FK <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|WAITINGFORINFO |--- Status|NEEDSINFO |REPORTED --- Comment #4 from FK <[email protected]> --- No worries. I'm not really sure. I still get plasmashell hanging when my display becomes unavailable/available, see log below with ddutil 2.2.1 and plasma 6.4.4. I have three displays connected. Main configuration is the TV connected through HDMI, which takes a little while to get online when powered on (through button press or WOL) when returning from screen blanking. This results in the system realizing: "hey, this display isn't available, let's switch to the configuration with the two other displays" then getting the connected information and switching back to only the HDMI. When the alternative displays aren't available the system just insta-suspends when I turn on the TV. Sometimes plasma then just hangs and needs to be restarted through systemctl --user restart plasma-plasmashell, in the log it restarted on its own.
