After I updated to Plasma 6.2.3-1, the external monitor is blank again. It seems to be "detected" as in my laptop screen flickers for a moment, there is the detection sound, and windows apparently open on the monitor. However, the monitor itself remains completely dark and after a few seconds it starts its connection detection cycle.

The same NVidia driver was working just fine with Plasma 6.2.2.
Any suggestions what to try this time?
I am kind of disappointed with all these external monitor issues that started to happen early this summer and I see it is like working for a week, not working for another week. I hope things will stabilize soon.

Downgrade helped for now. Here is what I did:
cat /var/log/pacman.log | grep '2024-11-06T09:2' | grep -i upgrade | grep -vE 'chromium|mpg123|gnutls|libelf|full system' | sed -e "s/.*upgraded\s*/\'/;s/ (/=/;s/\s*->.*/\'/" | xargs -I{} downgrade --latest --prefer-cache --ignore never {}Last edited by patkoscsaba (2024-11-06 08:20:39)
