I am trying to run this command:

# rmmod nvidia

But I get:

ERROR: Module nvidia is in use

How can I know which process(es) is/are using the nvidia module?

There isn't a direct way that I know of to get the processes that are using a module.

You can try lsmod | grep <module name> to see all loaded kernel modules that are using a module.

You can also try dmesg | grep <module name> to see if the kernel logs have any clues as to which processes may be using a module.

You may be able to remove the module using rmmod --force <module_name>.

As for the nvidia module, you should be able to remove it if you shut down X11.

init 4
rmmod nvidia

worked for me.

For the nvidia module, this information can be retrieved by doing

$ sudo lsof /dev/nvidia*
[sudo] password for XXXXXXX:
