Public bug reported:

Binary package hint: xserver-xorg-video-intel

I've been up to bleeding edge Version:
2:2.7.99.901+git20090617.b5cd2130-0ubuntu0sarvatt to try and get some
stability, but things are worse than ever.

Compiz is a white screen no go. Dropping down to Metacity gives me a totatlly
busy CPU core with Xorg running ~98% when anything major happens on screen (eg.
loading a page in Firefox). Typing in terminal doesn't seem to sweat X.


Kernel: "2.6.30-9-server #10-Ubuntu SMP Fri Jun 12 14:12:48 UTC 2009 i686 GNU/Linux"

The i915.ko is loaded, but has a use count of zero and I can rmmod it
whilst X stays running.
