Yes you will have to. There are 2 problems (as far as I can see on my
laptop (Toshiba qosmio)):

1- toggle LCD only, beamer Only, both. This is done with some Fn-F* key
and this must be done *before* loading the nvidia driver ie. you have to
do it during the "grub" sequence.

2- you must have a specific xorg.conf with twinview enabled.

I'll send mine to night (here) and how I built a mean to switch from one
xorg.conf (lcd-panel) and xorg.conf (lcd+beamer) if you need it.
