Title:
Xorg 100% CPU usage (radeon, maybe compositing-related)
Status in “xserver-xorg-video-ati” package in Ubuntu:
Confirmed
Bug description:
Binary package hint: xorg
For the last couple of days, my laptop has been "freezing" after 0-10
minutes. Today I tried to SSH in and discovered that X was running at
100% on one CPU. Output of top:

This afternoon, I went about an hour without it happening, and I
decided not to report a bug. Then I tried to enable metacity
compositing (just to see what it was like; my hopes for enjoying it
weren't that high), and this seemed to cause the problem to appear.
I've got two more recent X bugs open. I'm starting to wonder if it's
me. If there's a diagnostic I can run to see if I have a hardware
quirk, I'd be happy to try it.
