Running Manjaro KDE Plasma on a standard tower PC, standard ATX board with a Ryzen 7 5800X3D, 32Gb at 3600MHz and a 3090, no over/under clocking. SATA SSD, secondary system alongside Win 11(separate drive).
I wanted to use wayland to enable HDR and try to play a video with mpv. Started off on the stable branch of Manjaro KDE, somehow wrangled it into working at 2am(bad idea) by following a bunch of arch wikis and jumping between posts here.
Changed nvidia.conf in /etc/modprobe.d :
options nvidia_drm modeset=1
options nvidia_drm fbdev=1
options nvidia NVreg_EnableGpuFirmware=0
options nvidia Nvreg_PreserveVideoMemoryAllocations=1
Changes in /etc/sddm.conf.d/10-wayland.conf
[General]
DisplayServer=wayland
GreeterEnvironment=QT_WAYLAND_SHELL_INTEGRATION=layer-shell
[Wayland]
CompositorCommand=kwin_wayland --drm --no-lockscreen --no-global-shortcuts --locale1
Enabled HDR with kscreen-doctor on DP-2(fully capable and supported)
“cat /sys/module/nvidia_drm/parameters/fbdev” returns Y
“cat /sys/module/nvidia_drm/parameters/modeset” returns y
From here on out, the video played and… looked good enough, I was to tired to care whether it was actually playing in HDR or not.
What I was completely ignoring due to sheer lack of mental energy was… this.
I am now stuck with a big, red text saying “Composing” that always snaps to the right top corner of the highest screen(I have a vertical 2 screen setup). If I disable the second screen, it sticks to the first one.
I decided to update the nvidia drivers from 550 to 565 by switching to the unstable branch and updating everything though the Add/Remove Software. This went swimmingly… except it did not fix the issue. I hoped it would. Bummer.
Alt+Shift+F12 doesn’t do anything either.
Anyway, tried to get rid of it by modifying a bunch of files, only to remove said changes and now be properly stuck at status quo, scared to touch anything. At least everything works properly, no visual glitches or lag.
Any ideas? Just hiding it would be nice…
