A new video card was added to a customer workstation. To get the new video card to work correctly, a systems administrator needs to remove support for the nouveau video driver on the Linux…

`rmmod -f nouveau` forcefully unloads the `nouveau` kernel module from the running kernel's memory. This immediately removes support for the driver, allowing for installation or activation of a new video card driver without conflicts.

`modprobe -R nouveau` is not a standard command for forcefully removing a module; `modprobe -r` is synonymous with `rmmod` but `rmmod -f` is more appropriate for forceful removal.

Adding `blacklist nouveau` to `/etc/modprobe.d/blacklist.conf` prevents the module from loading *at boot time*, but it does not remove an already loaded module from the current session.

`/etc/modprobe.conf` is an outdated configuration file; modern Linux systems use files within `/etc/modprobe.d/` for module configuration, and this method only prevents loading at boot, not immediate removal.
