soware is defined as soware whose source code is
not freely available for modification or distribution by anyone but the
rightsholder. Microso Windows and Adobe Photoshop are examples of
proprietary soware.
Unlike proprietary soware applications, the soware included with
Ubuntu is specifically licensed to promote sharing and collaboration. e
legal rules governing Ubuntu’s production and distribution ensure that
anyone can obtain, run, or share it for any purpose. Users can modify open
source soware to suit their individual needs, to share it, to improve it, or to
translate it into other languages—provided they release the source code for
these modifications so others can do the same. In fact, the terms of many
open source licensing agreements actually make it illegal not to do so. is
understanding helps explain why Ubuntu is called open source soware.
For more information regarding Ubuntu’s soware licensing standards, see
http://www.ubuntu.com/project/about-ubuntu/licensing.
Because OSS is developed by large communities of programmers located
throughout the world, it benefits from both rapid development cycles and
speedy security releases when bugs are identified in the soware. In other
words, OSS is updated, enhanced, and made more secure every day as
programmers all over the world continue to improve it.
In addition to these technical advantages, OSS also has economic bene-
fits. While users must adhere to the terms of an OSS licensing agreement
when installing and using Ubuntu, they needn’t pay to obtain this license.
While not all OSS is free of monetary costs, a vast majority of OSS is avail-
able for free.
To learn more about open source soware, see the Open Source Initia-
tive’s open source definition, available at http://www.opensource.org/docs/
definition.php.
Distribution families
Ubuntu is one of several popular operating systems based on Linux. ese
Linux-based operating systems—called Linux “distributions”—may look

     .
different from Ubuntu at first glance, but they share similar characteristics
because of their common roots.
Linux distributions can be divided into two broad families: the Debian
family and the Red Hat family. Each family is named for a distribution on
which subsequent distributions are based. For example, “Debian” refers to
both the name of a Linux distribution as well as the family of distributions
derived from Debian. Ubuntu is part of this family. When describing rela-
tionships between various open source projects, soware developers oen
use the metaphor of tributaries connecting to a common body of water.
For this reason, you may hear someone say that Ubuntu is located “down-
stream” from Debian, because alterations to the Debian family ”flow” into
new versions of Ubuntu. Additionally, improvements to Ubuntu usually
trickle “upstream”—back to Debian and its family members as the Debian
family benefits from the work of the Ubuntu community. Other distribu-
tions in the Debian family include Linux Mint, Xandros, and CrunchBang
Linux. Distributions in the Red Hat family include Fedora and Mandriva.
e most significant difference between Debian-based and Red Hat-
based distributions is the system each uses for installing and updating
soware. ese systems are called Package management systems. Package
management systems are the means by which users can install, remove,
and organize soware installed on computers with open source operating
systems like Ubuntu. Debian soware packages are  files, while Red Hat
soware packages are  files. e two systems are generally incompati-
ble. For more information about package management, review the chapter
on Chapter : Soware Management.
You will also find specialized Linux distributions for certain tasks. Next,
we’ll describe these versions of Ubuntu and explain the uses for which each
has been developed.
Choosing amongst Ubuntu and its derivatives
Just as Ubuntu is based on Debian, several distributions are subsequently
based on Ubuntu. Each differs with respect to the soware included as part
of the distribution. Some are developed for general use, while others are
designed for accomplishing a more narrow set of tasks.
Alternative interfaces
Ubuntu . features a new graphical user interface () based on the
open source  desktop. Previous versions of Ubuntu use the 
desktop. As we explained in Chapter : e Ubuntu Desktop, a “user inter-
face” is a collection of soware elements—icons, colors, windows, themes,
and menus—that determine how someone may interact with a computer.
Some people prefer using alternatives to , so they have created
Ubuntu distributions featuring different user interfaces. ese include:
‣ Kubuntu, which uses the  graphical environment
‣ Lubuntu, which uses the  graphical environment
‣ Xubuntu, which uses the  graphical environment
Additionally, each of these distributions may contain default applications
different from those featured in Ubuntu. For instance, the default music
player in Ubuntu is Rhythmbox. In Lubuntu, the default music player is
Aqualung, and in Kubuntu, the default is Amarok. Be sure to investigate

