Public bug reported:
With the open source radeon driver the system correcty resumes from
sleep, but after installing fglrx or fglrx-updates the screen is just
black when resuming. The computer hasn't actually hung so I can SSH to
it. At that point Xorg is using 100% CPU and I'm unable to kill or
restart the process (even when using kill -9). I'm not sure what to do
about this but I guess it should be possible to check what Xorg is stuck
doing.
