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

[Kees Cook]

To clarify, this is not bug 439138 since the CPU would idle when not
doing anything (and cryptsetup is not installed).

** Description changed:

  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

- 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.