  
these differences if you are considering installing an Ubuntu distribution
with an alternative desktop environment.
For more information about these and other derivative distributions, see
http://www.ubuntu.com/project/derivatives.
Task-specific distributions
Other Ubuntu distributions have been created to accomplish specific tasks
or run in specialized environments and seings.
Ubuntu Server Edition
e Ubuntu Server Edition is an operating system optimized to perform
multi-user tasks. Such tasks may include file sharing, website, or email
hosting. If you are planning to use a computer to perform these types of
tasks, you may wish to use this specialized server distribution in conjunc-
tion with server hardware. While it is possible to run a server-type envi-
ronment using only the desktop version of Ubuntu, it is not advised as the
Server Edition is beer optimized for the multi-user environment.
is manual does not explain the process of running a secure web server
or performing other tasks with Ubuntu Server Edition. For details on using
Ubuntu Server Edition, refer to the manual at http://www.ubuntu.com/
business/server/overview.
Edubuntu
Edubuntu is an Ubuntu derivative customized for use in schools and other
educational institutions. Edubuntu contains soware similar to that offered
in Ubuntu but also features additional applications like a collaborative text
editor and educational games.
For additional information regarding Edubuntu, visit http://www.
edubuntu.org/
Ubuntu Studio
e derivative of Ubuntu called Ubuntu Studio is designed specifically for
people who use computers to create and edit multimedia projects. Ubuntu
Studio features applications to help users manipulate images, compose
music, and edit video. While users can install these applications on comput-
ers running the desktop version of Ubuntu, Ubuntu Studio makes them all
available immediately upon installation.
If you would like to learn more about Ubuntu Studio (or obtain a copy
for yoursel), visit http://ubuntustudio.org/.
Mythbuntu
Mythbuntu allows users to turn their computers into entertainment sys-
tems. Mythbuntu helps users organize and view various types of multime-
dia content such as movies, television shows, and video podcasts. Users
with  tuners in their computers can also use Mythbuntu to record live
video and television shows.

Finding additional help and support
is guide cannot possibly contain everything you’ll ever need to know
about Ubuntu. We encourage you to take advantage of Ubuntu’s vast com-
munity when seeking further information, troubleshooting technical issues,
or asking questions about your computer.
It’s important to note that the Internet is full of third-party resources
as well as individuals who post information on blogs and forums. While
these resources can oen seem like great resources, some could be mis-
leading or outdated. It’s always best to verify information from third-party
sources before taking their advice. When possible, rely on official Ubuntu
documentation for assistance with Ubuntu.
Now, let’s discuss a few of the available resources to learn more about
Ubuntu and other Linux distributions.
Live chat
If you are familiar with Internet Relay Chat (), you can use chat clients
such as XChat or Pidgin to join the channel #ubuntu on irc.freenode.net. In
this channel, hundreds of volunteer users can answer your questions or of-
fer technical support in real time. To learn more about using Internet Relay
Chat to seek help with Ubuntu, visit https://help.ubuntu.com/community/
InternetRelayChat.
LoCo teams
e Ubuntu community contains dozens of local user groups called “LoCo
teams.” Distributed throughout the world, these teams offer support and
advice, answer questions, and promote Ubuntu in their communities by
hosting regular events. To locate or contact the LoCo team nearest you,
visit http://loco.ubuntu.com/.
Books and Magazines
Many books have been wrien about Ubuntu, and professional magazines
oen feature news and information related to Ubuntu. You will frequently
find these resources at your local bookstore or newsstand. Additionally,
many of these print publications are also available as digital downloads for
purchase in the Ubuntu Soware Center. To find these resources, launch the
Soware Center, then click on “Books & Magazines” in the le panel.
Official Ubuntu Documentation
e Ubuntu Documentation Team maintains a series of official wiki pages
designed to assist both new and experienced users wishing to learn more
about Ubuntu. e Ubuntu community endorses these documents, which
serve as a reliable first point of reference for users seeking online help. You
can access these resources at http://help.ubuntu.com. To get to the built-in
Ubuntu Desktop Guide, type help in the Dash.
The Ubuntu Forums
e Ubuntu Forums are the official forums of the Ubuntu community. Mil-
lions of Ubuntu users use them daily to seek help and support from one
another. You can create an Ubuntu Forums account in minutes. To create

