I installed Cinnamon on Ubunt 12.04 using:

sudo add-apt-repository ppa:gwendal-lebihan-dev/cinnamon-stable

sudo apt-get update

sudo apt-get install cinnamon

Now I am looking for a way to disable the keyboard shortcuts Alt + F7 (move window) and Alt + F8 (resize windows).

I already disabled those key bindings under Keyboard → Shortcuts. This doesn't have any effect.

I did not find them in gconf-editor under Apps → Muffin.

I already tried to disable them under Apps → Metacity → global_keybindings and window_keybindings which has no effect (although I thought Cinnamon uses Muffin and not Metacity).

How can I remove, edit, and disable those key bindings?
