Public bug reported: 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.
