How to disable Ctrl+Q system wide?

I read the other answers but they did not help. Reassigning the shortcut is not possible, since pressing the key combination quits the settings window, so it does not have any effect.

Thanks in advance.

  • Like I said in the question "... pressing the key combination quits the settings window, so it does not have any effect". Did you tried it yourself at all? – peter Oct 15 '12 at 13:02
  • The first answer worked for me, with no workarounds. Maybe it got fixed in newer Ubuntu versions? Anyway, +1'd. – Gui Imamura Sep 8 '16 at 2:21
  • Also, no reboot/relogin/whatever required, it worked out straight up. – Gui Imamura Sep 8 '16 at 2:24

open dash and choose desktop shortcut

Then go to shortcut tab and there press at +(add) sign to add a new shortcut

On the name write anything and for command write /bin/false which means do nothing in really then assign Ctrl+Q as its shortcut.

enter image description here

This actually make Ctrl+Q execute command /bin/false which means nothing

    Whenever I try to assign [Ctrl]+[Q] to the new shortcut the Keyboard program closes. – AnnanFay Dec 10 '12 at 22:02

Answering my own question !

I got it. Create a new shortcut to /bin/false as previous answer mentioned, but assign something else than Ctrl+Q to it , since you cannot do that. Ctrl+J might be good. Restart computer. Open the file /home/$USER/.gconf/desktop/gnome/keybindings/custom0/%gconf.xml in a text editor. And look for:

<entry name="binding" mtime="1350630493" type="string">

and in the


change the last letter of the text between the tags from the lowercase equivalent of what key you assigned before rebooting to "q". So it ends up as


Save, reboot, done.
