Re-Enable Ctrl+Alt+Backspace for Ubuntu 9.04 (Jaunty)

May 19, 2009

Linux only: The latest version of Ubuntu disables the easiest way to restart X Windows—but the Ubuntu Geek blog has instructions to easily enable the shortcut key combination again.

Normally using the Ctrl+Alt+Backspace shortcut key combination will immediately restart the X server and bring you back to the login prompt—an extremely useful tool when testing xorg.conf changes for your display setup—but the latest version of Ubuntu has removed this ability to prevent new users from accidentally triggering a restart. The Ubuntu Geek guide explains how to very quickly set the behavior back to defaults—simply install the dontzap package and use the following command:

sudo dontzap --disable

Hit the link for the explanation, or if you want the opposite for an older version of different distribution of Linux, I’ve written an article on how to disable the Ctrl+Alt+Backspace shortcut combination from restarting X.

Do you find the ability to quickly restart X a useful tool or a too-easily-triggered annoyance? Tell us in the comments.
