Xorg.0.lo

System is Thinkpad T460p with external display attached over DisplayPort.
Kernel is v5.0-rc2. Xorg is 1.20.3.

Xorg starts normally, but if external display gets through power cycle
switching to console and back leads to Xorg crash with "modeset(0): failed to
set mode: No such file or directory". See attached log.

The external display is Dell UP2414Q, which is 4k, but the bug can be
reproduced with MST disabled too.</pre>
