Bug description:
Running with the proprietary nvidia drivers in an optimus config
works, but enabling reflection or rotation on the intel screen causes
a black screen to appear.
[Impact]
* Causes a black screen if rotation or reflection is enabled.
[Test Case]
* Run xrandr --output SOMEOUTPUT --rotation left
- Expected: Screen should rotate, or the call should fail.
- Bad behavior: Succeeds, but causes a black screen.
[Regression Potential]
* The affected codepaths have reflection and rotation disabled for gpu
screens. Another fix could be fixing reflection/rotation, but that will be more
involved and likely require driver fixes.
[Other Info]
* This issue is copied from
https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1308515 for vivid
and wily.
