[Bug 356850] Re: [UXA] xserver freeze while using firefox (UXA bug)

[Bryce Harrington]

** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  I was just opening up a firefox tab to fill out an apport crash report
  when X hung. The result of ubuntu-bug is attached; it starts up xkbcomp
  which never finishes here, so I had to kill that. Also attached is the
  gdb backtrace of Xorg process while it was hung, along with an
  inspection of some of the pointers at the deepest level that I could get
  debugging information for.
