I've just installed Linux Mint 13 Xfce (BEAUTIFUL distro/edition, by the way).

When I ran "Additional Drivers", there were two (2) that came up:
NVIDIA accelerated graphics driver (version current) [Recommended]
and
NVIDIA accelerated graphics driver (post-release updates) (version current-updates)
Please, do I have to choose which one to activate, or should I activate both?
Thank you very, very much.
Sincerely,
UUUnicorn
