sorry i misread your last post, one card two outputs, gotcha. Comes of
trying to cook at the same time, kick the dog out of the kitchen and
converse with an 11 year old dyspraxic whilst listening to my in house
jazz singer emulate tom waits.

Have you read the nvidia readme?

Heres the start of Chapter 15 on mine:

Chapter 15. Configuring Multiple X Screens on One Card
______________________________________________________________________________

GPUs that support TwinView (Chapter 13) can also be configured to treat each
connected display device as a separate X screen.

While there are several disadvantages to this approach as compared to TwinView
(e.g.: windows cannot be dragged between X screens, hardware accelerated
OpenGL cannot span the two X screens), it does offer several advantages over
TwinView:

   o If each display device is a separate X screen, then properties that may
     vary between X screens may vary between displays (e.g.: depth, root
     window size, etc).

   o Hardware that can only be used on one display at a time (e.g.: video
     overlays, hardware accelerated RGB overlays), and which consequently
     cannot be used at all when in TwinView, can be exposed on the first X
     screen when each display is a separate X screen.

--=----------------------------
The readme should be included in the packaging by your distro for the
nvidia drivers.
