Hi,

Follow Modinfo relational

Look at this (10-nvidia.conf)

Section "Files"

    ModulePath "/usr/lib/x86_64-linux-gnu/nvidia/xorg"

EndSection

Section "OutputClass"
    Identifier "nvidia"
    MatchDriver "nvidia"
    Driver "drm"
    Option "AllowEmptyInitialConfiguration"
EndSection

Section "OutputClass"
    Identifier "nvidia-uvm"
    MatchDriver "nvidia-uvm"
    Driver "nvidia"
    Option "AllowEmptyInitialConfiguration"
EndSection

Section "OutputClass"
    Identifier "nvidia-drm"
    MatchDriver "nvidia-drm"
    Driver "nvidia-modeset"
    Option "AllowEmptyInitialConfiguration"
EndSection

Section "OutputClass"
    Identifier "nvidia-drm2"
    MatchDriver "nvidia-drm"
    Driver "drm_kms_helper"
    Option "AllowEmptyInitialConfiguration"
EndSection

Section "OutputClass"
    Identifier "nvidia-drm3"
    MatchDriver "nvidia-drm"
    Driver "drm"
