Ubuntu – How to disable Ctrl+Q for all applications (system wide)


A lot of applications like Firefox, Chrome etc, get closed when I accidentally press Ctrl+Q instead of Ctrl+W because of the proximity of the Q and W keys on the keyboard. Is there a way this shortcut can be removed or reset on a system wide basis?

The best way is to disable the keyboard setting in your specific application. For Firefox there is an extension keyconfig. This allows you to change keyboard settings.

If you want to disable Ctrl+Q for your whole system, I would suggest to make a new setting:

  1. Go to System -> Preferences -> Keyboard settings
  2. Click Add
  3. Give it a name like fake setting and enter /bin/false as command. Apply your changes.
  4. Click on 'Disabled' and press Ctrl+Q.

Now you should have a new entry with your applied name and your keyboard setting. Every time you press Ctrl+Q your system will run the command /bin/false which basically does nothing. So this is a workaround to disable the setting.
