I'm using xmodmap to swap control and command keys on my macbook pro. However, periodically the key revert back to their original state and this is becoming quite annoying. I'm on Ubuntu 13.10 and I can remember when this situation started occurring was when the system got a keyboard settings (in the system settings) update. Any ideas as to how to either: 1) delete the keyboard settings, or 2) stop the keyboard settings from reverting my keys ??? Cheers!