  
an account and learn more about Ubuntu from community members, visit
http://ubuntuforums.org.
Launchpad Answers
Launchpad, an open source code repository and user community, provides a
question and answer service that allows anyone to ask questions about any
Ubuntu-related topic. Signing up for a Launchpad account takes just a few
seconds. You can ask a question by visiting Launchpad at https://answers.
launchpad.net/ubuntu.
Ask Ubuntu
Ask Ubuntu is a free, community-driven website for Ubuntu users and
developers. Like the Ubuntu Forums, it allows users to post questions for
other members of the Ubuntu community to answer. But Ask Ubuntu also
allows visitors to “vote” on the answers users provide, so the most useful or
helpful responses get featured more prominently on the site. Ask Ubuntu is
part of the Stack Exchange network of websites and is one of the best free
Ubuntu support resources available. Visit http://www.askubuntu.com to get
started.
Search Engines
Because Ubuntu is a popular open source operating system, many users
have wrien about it online. erefore, using search engines to locate
answers to your questions about Ubuntu is oen an effective means of
acquiring help. When using search engines to answer questions about
Ubuntu, ensure that your search queries are as specific as possible. In other
words, a search for “Unity interface” will return results that are less useful
than those associated with the query “how to use Ubuntu Unity interface”
or “how to customize Ubuntu Unity interface.”
Community support
If you’ve exhausted all these resources and still can’t find answers to your
questions, visit Community Support at http://www.ubuntu.com/support/

The Ubuntu community
Ubuntu is the flagship product created by a global community of passionate
users who want to help others adopt, use, understand, and even modify or
enhance Ubuntu. By choosing to install and run Ubuntu, you’ve become
part of this community. As you learn more about Ubuntu, you may wish
to collaborate with others as you promote Ubuntu to new users, to share
Ubuntu advice, or to answer other users’ questions. In this section, we’ll
discuss a few community projects that can connect you to other Ubuntu
users.

erary or artistic work, or phonogram or performance and includes
cinematographic adaptations or any other form in which the Work
may be recast, transformed, or adapted including in any form recog-
nizably derived from the original, except that a work that constitutes
a Collection will not be considered an Adaptation for the purpose of
this License. For the avoidance of doubt, where the Work is a musical
work, performance or phonogram, the synchronization of the Work in
timed-relation with a moving image (“synching”) will be considered
an Adaptation for the purpose of this License.

as encyclopedias and anthologies, or performances, phonograms
or broadcasts, or other works or subject maer other than works
listed in Section () below, which, by reason of the selection and
arrangement of their contents, constitute intellectual creations, in
which the Work is included in its entirety in unmodified form along
with one or more other contributions, each constituting separate and
independent works in themselves, which together are assembled into
a collective whole. A work that constitutes a Collection will not be
considered an Adaptation (as defined below) for the purposes of this
License.
(c) “Creative Commons Compatible License” means a license that is
listed at http://creativecommons.org/compatiblelicenses that has been
approved by Creative Commons as being essentially equivalent to this
License, including, at a minimum, because that license: (i) contains
terms that have the same purpose, meaning and effect as the License
Elements of this License; and, (ii) explicitly permits the relicensing
of adaptations of works made available under that license under this
License or a Creative Commons jurisdiction license with the same
License Elements as this License.
(d) “Distribute” means to make available to the public the original and
copies of the Work or Adaptation, as appropriate, through sale or
other transfer of ownership.

