Bug description:
  I just upgraded my Jaunty machine running Linux 2.6.28-16-generic to
  Karmic running Linux 2.6.31-14-generic, and noticed that KDE crashes
  back to the KDM login screen during startup. I can run Fluxbox just
  fine, and KDE works if I boot into Linux 2.6.28-16-generic. I can also
  startx remotely over Xephyr/SSH. Locally, however, I get the following
  error in kdm.log (and output during startx):

  Pro] (rev 01) video chipset with the xserver-xorg-video-openchrome
  driver, and the crash occurs whether I use an xorg.conf or not. The
  xorg.conf, if used, is
