How to enable Ctrl+Alt+Backspace in Ubuntu 11.04

Hello everybody.

Sometimes we need to make some changes in Ubuntu that require restarting the X Server.

One way to restart the X server is running the following command in the shell:

sudo /etc/init.d/gdm restart

Another way to do that is configuring a shortcut Ctrl+Alt+Backspace that is disabled by default in Ubuntu.
In the terminal, type:

setxkbmap -option terminate:ctrl_alt_bksp

Now, to test that, hold Ctrl+Alt+Backspace to restart the X Server. However, to keep this functionality working for each Ubuntu startup, open the terminal and type:

gnome-session-properties

It will be opened a window like this one:

Click on add button and another window like this one will be opened:

Fill up for each field.

Name: Ctrl_Alt_Backspace
Command: setxkbmap -option terminate:ctrl_alt_bksp
Comment: Restart the X Server

Click on add button and after on close button. That’s it, all the time you start the Ubuntu and hold those keys, the X Server will be restarted.

See you next time.
