From the little I know about Nividia nuances the symptom of a black screen 
points to KMS mode setting missing in the kernel.  Also nvidia_drm.modeset 
should be able to load without errors, or the wayland compositor will not 
work.  Also, I recall reading somewhere Nvidia does not like monitors with 
different resolutions and refresh rates, but I don't know if there is any 
workaround to this.  TBH I moved away from Xorg because it was getting worse 
and worse over time with my graphics.  Wayland was a bit unstable on my 
systems in the beginning, but over time it has improved significantly.
