Plasma wayland installation on Arch linux works for few seconds then black screen

Help
1

I installed plasma and when I run it on wayland, the first few seconds it runs fine then starts a loop, like unplugging and re plugging the screen again and again, or like changing screen input.

Added nvidia_drm.modeset=1 to the systemd bootloader option, also added MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm) to mkinitcpio.conf and ran mkinitcpio -P

Graphics card nvidia 3080, driver 565.77

Drivers installed:
lib32-nvidia-utils
lib32-opencl-nvidia
nvidia-open-dkms
nvidia-settings
nvidia-utils
opencl-nvidia

Thanks for your help

This is a question about configuring/troubleshooting your Arch installation properly. You can ask in their forums: https://bbs.archlinux.org

It’s actually a KDE bug:

Glad you found that it is a bug with specific monitors, it looks like it is an upstream issue with ddcutil though.
