<pre>Bug description:
When plugging in a displayport monitor it is not detected on this Thinkpad P50.
It is an nvidia/intel hybrid, and displayport works fine when the nvidia gpu is
enabled, but not when it is running in IGP mode with the nvidia disabled. This
same problem exists in 4.2 and drm-intel-nightly 20151016, and is the same if
hotplugging or booting when it already plugged in.
System environment:
-- system architecture: 64 bit
-- kernel versions: drm-intel-nightly 20151016, 4.2.0
-- xf86-video-intel: 2:2.99.917-1~exp1ubuntu2.2~trusty1
-- Linux distribution: ubuntu 14.04.3
-- CPU: Intel(R) Xeon(R) CPU E3-1505M v5 @ 2.80GHz
-- GPU: Intel Corporation Device [8086:191b] (rev 06) (prog-if 00 [VGA
controller]) + NVIDIA Corporation Device [10de:13b0] (rev a2) (prog-if 00 [VGA
controller])
-- Display connector: eDP, DP.
-- Monitor: Dell E1715S</pre>
