NVidia on Compaq presario and video output

[Martin Marques]

A few months ago I had the unfortunancy of not being able to work with 
my Notebook and a projector which was connected to the video output.

The thing was that, or I had the LCD screen to see, or the I had to see 
on the screen of the projector.

How can I make my NVidia card work with both? Do I have to configure a 
dual head.

I'm on F7 with livna nvidia drivers.
