Complex mutli monitor setup

[Ben Edwards (lists)]

Hi,  I am setting up a computer to be used in a cinema.  We have a dual 
head Nvidia graphics card.  In windows it is easy to set it up so we 
extend the desktop and have different resolutions on watch monitor, is 
there a way of doing this on Ubuntu.

To go a little further into this one of the heads is connected to a 2k 
monitor.  It runs at a resolution of 2048x1080 and spooky windows 
recognises this EVEN WHEN THE PROJECTOR IS TURNED OFF!  Ubuntu seems to 
just go into mirror mode, it does not seem to recognise projector even 
if it is turned on;(.

Ultimately we need to mirror one display (the one connected to the 
projector) but have one used as a normal computer monitor.  For this 
there is a video out on the graphics card (would like to output video 
signal that mirrors the projector). The other option is to put in 
another graphics cards, I have one that has video, DVI and VGA out.
