Is the nvidia-drm module loaded and its drm modesetting enabled?
E.g., via kernel cmdline option nvidia_drm.modeset=1
cat /sys/module/nvidia_drm/parameters/modeset should be 1 or "Y"
I think that isn't needed for PRIME outputs, but it is needed for the new PRIME sync to work, so maybe not yet part of the nvidia-prime package/setup.
Downside is that multi-gpu SLI wouldn't work anymore, but then i assume there aren't any Optimus laptops with two discrete NVidia gpu's, so that's a non-issue.
