  1. Go to System settings... -> Keyboard Layout -> Options...,
  2. unwind Miscellaneous compatibility options,
  3. check Special keys (Ctrl+Alt+<key>) handled in a server.

Please, be aware it will also disable some other shortcuts (e.g. ctrl+alt++ and ctrl+alt+- used to switch video modes).

Thanks for your help. In fact I was looking for Ctrl + Alt + F4 but I wrote Ctrl + Shift + F4 :( – Cedric Thiebault Apr 26 '12 at 12:49
