== <code>Ctrl+Alt+Backspace</code> Disabled ==
As stated in the [http://www.ubuntu.com/getubuntu/releasenotes/904 Ubuntu 9.04 release notes], Ctrl-Alt-Backspace key combination to restart Xorg is disabled.

<blockquote>
Ctrl-Alt-Backspace disabled by default in Xorg

The Ctrl-Alt-Backspace key combination to force a restart of X is now disabled by default, to eliminate the problem of accidentally triggering the key combination. Users who do want this function can enable it in their xorg.conf, or by running the command <code>dontzap --disable</code>.

</blockquote>

== Enable <code>Ctrl+Alt+Backspace</code> Again ==

* Open the <code>/etc/X11/xorg.conf</code> file and add
<pre>
Section "ServerFlags"
Option "DontZap" "false"
EndSection
</pre>

* Or simply use <code>dontzap</code>.
* If it is not installed already,
<pre>
$ sudo apt-get install dontzap
</pre>

* Use <code>dontzap</code> command to enable <code>Ctrl+Alt+Backspace</code>
<pre>
$ sudo dontzap --disable
</pre>

This acually adds
Section "ServerFlags"
Option "DontZap" "False"
EndSection
to the <code>/etc/X11/xorg.conf</code> file.

* After it is done, make sure to log out & in for the change to take effect.

* To enable the "DontZap" option again,
$ sudo dontzap --enable

* More information about the <code>DontZap</code> option.

<pre>
Option "DontZap" "boolean"
</pre>

This disallows the use of the Ctrl+Alt+Backspace sequence. That sequence is normally used to terminate the Xorg server. When this option is enabled, that key sequence has no special meaning and is passed to clients. Default: off.
