    data: Enable wayland for single GPU vendor nvidia machines
    
    NVidia's wayland story is in a lot better shape these days, so
    disabling wayland entirely by default is a big too much.
    
    This commit changes the udev rule to just default to Xorg on single
    GPU nvidia vendor driver systems instead of disabling wayland
