Public bug reported:

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.