. Fair Dealing Rights. Nothing in this License is intended to reduce, limit,
or restrict any uses free from copyright or rights arising from limitations
or exceptions that are provided for in connection with the copyright
protection under copyright law or other applicable laws.
. License Grant. Subject to the terms and conditions of this License, Licen-
sor hereby grants You a worldwide, royalty-free, non-exclusive, perpet-
ual (for the duration of the applicable copyright) license to exercise the
rights in the Work as stated below:
(a) to Reproduce the Work, to incorporate the Work into one or more
Collections, and to Reproduce the Work as incorporated in the Collec-
tions;
(b) to create and Reproduce Adaptations provided that any such Adap-
tation, including any translation in any medium, takes reasonable
steps to clearly label, demarcate or otherwise identify that changes
were made to the original Work. For example, a translation could be
marked “e original work was translated from English to Spanish,”
or a modification could indicate “e original work has been modi-
fied.”;
(c) to Distribute and Publicly Perform the Work including as incorpo-
rated in Collections; and,
(d) to Distribute and Publicly Perform Adaptations.
(e) For the avoidance of doubt:
i. Non-waivable Compulsory License Schemes. In those jurisdictions
in which the right to collect royalties through any statutory or
compulsory licensing scheme cannot be waived, the Licensor re-
serves the exclusive right to collect such royalties for any exercise
by You of the rights granted under this License;
ii. Waivable Compulsory License Schemes. In those jurisdictions
in which the right to collect royalties through any statutory or
compulsory licensing scheme can be waived, the Licensor waives
the exclusive right to collect such royalties for any exercise by You
of the rights granted under this License; and,
iii. Voluntary License Schemes. e Licensor waives the right to col-
lect royalties, whether individually or, in the event that the Licen-
sor is a member of a collecting society that administers voluntary
licensing schemes, via that society, from any exercise by You of the
rights granted under this License.
e above rights may be exercised in all media and formats whether
now known or hereaer devised. e above rights include the right to
make such modifications as are technically necessary to exercise the
rights in other media and formats. Subject to Section (), all rights
not expressly granted by Licensor are hereby reserved.
. Restrictions. e license granted in Section  above is expressly made
subject to and limited by the following restrictions:
(a) You may Distribute or Publicly Perform the Work only under the
terms of this License. You must include a copy of, or the Uniform
Resource Identifier (URI) for, this License with every copy of the Work
You Distribute or Publicly Perform. You may not offer or impose
any terms on the Work that restrict the terms of this License or the
ability of the recipient of the Work to exercise the rights granted to
that recipient under the terms of the License. You may not sublicense
the Work. You must keep intact all notices that refer to this License
and to the disclaimer of warranties with every copy of the Work

     .
You Distribute or Publicly Perform. When You Distribute or Publicly
Perform the Work, You may not impose any effective technological
measures on the Work that restrict the ability of a recipient of the
Work from You to exercise the rights granted to that recipient under
the terms of the License. is Section (a) applies to the Work as
incorporated in a Collection, but this does not require the Collection
apart from the Work itself to be made subject to the terms of this
License. If You create a Collection, upon notice from any Licensor You
must, to the extent practicable, remove from the Collection any credit
as required by Section (c), as requested. If You create an Adaptation,
upon notice from any Licensor You must, to the extent practicable,
remove from the Adaptation any credit as required by Section (c), as
requested.
(b) You may Distribute or Publicly Perform an Adaptation only under the
terms of: (i) this License; (ii) a later version of this License with the
same License Elements as this License; (iii) a Creative Commons juris-
diction license (either this or a later license version) that contains the
same License Elements as this License (e.g., Aribution-ShareAlike
. US)); (iv) a Creative Commons Compatible License. If you license
the Adaptation under one of the licenses mentioned in (iv), you must
comply with the terms of that license. If you license the Adaptation
under the terms of any of the licenses mentioned in (i), (ii) or (iii) (the
“Applicable License”), you must comply with the terms of the Ap-
plicable License generally and the following provisions: (I) You must
include a copy of, or the URI for, the Applicable License with every
copy of each Adaptation You Distribute or Publicly Perform; (II) You
may not offer or impose any terms on the Adaptation that restrict
the terms of the Applicable License or the ability of the recipient of
the Adaptation to exercise the rights granted to that recipient un-
der the terms of the Applicable License; (III) You must keep intact all
notices that refer to the Applicable License and to the disclaimer of
warranties with every copy of the Work as included in the Adapta-
tion You Distribute or Publicly Perform; (IV) when You Distribute or
Publicly Perform the Adaptation, You may not impose any effective
technological measures on the Adaptation that restrict the ability of a
recipient of the Adaptation from You to exercise the rights granted to
that recipient under the terms of the Applicable License. is Section
(b) applies to the Adaptation as incorporated in a Collection, but this
does not require the Collection apart from the Adaptation itself to be
made subject to the terms of the Applicable License.
(c) If You Distribute, or Publicly Perform the Work or any Adaptations
or Collections, You must, unless a request has been made pursuant
to Section (a), keep intact all copyright notices for the Work and
provide, reasonable to the medium or means You are utilizing: (i) the
name of the Original Author (or pseudonym, if applicable) if supplied,
and/or if the Original Author and/or Licensor designate another party
or parties (e.g., a sponsor institute, publishing entity, journal) for ari-
bution (“Aribution Parties”) in Licensor’s copyright notice, terms of
service or by other reasonable means, the name of such party or par-
ties; (ii) the title of the Work if supplied; (iii) to the extent reasonably
practicable, the URI, if any, that Licensor specifies to be associated
with the Work, unless such URI does not refer to the copyright no-
tice or licensing information for the Work; and (iv) , consistent with
Ssection (b), in the case of an Adaptation, a credit identifying the

