sometimes I get random desktop freezes, I can move the mouse and switch between TTYs but the desktop is unresponsive(looking for a way to diagnose this BTW), so I do
sudo service gdm restart this gives me my desktop back but I get a slow Compiz.
metacity --replace works fine but you know how it is :)
