Bug Description
[Impact]
Currently, NVIDIA and modesetting drivers are using same output names, that creates confusion for xrandr clients like gnome-setting-
When modesetting outputs act as slave for other x-screen (like NVIDIA X-screen here), modesetting driver uses different scheme of output names to avoid kind of confusion we are seeing here. There is a bug in modesetting X-driver gets shipped with X-server, which disables slave output's name scheme.
From a reviewed upstream patch:
"Commit c7e8d4a6ee9542f
unifdef MODESETTING_
9257b1252da9092
so we need to backport that to zesty/yakkety/
[Test Case]
Enable dGPU, test that output to DP works.
[Regression Potential]
There should be none, as this leftover was a simple mistake that shouldn't be there.
