[Bug 275809] Re: X lock-up when logging in from screensaver - crash in intelSwapBuffers()/ intelCopyBuffers()

[Bryce Harrington]

** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  Running Hardy updated as of today on a Thinkpad T61 with intel X3100
  graphics:
  
  $ dpkg -l | grep xserver-xorg-video-intel
  ii  xserver-xorg-video-intel   2:2.2.1-1ubuntu13.6  X.Org X server -- Intel i8xx, i9xx display d
  
  I occasionally run into X lock-ups where the desktop freezes, except for
  mouse. Not possible to Ctrl-Alt-F1 out to terminal. Laptop can be
  reached from ssh and it is seen that the /usr/bin/X process runs at
  almost 100% CPU. The Xorg.0.log contains repetitions of
  
   tossed event which came in late
   mieqEnequeue: out-of-order valuator event; dropping.
  
  Using compiz and have direct rendering enabled. Believe it is the same problem that is reported incomment
  https://bugs.launchpad.net/ubuntu/hardy/+source/xserver-xorg-video-intel/+bug/212799/comments/44
  
  and that it has something to do with was is reported in
  
  https://bugs.freedesktop.org/show_bug.cgi?id=14428
  
  Attaching Xorg.0.log.old that was active at the latest lock-up.
