Ubuntu is a popular distribution of the GNU/Linux operating system. Ubuntu is in turn based on the Debian distribution of Linux. By default Ubuntu uses the GNOME desktop environment, though it is also possible to use KDE or Xfce. The desktop environment is fairly easy to use even if you have no previous experience with Linux. For more information about Ubuntu, and to download a Live CD, visit http://www.ubuntu.com This page tells you how you can install the BOINC client software on Ubuntu (and how to uninstall it, if you so desire).

==Basic installation==
You can easily install the BOINC client software on Ubuntu Linux to run as a daemon, which autostarts the BOINC client at boot time, and to put a BOINC Manager icon on the applications menu.
Simply open a Terminal window (via the menu ''Applications -> Accessories -> Terminal'') to get a command line (aka "shell") and give the following command:
<code>sudo aptitude install boinc-client boinc-manager</code>

If you are familiar with the [https://help.ubuntu.com/community/SynapticHowto Synaptic package management system] you may use that instead to install these two packages.

== Non-graphics installation==
If you have a "headless" computer with no graphics then you do not want or need the BOINC Manager.
In this case just install the client by itself, with the command
<code>sudo aptitude install boinc-client</code>
See also the page [http://boinc.berkeley.edu/wiki/Stop_or_start_BOINC_daemon_after_boot Stop or start BOINC daemon after boot] in the BOINC User Manual Wiki for helpful commands for controlling the daemon.

==Starting BOINC==
After the installation is finished, the daemon is started automatically.
You can then start the [http://boinc.berkeley.edu/wiki/BOINC_Manager BOINC Manager] from the pull-down menu ''Applications -> System Tools -> BOINC Manager''. The first time you do this you will be prompted to attach to one or more BOINC projects.

After the installation is finished the daemon is configured to start up automatically every time the computer is turned on.
You can temporarily disable or re-enable this by modifying a setting in the file ''/etc/default/boinc-client'':
# Set this to 1 to enable and to 0 to disable the init script.
ENABLED="1"

At present it seems that you cannot control the BOINC "service" via the graphical interface, but this may become possible in future releases of the BOINC software.

==What the installer does==
# Puts the BOINC binaries (boinc, boinccmd and boincmgr) in ''/usr/bin'' .
# Creates a configuration directory /etc/boinc-client containing files ''cc_config.xml'', ''global_prefs_override.xml'', ''gui_rpc_auth.cfg'', and ''remote_hosts.cfg'' (It is a Debian convention that such files live under ''/etc'')
# Creates the working directory ''/var/lib/boinc-client/'' for BOINC data files and the slots and projects directories. Also creates links from this directory to the files in ''/etc/boinc-client''
# Creates a user named ''boinc''. For improved security, this ''boinc'' user owns the BOINC working directory and all the data files and sub-directories created under the working directory.
# Creates the daemon "init" script, ''/etc/init.d/boinc-client'', and a set of configuration options for the daemon at ''/etc/default/boinc-client''
# Sets up the daemon to autostart at boot time.

For more information about configuring BOINC in Linux, see [http://boinc.berkeley.edu/wiki/Linux_file_permissions Linux file permissions] in the BOINC User Manual WIki.

==CUDA==
If you want to use CUDA, install it as described here: https://help.ubuntu.com/community/Cuda .

==Uninstall==
To remove BOINC from the computer you can use the ''aptitude'' command to remove the packages you installed earlier. The command is:
<code>sudo aptitude remove boinc-manager boinc-client</code>
Removing the BOINC Manager may also remove other packages if they are no longer used, such as ''libwxbase'' and ''libwxgtk''.

The "remove" command only removes executable files and turns off the daemon, but it does not remove configuration files or the working directory. This can be either good or bad, depending. It means that if you re-install BOINC later you will have the previous configuration. It also means that the disk space used by the working directory is not reclaimed.
To completely remove BOINC from your system use the "purge" command instead:
<code>sudo aptitude purge boinc-manager boinc-client</code>
Because issuing the purge command will remove all project data and any work you have in progress, you will be prompted to confirm this action before it is actually carried out.

Again, if you are familiar with the [https://help.ubuntu.com/community/SynapticHowto Synaptic package management system] you can use that instead of ''aptitude'' to either "remove" or "completely remove" these packages.
