Bug Description
Every once in a while, usually when I've been reading news and blogs for a couple of hours, the display freezes up and doesn't respond to any mouse clicking. Doing ctrl-alt-backspace works as well as ctrl-alt-f1. I've noticed that if the problem happens a lot in a short period of time, eventually update-notifier will tell me updates are available. When I tried ctrl-alt-f1 and ran tops, that's when I discovered compiz was using 100% cpu so that was what was causing the display to not respond. I don't know many commands, but killall compiz did allow me to continue reading the blog, but of course all window decoration was missing and I had no way to launch other applications through the gui. After doing ctrl-alt-backspace to restore my desktop, Apport reported an update-notifier crash.
Since this problem happens at times I'm not doing anything but reading what's already in the browser and trying to scroll down to read more, I think the problem is caused by something done on a schedule. Since update-notifier always seems to come up eventually on reboot or ctrl-alt-backspace, it would seem like update-notifier is somehow causing compiz to use 100% cpu at times.

summary: |
- compiz uses 100% cpu seemingly at random but maybe related to update- - notifier + nouveau causes compiz and gnome-shell to use 100% CPU. nvidia-current + works. |
We need some stack information to help us determine the cause of the CPU spikes.
1. Download the attached dstack script to your home directory.
2. Log in to a virtual terminal (Ctrl+Alt+F1), and switch back (Ctrl+Alt+F7)
3. When the spike happens, switch to Ctrl+Alt+F1 and run this:
sudo -s
sh ./dstack compiz >> compizstack.txt
sh ./dstack compiz >> compizstack.txt
sh ./dstack compiz >> compizstack.txt
sh ./dstack compiz >> compizstack.txt
sh ./dstack compiz >> compizstack.txt
4. Attach the resulting compizstack.txt to this bug.
