Title:
i915, broadwell, cannot connect external monitor through Display Port
Status in xorg package in Ubuntu:
Incomplete
Bug description:
Hi, on new laptop (thinkpad t450s) I get error message after connecting
external monitor:
[drm:intel_dp_complete_link_train [i915]] *ERROR* failed to train DP, aborting
And after that, monitor is turned to sleep mode. Interesting thing is,
that monitor is detected.