 
use of the Work in the Adaptation (e.g., “French translation of the
Work by Original Author,” or “Screenplay based on original Work
by Original Author”). e credit required by this Section (c) may be
implemented in any reasonable manner; provided, however, that in
the case of a Adaptation or Collection, at a minimum such credit will
appear, if a credit for all contributing authors of the Adaptation or
Collection appears, then as part of these credits and in a manner at
least as prominent as the credits for the other contributing authors.
For the avoidance of doubt, You may only use the credit required by
this Section for the purpose of aribution in the manner set out above
and, by exercising Your rights under this License, You may not im-
plicitly or explicitly assert or imply any connection with, sponsorship
or endorsement by the Original Author, Licensor and/or Aribution
Parties, as appropriate, of You or Your use of the Work, without the
separate, express prior wrien permission of the Original Author,
Licensor and/or Aribution Parties.
(d) Except as otherwise agreed in writing by the Licensor or as may be
otherwise permied by applicable law, if You Reproduce, Distribute
or Publicly Perform the Work either by itself or as part of any Adap-
tations or Collections, You must not distort, mutilate, modify or take
other derogatory action in relation to the Work which would be prej-
udicial to the Original Author’s honor or reputation. Licensor agrees
that in those jurisdictions (e.g. Japan), in which any exercise of the
right granted in Section (b) of this License (the right to make Adap-
tations) would be deemed to be a distortion, mutilation, modiﬁcation
or other derogatory action prejudicial to the Original Author’s honor
and reputation, the Licensor will waive or not assert, as appropriate,
this Section, to the fullest extent permied by the applicable national
law, to enable You to reasonably exercise Your right under Section
(b) of this License (right to make Adaptations) but not otherwise.

. Termination
(a) is License and the rights granted hereunder will terminate automat-

of this License.
(b) Subject to the above terms and conditions, the license granted here is
perpetual (for the duration of the applicable copyright in the Work).
Notwithstanding the above, Licensor reserves the right to release
the Work under different license terms or to stop distributing the
Work at any time; provided, however that any such election will not
serve to withdraw this License (or any other license that has been, or
is required to be, granted under the terms of this License), and this
License will continue in full force and effect unless terminated as
stated above.
. Miscellaneous
(a) Each time You Distribute or Publicly Perform the Work or a Collec-
tion, the Licensor offers to the recipient a license to the Work on the
same terms and conditions as the license granted to You under this
License.
(b) Each time You Distribute or Publicly Perform an Adaptation, Licensor
offers to the recipient a license to the original Work on the same
terms and conditions as the license granted to You under this License.
(c) If any provision of this License is invalid or unenforceable under
applicable law, it shall not affect the validity or enforceability of the
remainder of the terms of this License, and without further action
by the parties to this agreement, such provision shall be reformed
to the minimum extent necessary to make such provision valid and
enforceable.
(d) No term or provision of this License shall be deemed waived and no
breach consented to unless such waiver or consent shall be in writing
and signed by the party to be charged with such waiver or consent.
(e) is License constitutes the entire agreement between the parties
with respect to the Work licensed here. ere are no understandings,
agreements or representations with respect to the Work not specified
here. Licensor shall not be bound by any additional provisions that
may appear in any communication from You. is License may not be
modified without the mutual wrien agreement of the Licensor and
You.
() e rights granted under, and the subject maer referenced, in this
License were draed utilizing the terminology of the Berne Conven-
tion for the Protection of Literary and Artistic Works (as amended on
September , ), the Rome Convention of , the WIPO Copy-
right Treaty of , the WIPO Performances and Phonograms Treaty
of  and the Universal Copyright Convention (as revised on July
, ). ese rights and subject maer take effect in the relevant
jurisdiction in which the License terms are sought to be enforced
according to the corresponding provisions of the implementation of
those treaty provisions in the applicable national law. If the standard
suite of rights granted under applicable copyright law includes addi-
tional rights not granted under this License, such additional rights are
deemed to be included in the License; this License is not intended to
restrict the license of any rights under applicable law.
