Description Antti Savolainen 2025-04-29 20:45:23 UTC 
Created attachment 180793 [details]
One display is uninteractable.

SUMMARY
Demonstrative video: https://youtu.be/U7esea8ZQa4
If I activate these three in some order, I can cause the display configurator to lock up or break completely. In the video I wasn't able to get a quick example, but it gets the point across. Sometimes it also causes situations like seen in the attached image. I've sent a couple of backtraces to sentry already

STEPS TO REPRODUCE
1. Mess around with the "Enabled" button, HDR button and Replica of dropdown

OBSERVED RESULT
The KCM crashes or gets messed up

EXPECTED RESULT
Normal function

SOFTWARE/OS VERSIONS

Comment 1 TraceyC 2025-04-30 22:58:16 UTC 
I know I've run into this in the last few days.

As a matter of fact, I also ran into a similar and potentially related problem today. I had been trying to get one of my two monitors to display something after waking.
The system was hard locked, I wasn't even able to get to a TTY. I had to power cycle the system.
There are no related coredumps listed by coredumpctl
Comment 2 TraceyC 2025-04-30 23:06:53 UTC 
Can you check kwin's logs when the bug happens? 

  journalctl --boot --user-unit plasma-kwin_wayland > ~/log.txt

Also, is there any chance that you could retrieve kwin's backtrace when the
bug occurs? Attach a debugger to kwin process like this:
  sudo gdb -p $(pidof kwin_wayland)

then type

  bt

and paste the output here. You would need to ssh from another computer and run this if the system locks up.

Thanks!

journalctl --boot --user-unit plasma-kwin_wayland > ~/log.txt

I have not been able to get the whole session to freeze. Only systemsettings display KCM. I have a gut feeling that it has something to do with getting the mirroring monitor to start use scaling so that it fits the larger TV and then turning it on and off.

For future reference, debuginfod doesn't work with sudo. I suggest switching to root and running gdb there

Comment 4 Antti Savolainen 2025-05-01 20:43:51 UTC 
I think I found a semi-reproducible way of getting the issue. This time systemsettings crashed an I got an backtrace of it. First you need to set a monitor to mirror the TV and then you need to change the resolution of the TV.
