Title:
  nothing noticeable occurred computer just stated there was a gpu
  lockup

Status in module-init-tools package in Ubuntu:
  Invalid

Bug description:
  [Problem]
  The i915 kernel module seems to dislike having other kernel modules using the GPU.  In some cases i915 will do a GPU reset and fire off a "GPU locked up!" event.  The reset is successful and i915 carries on normally, so the user doesn't notice anything unusual and there's no symptoms other than the error messages in the dmesg log.  However, this is enough to trigger the apport GPU lockup reporting tool to pop up on a subsequent reboot and prompt the user to file a bug report.

  Essentially, module-init-tools (and other plumbing layer packages)
  don't always ensure a clean handoff between the vesafb driver and the
  i915 driver.  However, when you know that i915 is going to load
  properly, you don't really need vesafb anyway.

  [Workarounds]
  Use xdiagnose to disable the vesafb framebuffer driver.
  Or add it to the kernel blacklist.
  Or direct apport not to file bug reports for gpu lockups.  [This is the step taken for the natty release]

  [Original Report]
  Happens at every login. Not sure what is actually failing because everything seems to work fine.
