[Bug 451697] [NEW] Xorg pegs CPU, desktop performance suffers after Karmic upgrade

[dmandell]

Public bug reported:

Binary package hint: xserver-xorg-video-intel

I'd been using Karmic for the last couple of weeks and did an upgrade to
get latest last night.  After a reboot I logged in and overall
performance was really lousy.  Scrolling from within a window, dragging
a window around, typing within a window were glacially slow.  Any time I
did any of the above things Xorg pegged the CPU. I tried rebooting
again, that didn't work.  I also tried rebooting and using an older
kernel, that also didn't work.

What managed to get everything back to normal was reverting from
xserver-xorg-video-intel_2%3a2.9.0-1ubuntu2_i386.deb to xserver-xorg-
video-intel_2%3a2.8.1-1ubuntu2_i386.deb.  After another reboot
performance was as it was before the update.  All other packages remain
as they are.

This is (apparently) not related to the cryptsetup version, I have the
most recent (fixed) version:

cryptsetup:
  Installed: (none)
  Candidate: 2:1.0.6+20090405.svn49-1ubuntu4
  Version table:
     2:1.0.6+20090405.svn49-1ubuntu4 0
        500 http://se.archive.ubuntu.com karmic/main Packages


I'd be glad to help debug this problem, but I probably can't do it during work hours because my laptop is more or less unusable for work while in this state.
