Many people have contributed their time freely to this project. If you notice any errors or think we have left something out, feel free to contact us. We do everything we can to make sure that this manual is up to date, informative, and professional. Our contact details are as follows:

\marginnote{To access the \window{Connection Information} window, you will need to make sure that networking is enabled. Otherwise this option will be gray and you will not be able to select it through the right-click menu of the NetworkManager applet. To enable networking, right-click on the NetworkManager applet and select \button{Enable Networking} from the popup menu.}

You can also change the fonts used throughout your desktop through the Appearance Preferences window by clicking on the \button{Fonts} tab. You can individually set the font style and size for applications, documents, desktop items, window titles, and for anything using fixed width fonts. The Rendering section at the bottom of the Fonts window gives you four options for changing the way that fonts are drawn on your screen. Changing these may improve the appearance of text on different types of monitors.

To start Rescue mode, shut down your computer, then power it up. As the computer starts up, press \textbf{Esc} when you see the white-on-black screen with a countdown (the \acronym{GRUB} prompt). Select the \textbf{Rescue mode} option using the arrow keys on your keyboard. Rescue mode should be the second item in the list. \screenshot{08-grub-boot-screen.png}{ss:grub-boot-screen}{This is the grub screen in which you can choose the rescue mode.}

\marginnote{Canonical is the company that provides financial and technical support for Ubuntu. They have employees based around the world who work on developing and improving the operating system, as well as reviewing work submitted by volunteer contributors. To learn more about Canonical, go to \url{http://www.canonical.com}.}

The open a message in its own window, double click a message in the message list. The message should then open in a separate window. You can go back to the message list and open another message, if needed.

If a message was sent with \acronym{HTML} formatting, some of the images may not be displayed when a message is previewed. To display the missing images, open the \menu{View} menu from the menubar, then \menu{Load Images}, or press \keystroke{Ctrl+I}. If your Internet connection is active, the missing images should then load.

Enter your password at the prompt, as above. Allow Ubuntu to process the command, then enter:

Enter your username, press \textbf{Enter}, and then enter your password. (Characters \textit{will not} appear on the screen as you enter your password. Don't worry\dash this behavior is normal and was implemented for security purposes.) Next, enter the following code and press enter:

Finally, if you do not have a working internet connection, Ubuntu can install some software packages straight from your installation \acronym{CD}. To do this, insert the disc into your computer's \acronym{CD} drive, then select the check box next to \button{Installable from the \acronym{CD-ROM}/\acronym{DVD}}. Once this check box is ticked, the disc will be treated just like an online repository, and applications will be installable straight from the \acronym{CD} through the \application{Software Center}.

To add a group, click \button{Add}. In the dialog that appears, enter the group name and select the names of users you'd like to add to the group.

Replace ``username'' above with your username. Ubuntu will prompt you for a new password. Enter your desired password, press enter and then type your password again, pressing enter after you are 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:

\emph{Type your password into the authentication window that appears.} Removing software also requires that you enter your password to help protect your computer against unauthorized changes. The package will then be queued for removal, and will appear under the \tab{In Progress} section in the sidebar.

Then, in the \textfield{Alias} text field, enter the contact's name as you would like to see it in your contact list. Click \button{Add} to add the contact to your list of contacts.

You can also add your network printer by entering the \acronym{IP} address of the printer. Select \textbf{Find Network Printer}, type in the \acronym{IP} address of the printer in the box that reads \textbf{Host:} and press the \button{Find} button. Ubuntu will find the printer and add it. Most recent printers are detected by Ubuntu automatically. If Ubuntu cannot detect the printer automatically, it will ask you to enter the make and model number of the printer.

On the next screen, \window{Account Management}, enter a descriptive name for this account. If you plan to use more than one email provider with \application{Evolution}, you will use this name to distinguish between the different accounts.

In the \window{Enter Password} window, enter your password and click \window{OK}. If you wish for \application{Evolution} to remember this password and not ask you in the future, you can select the \checkbox{Remember this password} option.

If your email provider recommends an \acronym{POP} connection, choose \menu{POP} from the \dropdown{Server Type} drop-down list. In the \textfield{Server} field, enter the Internet name of your mail server. For example, \textbf{pop.example.com}. In the \textfield{Username} field, enter the username that you use to log into your email system, for example \textbf{joe.x.user}, or \textbf{joe.x.user@example.com}.

If your email provider recommends an \acronym{IMAP} connection, choose \menu{IMAP} from the \dropdown{Server Type} drop-down list. In the \textfield{Server} field, enter the Internet name of your mail server. For example, \textbf{imap.example.com}. In the \textfield{Username} field, enter the username that you use to log into your email system, for example \textbf{joe.x.user}.

When the calender is expanded there is a button labeled \button{Locations}, which will open a small world map when clicked. Here you can further set up your location preferences by clicking \button{Edit}. In the window that appears, click \button{Add}, then enter your location in the text field. If you live in a major city it may be on the list already; if not, you can enter your latitude and longitude manually (try searching online if you don't have this information). Make sure your time zone is selected, then click \button{OK} to return to the preferences screen.

To try out Ubuntu using the Live \acronym{CD}, insert the Ubuntu \acronym{CD} into your \acronym{CD} drive and restart your computer. Most computers are able to detect when a ``bootable'' \acronym{CD} is present in your drive at startup\dash that is, a \acronym{CD} that will temporarily take precedence over your usual operating system. As your computer starts, it will run whatever information is stored on this bootable \acronym{CD}, rather than the information stored on your hard drive which your computer usually looks for.

