Description Matej Starc 2022-12-24 13:37:09 UTC

SUMMARY
When I change any setting in display settings for a specific display, it freezes (the second on works).


STEPS TO REPRODUCE
1. Open display  settings
2. Change any setting (e.g., refresh rate)

OBSERVED RESULT
The screen that you changed settings for freezes, but you can still move your mouse into its place and can take focus (you can't do anything with it. Applications do not get launched.).

ADDITIONAL INFORMATION
coredumpctl has nothing to say about it. This might be an amd driver problem because I am getting a lot of crashes recently, and it is the only suspect I can think of.

Windows can still be moved to the other screen and they still take input.

Comment 5 Matej Starc 2022-12-24 13:44:14 UTC

Update: after one screen freezes, the second will too after 5 minutes. Then both will go black, and after that there will be no output for the displays (I have both my screens connected to my gpu).

Extra info: I tried connecting a monitor to my motherboard instead (I have an intel igpu) when I experienced the crash, and it did not output anything.

Sorry. Wrong bug report.

This should finally be fixed in Plasma 5.27, thank goodness.
