That version has reached EOL since a while, so it will not receive
update. If that issue still exist, report again using ubuntu-bug.


** Changed in: compiz (Ubuntu)
       Status: Incomplete => Invalid

Bug description:
  I am getting a full X server crash and restart in combination with the
  kernel error below:

      [drm:i915_gem_mmap_gtt_ioctl] *ERROR* Attempting to mmap a
  purgeable buffer

  and this error in the Xorg log:

      Fatal server error:
        Failed to submit batchbuffer: Invalid argument

  This occurs about once a day, and always when clicking on an entry in
  the bottom task bar; compiz is enabled.  Note that this is a Natty
  kernel in combination with Lucid userspace.

  Update: I just triggered the same apparent symptoms doing a shift-+ in
  a gnome-terminal.
