How to set keyboard combination to kill the X server?

  • 772

It used to be ctrl+alt+backspace to kill x server, but for some unknown reason, it was decided to disable that combination and use something else (I think it is right alt + printscreen +k).

So, how to enable ctrl+alt+backspace?

I have seen it can be done with installing dontzap, but I know there is a way to set that combination from system setup.

    Gnome:

    Open the keyboard preferences (Search for keyboard in Dash), go to the Layout tab and press Options. Open Key sequece to kill the X server and toggle Control + Alt + Backspace

    enter image description here

    KDE:

    I don't run KDE so I can't verify it or make a pretty screenshot, but according to the Ubuntu Wiki, you do as follows:

    • Open System Settings

    KDE 4.1 - KDE 4.5

    • Select "Regional & Language"

    • Select "Keyboard Layout".

    • Click on "Enable keyboard layouts" (in the Layout tab).

    • Select the "Advanced" tab. Then select "Key sequence to kill the X server" and enable "Control + Alt + Backspace".

    KDE 4.6+

    • Select Input Devices under the heading Hardware

    • Select Advanced Tab

    • Click on Configure Keyboard Options

    • Enable "Key sequence to kill the X server" and enable "Control + Alt + Backspace".

  2. If you are looking for a solution which is independent of Gnome/KDE/Fluxbox or any Desktop Environment or Window Manager, try the following. This command is part of the X Window System.

    From https://wiki.ubuntu.com/X/Config/DontZap#Using_the_command_line

    Using the command line

    You can type the following command to enable Zapping immediately.

    setxkbmap -option terminate:ctrl_alt_bksp

    If you're happy with the new behaviour you can add that command to your ~/.xinitrc in order to make the change permanent.
