By default Ctrl + Alt + BackSpace key combination in Ubuntu Jaunty was disabled.This shortcut key is used  to restart X.This tutorial will explain how to enable this key combunation.

Install the “dontzap” package using the following command

sudo apt-get install dontzap

Open Terminal and type

sudo dontzap --enable


sudo dontzap --disable

Where “disable” means that Ctrl+Alt+Backspace restarts the xserver while “enable” means that it won’t.

Section “ServerFlags”
Option “DontZap” “false”

right alt + printscreen +k
