Public bug reported:
[Impact]
* When using a hybrid graphics laptop with an external display connected on
startup, a black screen will show on the external display, or the server will
refuse to start if the resolution is > primary resolution.
* On nvidia 319 drivers in the prime configuration, the intel display will
stay black.
[Test Case]
* Connect an external display to the secondary video card, or use nvidia
drivers in prime configuration.
* Witness either a blank screen, or xserver failing to start. Correct behavior
is Xserver starting normally, displaying everything.
[Regression Potential]
* Patch has been in saucy for a while, no regressions happened there.
[Other Info]
* Commit dbfeaf70623a83e1a3f3255c94d52e0e04702837 upstream.
