Bug ID: 437973
Summary: Meta + P Switch Monitor Shortcut Reverts Monitor(s) to
Default Refresh Rate
Product: kwin
Version: 5.21.5
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: xrandr
Assignee: kwin-bugs-n...@kde.org
Reporter: dodgexan...@gmail.com
Target Milestone: ---
SUMMARY
Using the Meta+P shortcut to change multiple monitor layouts sets monitor
frequency to default instead metamode defined in xorg.conf, or if not, it
should use the last used frequency.
STEPS TO REPRODUCE
1. Set a monitor refresh rate that is non-default, in my case 144hz of my
external monitor.
2. Change screen layout using meta+p shortcut to extend too secondary screen.
3. View current refresh rate (reported by the display).
OBSERVED RESULT
The refresh rate always switches to the default as reported by xrandr, rather
than the preferred mode set in xorg.conf, or the last used mode in
nvidia-settings or display manager. For monitors that have correct refresh
rate's set as default, its fine. For high refresh rate monitors that often
report default 60hz when they can run at 144hz+ or higher, its not.
When using Meta+P you can view the xorg.log. Instead of following my defined
metamode in the xorg.conf, meta+p overules and sets the resolution as an auto
mode instead.
See xorg log when I enable my internal laptop monitor in addition to my primary
here (extend right, meta+p):
[ 17023.529] (II) NVIDIA(0): Setting mode "DP-1: nvidia-auto-select @2560x1440
+1920+0 {ViewPortIn=2560x1440, ViewPortOut=2560x1440+0+0}, DP-0:
nvidia-auto-select @1920x1080 +0+0 {ViewPortIn=1920x1080,
ViewPortOut=1920x1080+0+0}"
DP-1 which is my ext monitor is using nvidia-auto-select mode and not the
metamode reported in my xorg.conf.
EXPECTED RESULT
The shortcut should read the preferred mode set in xorg.conf, or the last used
mode rather than the default mode.
Correct Xorg.log would look like:
[ 17023.529] (II) NVIDIA(0): Setting mode "DP-1: 2560x1440_144 +1920+0
{ViewPortIn=2560x1440, ViewPortOut=2560x1440+0+0}, DP-0: 1920x1080_120
@1920x1080 +0+0 {ViewPortIn=1920x1080, ViewPortOut=1920x1080+0+0}"

them.
