Description Bruno Cornec 2021-10-29 23:56:27 CEST

Description of problem:

Since some upgrades of mga8, KDE doesn't launch anymore, and I get a black screen with some KDE logo. Apps are running on the machine, but the Xorg server appears frozen. Unable to go to a terminal with CTRL-ALt-F2...

On the same system, LXDE works fine.

The culprit seems to be the nouveau driver as reported by this syslog entry:
