Comment # 4 on bug 1191515 from Stefan Dirsch

Hmm. 5.14.6-2 is the kernel from the logfile on susepaste.org. Could you attach
the Xorg.0.log from the snapshot, where the monitor is still being detected?

Also I think we need the RPM package list, which has been updated/installed.
For this we would need the output of

  rpm -qa --last

from the current system and

  rpm -qa --last | head -n 1

from the snapshot where the monitor is still being detected.
