--------50-nvidia-drm-outputclass.conf------------

# This xorg.conf.d configuration snippet configures the X server to
# automatically load the nvidia X driver when it detects a device driven by the
# nvidia-drm.ko kernel module.  Please note that this only works on Linux kernels
# version 3.9 or higher with CONFIG_DRM enabled, and only if the nvidia-drm.ko
# kernel module is loaded before the X server is started.
