A bit. ;-)

There is no USE flag "nvidia-settings". The USE flag is called
"video_cards_nvidia" resp. VIDEO="nvidia". It's both the same. In
make.conf you usually set VIDEO="nvidia", but you can also set or unset
USE="video_cards_nvidia" in make.conf, package.use or wherever instead.

VIDEO="nvidia" automatically sets USE="video_cards_nvidia" in the
correspondent ebuilds.
