This is an update with regards to Wayland support and DRM fbdev.
Our newer driver releases going forward will have this information in the README.

        Wayland compositors may not be designed to handle the case where two
        DRM drivers instantiate independent device nodes capable of driving
        the same display. When the nvidia-drm driver does not remove
        conflicting framebuffers and instantiate its own DRM fbdev support,
        simpledrm will remain present for driving the initial framebuffer
        console if initially loaded. In this situation, both simpledrm and
        nvidia-drm have DRI device nodes driving the same display. This can
        lead to issues such as a black screen, corruption, or flickering. A
        workaround for this is to set the fbdev=1 module parameter for the
        nvidia-drm kernel module.
