SUMMARY Changing refresh rate from 60hz to 144hz resets after rebooting back to 60hz. STEPS TO REPRODUCE 1. Reboot 2. Go to system settings, open Display And Monitor -> Display Configuration 3. Change refresh rate from default (60hz) to something else (144hz) 4. Reboot 5. Go to system settings, open Display And Monitor -> Display Configuration 6. Refresh rate has reset to 60hz, both visibly and in settings configuration OBSERVED RESULT Refresh rate switches back to the default 60hz, both visibly and in settings configuration EXPECTED RESULT Refresh rate would stay in the saved setting (144hz), both visibly and in settings configuration SOFTWARE/OS VERSIONS Operating System: Kubuntu 21.10 KDE Plasma Version: 5.22.5 KDE Frameworks Version: 5.86.0 Qt Version: 5.15.2 Kernel Version: 5.13.0-21-generic (64-bit) Graphics Platform: X11 Processors: 12 × AMD Ryzen 5 3600 6-Core Processor Memory: 15,5 GiB of RAM Graphics Processor: AMD Radeon ™ RX 480 Graphics ADDITIONAL INFORMATION If there are way to find logs for this, tell me and i'll do that. SDDM is always 60hz, maybe that could be the reason?
I partially "solved" the issue by setting my SDDM do the following in `/usr/share/sddm/scripts/Xsetup` ``` xrandr --output DVI-D-0 --mode 1920x1080 --pos 0x0 --rate 144 --primary xrandr --output DisplayPort-0 --mode 1920x1080 --rate 143.85 ```
Thank you for the bug report. Unfortunately we were not able to get to it yet. If this is still reproducible with Plasma 5.26, can you: 1. undo that change 2. reboot 3. Set up the refresh rate as you expect 4. paste the output of `kscreen-doctor -o` 5. reboot 6. paste the output of `kscreen-doctor -o` again Thanks a lot!
I do not have same setup as before and I haven't encountered this bug for long time. Current setup works as expected, the refresh rate does not reset between reboots.

Awesome. I suspect it was a driver bug all along, FWIW.
