dmesg with the issue

Hello.

I'm getting the following in dmsg:

[drm:intel_dp_start_link_train [i915]] *ERROR* failed to enable link training

if I unplug my VGA display
Comment 1 kolp 2018-01-07 21:33:02 UTC 
This only seems to happen if I unplug the display, without disabling it via lxrandr. If I disable it via lxrandr then disconnect it, the issue doesn't show up
