Hello. When I tried to unload the nvidia driver, I removed nvidia_uvm ans nvidia_modeset sucessfully. [image] However. I could not remove nvidia module because it is used by drm module. [image] How should I do to unload driver correctly ? Thank you for your help in advance.

It’s the other way round, the nvidia module is using the drm module, so that’s not the blocker. I’d rather guess you have some client running, locking the module. This might be either a display server (xorg/wayland) or simply the nvidia-persistenced daemon. Please check what keeps a hold onto the /…

Thank you for your suggestion. How could I do to check and unlock the client that keeps a hold onto the /dev nodes ?

i.e.: sudo lsof |grep "/dev/nvidia"

Excuse me. @generix @Mart This is the output results after I ran the command sudo lsof |grep “/dev/nvidia”. How should I do next ? This is the first part of the results nvidia-pe 37265 root 2u CHR 195,255 0t0 205 /dev/nvidiact…

This is the second part of the result nvidia-de 41730 root 12u CHR 195,255 0t0 205 /dev/nvidiactl nvidia-de 41730 root 13u CHR 195,0 0t0 206 /dev/nvidia0 n…

The application names are truncated but obviously many services are using the nvidia modules nvidia-pe… is the nvidia-persistenced daemon, like said, dcgm-ex(porter) is for prometheus monitoring, nvidia-de(???) for whatever. You should know what’s running on your system.
