I am following this: https://wiki.archlinux.org/index.php/Nvidia#Installing

The command pacman -S nvidia fails with error: target not found: nvidia, indeed, even packman -Ss nvidia to search for it results in no matches, the only package found under extra that matches "nvidia" is extra/libcl.

My /etc/pacman.conf does have [extra] repository enabled (as can be seen in the search successfully finding one item in the extra repository).

Maybe pacman's list is out of date. I have run pacman -Sy.

This means that I'm completely stuck now.
