I can second what I mentioned elsewhere: This is *not* related to nouveau. Nor is it related to Compiz effects.
I get these symptoms maybe 10-20 per day: Screen freezes. Music/sound continues to work. Can move mouse but not click. Keyboard unresponsive. After maybe 10s the system comes back up. The hangs are seemingly random. Maybe slightly more likely to happen when system is under load. But can happen at any given time. I tried under Xfce, Gnome, and Unity. All environments display the symptom. And frankly, it's driving me nuts.
