\marginnote{Your graphics card is the component in your computer which outputs to the display. Whether you are watching videos on YouTube, viewing \acronym{DVD}s, or simply enjoying the smooth transition effects when you maximize/minimize your windows, your graphics device is doing the hard work behind the scenes.} The majority of graphics cards are manufactured by three well-known companies: Intel, \acronym{AMD}/\acronym{ATI}, and \acronym{NVIDIA} 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 \userinput{lspci} in a terminal. The \application{Ubuntu Software Center} houses a number 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 manufactured by the above companies, and many others, out of the box. That means you don't have to find and install any drivers yourself, Ubuntu takes care of it all.

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 \menu{System Settings}, then open \menu{Software 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 \button{Activate} to enable the driver. This 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.

In the left hand pane of the \window{New Printer} window any printers that you can install will be listed. Select the printer that you would like to install and click \button{Forward}.

A volume icon is present on the top panel which provides quick access to a number of audio related functions. When you click on the volume icon you are greeted with four options: A mute option at the very top, a slider button which you can move horizontally to increase/decrease volume, a shortcut to the default music player, Rhythmbox, and an option for accessing the Sound Settings. Selecting \emph{Sound Settings} opens up another window, which provides access to options for changing input and output hardware preferences for speakers, microphones and headphones. It also provides options for setting the volume level for each application. Sound Settings can also be found from \menu{System Settings}. It is known as \emph{Sound}.

The icon can control various aspects of the system, application volume and music players like Rhythmbox, Banshee, Clementine and Spotify. The volume indicator icon can now be easily referred to as the sound menu, given the diverse functionality of the icon. \marginnote{You can start and control the default music player, \application{Rhythmbox}, by simply left clicking on the sound menu and selecting \application{Rhythmbox} from the list. Clicking the \button{play} button also starts the player.} Media controls available include play/pause, previous track, and next track. You can also switch between different playlists from the \emph{Choose Playlist} option. If the current playing song has album art, it will show up beside the name of the current track, otherwise you will see only the details of the song. It displays the track name, the artist name and the album name of the current track.

You can save the scanned documents and pictures in \acronym{JPEG}. You can also save in \acronym{PDF} format to enable opening in \application{Acrobat Reader}. To do that, add the extension \code{.pdf} at the end of the filename.

\gls{USB} ports are available as standard on almost all computers available now. They are used to connect a multitude of devices to your computer. These could include portable hard drives, flash drives, removable \acronym{CD}/\acronym{DVD}/Blu-ray drives, printers, scanners and mobile phones.

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 \acronym{GPS} 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.

First, insert your Ubuntu \acronym{DVD} into your computer and then restart the computer, making sure to instruct your computer to boot from the \acronym{DVD} drive and not the hard drive (see \chaplink{ch:installation}). Next, choose your language (\eg, English) and select \menu{Try Ubuntu}. Once Ubuntu starts, click on the top-most icon in the Launcher (the Dash icon). Then, search for \userinput{Terminal} using the search box. Then, select Terminal in the search results (or press \keystroke{Ctrl+Alt+T}). A window should open with a blinking prompt line. Enter the following, and press the \keystroke{Enter} key:

Partition table entries are not in disk order

Finally, remove the Ubuntu disc from your \acronym{DVD-ROM} drive, reboot your computer, and then start enjoying your Ubuntu operating system once again.

The Ubuntu configuration utility \application{Displays} allows users to change the resolution. Open it by clicking on the \menu{session indicator} and then on \menu{Displays\ldots}. The 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.
