Comment 2 for bug 1888193

This looks like a hardware or driver problem with the Radeon Pro WX 7100. Your logs show two issues:

1. Xorg logs that the monitor is being repeatedly redetected. So it sounds like the monitor is not plugged in properly. Maybe try a new monitor cable.

2. The kernel is logging more serious issues:
