Comment 57 for bug 815996

Happened again, just after I posted the last message. Ran the dstack script posted above, but it never finished and tail revealed that it had only written a few insignificant lines to the compizstack.txt file. The dstack script ran fine when there was no freeze, but after the freeze the script would not complete.

I noticed that during the freeze, the X and gnome-settings-daemon processes are taking up the majority of the cpu resources.

For me, switching to a terminal and then back does not fix the problem. I always have to kill X.
