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]
   * N/A
