I use a good deal of the default Ubuntu shortcuts as shortcuts in Emacs (Alt-Space is the most important). I obviously have disabled these shortcuts in the keyboard shortcuts dialog, but for whatever reason, they sometimes "come back", generally after I've installed/uninstalled certain packages, or upgraded Ubuntu.

My question therefore is: how do I keep these shortcuts disabled? I don't want shortcuts like Alt-Space restored for any reason.

  • No one? :( I did a software update (no new installed packages) and again Alt-Space as well Ctrl-Alt-Arrows have reappeared. So annoying. Feb 4 '13 at 9:16
  • Agreed! Maybe you can add something to your login script.

  • That is one of the reasons that I use fluxbox as my window manager. There, the keyboard shortcuts can be edited in a text file and moved around different machines.

There are several ubuntu bugs in launchpad about keyboard shortcuts settings being reset to default.

It seems that when you switch the 'Backend' setting to 'Flat-file Configuration Backend' in CompizConfig Settings Manager under 'Preferences', the keyboard shortcuts changes seem persistent. You'll have to do a unity --replace for the changes to take affect.

  • Thanks for pointing out this 'Backend' option. Can you please edit your answer to tell us where the 'flat files' are stored?

Try gconf-editor then search for the keybinding under Edit -> Find search also in key values
You should be able to find your keybinding here, then unset it or change it to something else

  • this does not answer the question
