I have a Lenovo X250 on my docking station with two external monitors, one connected via DVI and one via DP. The DVI works ok, but the DP doesn't even get listed in xrandr --query. If I use the HDMI port, it is listed, but the monitor remains blank (lack of bandwidth for the resolution?). > How often does the steps listed above trigger the issue? For example: always, 1 out 3 times. Always. -- system architecture: ("uname -m") x86_64 -- kernel version: ("uname -r"). Again, please consider using latest drm-intel-nightly from http://cgit.freedesktop.org/drm-intel (I tried to build it; it's an excessively long build and the final step (sudo make install) failed). 4.6.0-040600rc6-generic -- Linux distribution: Ubuntu 16.04 -- Machine or mother board model: Lenovo X250 -- Display connector: (such as HDMI, DP, eDP, ...)

In this configuration, I get my HP and built-in ok, but the BenQ doesn't show up at all (using xrandr --query). If I connect the BenQ via HDMI, then it shows up in xrandr --query, but the display is still blank (bandwidth issue?).
