Binary package hint: compiz

Since the last version, compiz randomly freezes X (only mouse cursor is
alive). System remains operational (I was watching a movie once when
that happened - I could hear it going on), but you can't even switch to
console. This happens randomly, but very often when something 3D is
happening. When I turn off desktop effects, there is no such freeze,
even when playing 3D games for a long time.

Hardware: GeForce 8600 GT (rev a1), driver: nvidia-glx-new (Ubuntu
package)

How to recover without hard reset:
Press Alt+SysReq+R to get the keyboard working again
CTRL+ALT+F1 to switch to console
pkill -9 compiz.real
will cause your X Server to restart.
All open apps will be killed, unsaved data will be lost!

** Affects: xorg (Ubuntu)
     Importance: Medium
         Status: Confirmed
