Description Alex 2021-11-02 00:10:36 UTC
This is a new bug to track 438839, which apparently hasn't been fixed, according to comments. Normally, I would mark that bug as re-opened, but David Edmundson specifically requested to create a new bug with new logs if there are still issues.

I'm having this issue with Plasma Wayland 5.23.2 on Arch Linux.
Turning the screen off, and back on again with the button on the back makes plasmashell, konsole, dolphin and other kde apps crash.

This is the log file I captured with journalctl -f | grep --line-buffered kde

Nothing really different from the others it seems.

I'm having the same issue with Plasma 5.23.2 on Wayland.

After turning screen off then on I get this from plasmashell:

Comment 3 ltstarwarskid 2021-11-02 15:04:03 UTC
Can confirm is an issue on 5.23.2 for me as well. I would post the backtrace, but after plasmashell crashes drkonqi isn't stable, and I haven't been able to get the logs.

It repeats the last four lines basically for as long as the monitor is off in my logs.
