** Description changed: - From a private bug: - "Currently, NVIDIA and modesetting drivers are using same output names, that creates confusion for xrandr clients like gnome-setting-daemon or xrandr utility. + [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." + 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.
