Re: Plasma 6 Wayland & nvidia , need to fix some Flickering

nvidia wayland anything needs the nvidia_drm.modeset=1 kernel parameter, make sure that's set up: https://wiki.archlinux.org/title/NVIDIA … de_setting

Generally better wayland support is expected for the next nvidia driver, currently in beta available via the nvidia-beta AUR package. To make full use of this you'd also need the explicit sync patch set which will ship with plasma 6.1 or can be preemptively attempted via kwin-explicit-sync that's also available in the AUR.

FWIW might want to disable the integrated AMD card in your UEFI so that doesn't interfere with general operation.

Disable it in your UEFI, otherwise blacklist amdgpu https://wiki.archlinux.org/title/Kernel … acklisting
