Bug Description

[Impact]
Currently, NVIDIA and modesetting drivers are using same output names, that creates confusion for xrandr clients like gnome-setting-daemon or xrandr utility.

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 c7e8d4a6ee9542f56cd241cf7a960fb8223a6b22 had already
unifdef MODESETTING_OUTPUT_SLAVE_SUPPORT but commit
9257b1252da9092ddc676fec9aabe2b33dfad272 didn't notice that."

so we need to backport that to zesty/yakkety/xenial.

[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.

This seems to have caused a regression with the unity8 test:

http://autopkgtest.ubuntu.com/packages/u/unity8/xenial/i386

Could someone have a look at this?

unity8 tests have always been brittle; the autopilot ones (which use X) succeeded, while the QML ones (which don't use X) didn't, so this appears unrelated.
