Hi,
I want to know how I can modify the default keybindings on my Ubuntu 12.10 system using Unity window manager.
I want to disable 'move window' keybinding ALT-F8 and ALT-F7.
I changed it in keyboad->shortcuts but every time I reboot my machine the default settings seem to be back.

Does somebody has got an idea what I can do ?

thank you,
detlef
