SUMMARY kwin does not set the configured monitor refresh rate on a fresh login. STEPS TO REPRODUCE 1. Login from SDDM (0.19.0). OBSERVED RESULT Monitor refresh rate is set to 60Hz (verified in monitor OSD). System settings has the monitor refresh rate set to 144Hz. Refresh rate must be changed to 120Hz and back to 144Hz to set the monitor refresh rate to 144Hz (updated refresh rate verified in monitor OSD). This must be done on every login. EXPECTED RESULT kwin to set the refresh rate on login to the configured refresh rate, in this case 144Hz. Operating System: Arch Linux KDE Plasma Version: 5.23.2 KDE Frameworks Version: 5.87.0 Qt Version: 5.15.2 Kernel Version: 5.14.14-arch1-1 (64-bit) Graphics Platform: Wayland Graphics Processor: AMD Radeon RX 6800 XT
Changing the refresh to 120Hz and reverting to '144Hz' also seems to work.
Changing to Kscreen. I've been doing some more digging and have found some strange behaviour using kscreen-doctor. When I log in and run 'kscreen-doctor -o', I get the following: Output: 1 GBT AORUS FV43U/21100B000422 enabled connected primary Unknown Modes: 0:3840x2160@144! 1:3840x2160@60 2:3840x2160@120 3:3840x2160@60 4:2560x1440@144 5:2560x1440@120 6:2560x1440@60 7:1920x1200@144 8:1920x1080@144 9:1920x1080@120 10:1920x1080@120 11:1920x1080@60 12:1920x1080@60 13:1920x1080@60 14:1600x1200@144 15:1680x1050@60 16:1280x1024@60 17:1440x900@60 18:1280x800@144 19:1280x720@120 20:1280x720@120 21:1280x720@100 22:1280x720@60 23:1280x720@60 24:1280x720@50 25:1024x768@75 26:1024x768@60 27:800x600@75 28:800x600@60 29:720x576@50 30:720x576@50 31:720x480@60 32:720x480@60 33:720x480@60 34:720x480@60 35:640x480@75 36:640x480@60 37:640x480@60 38:3840x2160@60* Geometry: 0,0 3840x2160 Scale: 1 Rotation: 1 Overscan: 0 Vrr: Automatic RgbRange: unknown primary Which says that I should be running at 3840x2160@144, but I'm actually only running at 38402x2160@60. If I set the refresh to 120Hz and revert to 144Hz, it fixes itself and I'll actually be at 3840x2160@144, but the output of 'kscreen-doctor -o' is: Output: 1 GBT AORUS FV43U/21100B000422 enabled connected primary Unknown Modes: 0:3840x2160@60 1:3840x2160@120 2:3840x2160@60 3:3840x2160@60 4:2560x1440@144 5:2560x1440@120 6:2560x1440@60 7:1920x1200@144 8:1920x1080@144 9:1920x1080@120 10:1920x1080@120 11:1920x1080@60 12:1920x1080@60 13:1920x1080@60 14:1600x1200@144 15:1680x1050@60 16:1280x1024@60 17:1440x900@60 18:1280x800@144 19:1280x720@120 20:1280x720@120 21:1280x720@100 22:1280x720@60 23:1280x720@60 24:1280x720@50 25:1024x768@75 26:1024x768@60 27:800x600@75 28:800x600@60 29:720x576@50 30:720x576@50 31:720x480@60 32:720x480@60 33:720x480@60 34:720x480@60 35:640x480@75 36:640x480@60 37:640x480@60 38:3840x2160@144*!
