Ubuntu: Ctrl-Alt-Backspace Disabled By Default
Most Linux distro updates being released in 2009 will be using the latest version of X. Unfortunatly, they have disabled the Ctrl-Alt-Backspace keystroke by default due to complaints by users (even though it’s been there for years).
Here’s how to re-enable it….
Open a terminal and use the su command to get root privilages or add sudo before the following command-
gedit /etc/X11/xorg.conf
At the very bottom of the file, start a new line and copy-paste in the following:
Section “ServerFlags”
Option “DontZap” “false”
EndSection
Log out and back in again (or do a full restart of your computer) and Ctrl-Alt-Backspace will now work
(Tested in Ubuntu and Fedora)