At the very bottom of the \menu{Applications} menu is the \application{Ubuntu Software Center}. This application gives you access to a library of software that you can download. The main screen in the \application{Ubuntu Software Center} is similar to your \menu{Applications} menu, for easy searching. If you know the name of the program you're looking for, just enter it in the search text field on the top right of the \application{Ubuntu Software Center} window. The \application{Ubuntu Software Center} keeps track of programs that are installed on your computer. If you're simply curious as to what is available, you can explore the software available using the categories listed on the left side of the window.

In the \textfield{Network name} field, enter the name of the wireless network. This name is also known as an \emph{\acronym{SSID}}. Please enter the network name exactly as it was given to you.

\marginnote{A \acronym{VPN} is a ``Virtual Private Network,'' and is sometimes used to help secure connections. \acronym{DSL}s are ``Digital Subscriber Lines,'' a type of a broadband connection.}

\textbf{Templates} stores email message templates\dash partial messages that you have composed and saved as templates. You can use a message stored in the template folder as a starting point for other messages.

\marginnote{Many people installing Ubuntu for the first time are currently using either Windows \acronym{XP}, Windows Vista, Windows 7, or Mac \acronym{OS~X} on their computer. Ubuntu provides you with the option of either \emph{replacing} your existing operating system altogether, or installing Ubuntu alongside your existing system. The latter is called \emph{dual-booting}. Whenever you turn on or restart your computer, you will be given the option to select which operating system you want to use for that session.} Use this option if you want to erase your entire disk. This will delete any existing operating systems that are installed on that disk, such as Windows \acronym{XP}, and install Ubuntu in its place. This option is also useful if you have an empty hard drive, as Ubuntu will automatically create the necessary partitions for you.

\textbf{Junk} stores messages that have been identified as being junk. Junk mail is also known as ``spam.''

\textbf{Outbox} contains messages that you've finished composing, but which have not been sent yet. For example, if you are working on your email while offline (such as in an airplane), you can still click the \button{Send} button on an email message that you finish writing. The message will be moved to the Outbox, and will remain there until the next time you are able to send and receive messages. Once you can send and receive messages, all email messages in the Outbox will be sent out.

The folder list is the way that \application{Evolution} separates and categorizes your email. The first group of folders in the list is titled ``On This Computer.'' This set of folders are your \emph{local} folders\dash they reside on your computer only. If you use \acronym{POP} servers to retrieve your email, any new message will be placed in the \textbf{Inbox} local folder.

The \application{Evolution} window is divided into four parts. At the top are the menubar and toolbar. The menubar lets you access most of the functionality of \application{Evolution}, while the toolbar provides some convenient shortcuts to some of the most frequently used features.

On the right side of the window are the message list, and the message preview beneath it. The message list shows all of the messages in the currently selected folder, or matching your search request. The message preview shows the contents of your currently selected message in the list above the preview.

You can also change your account settings by clicking \dropdown{Broadcast Accounts\ldots}, this opens the \window{Social accounts} window.

On the next screen, \window{Account Management}, enter a descriptive name for this account. If you plan to use more than one email provider with \application{Evolution}, you will use this name to distinguish between the different accounts.

Finalizing account options

The folder list is the way that \application{Evolution} separates and categorizes your email. The first group of folders in the list is titled ``On This Computer.'' This set of folders are your \emph{local} folders\dash they reside on your computer only. If you use \acronym{POP} servers to retrieve your email, any new message will be placed in the \textbf{Inbox} local folder.

Below the folder list on the left side of the window are the \button{Mail}, \button{Contacts}, \button{Calendars}, \button{Tasks}, and \button{Memos} buttons. When working with email, the \button{Mail} button is selected. The other buttons take you to other parts of \application{Evolution}.

If your email provider requires authentication, select the \checkbox{Server requires authentication} option. This is common for commercial email providers. In the ``Authentication'' section of the screen, choose the type of authentication from the \dropdown{Type} drop-down list\dash the most common authentication type is ``\acronym{PLAIN}.'' Enter your username below, in the \textfield{Username} field, for example \textbf{joe.x.user}, or \textbf{joe.x.user@example.com}.

There are two common types of Internet email connections: \acronym{IMAP}, and \acronym{POP}. These are described below. In work environments there are sometimes other types, such as Microsoft Exchange or Novell GroupWise\dash for more information on those types of connections, please see the documentation for \application{Evolution}.

When \application{Evolution} starts you should see the \window{Evolution Setup Assistant} window, welcoming you to \application{Evolution}. Click \button{Forward} to continue with the setup.

\textbf{Purge}. This is when you wish to completely remove a package, including any stored preferences or configuration files (which are often left behind when a package is removed).

In the \window{Social accounts} window click the account that you want to remove and click \button{Remove}.

Click on one of the item categories in the sidebar to expand this category, and see the pages you've visited during that time period. Then, once you find the page you need, click on its title to return to it.

To see history from an older time, press \keystroke{Ctrl+H}. Firefox should open a ``sidebar'' on the left side of the browser window, which should contain your browsing history categorized as ``Today,'' ``Yesterday,'' ``Last 7 days,'' ``This month,'' and then monthly for the times before that.
