Created attachment 113043 [details] dmesg.log from kernel 3.18.5 I am currently running on kernel 3.14 Dell Latitude E7440 ( Intel Corporation Haswell-ULT Integrated Graphics Controller) With 3.14 I cannot connect my two external screens (DP and HDMI) on the doc, because then they get merged as one display. So I connect the HDMI to the notebook directly. This is supposed to be fixed in 3.18. 84718 and others I think it had to do with MST and in 3.14 I also saw errors that DP couldn't be train * [drm:intel_dp_complete_link_train] *ERROR* failed to train DP, aborting In 3.18 however when I start in the doc all screens are black. When I start outside the dock the eDP works but putting it into the doc nothing comes up on DP (dock) while connecting something to HDMI on the notebook itself still works. With not available I mean that xrandr shows disconnected. I originally thought this to be 87223 but was told to report a separate bug.
