NVIDIA Dual Monitor Setup On Debian

I've had a search round and I can't figure this out.

This looks like it should work, however when X starts, I get the Nvidia logo on one of the screens, the other screen turns on as though its going to display the second screen, but fluxbox appears on the monitor that displayed the NVIDIA logo and the other monitor goes back to sleep state.

Can anyone see anyting wrong with my config.

Looking at this tutorial, although this is for Ubuntu. It looks likes

Option "TwinView"
Option "TwinViewOrientation" "RightOf"

Should both be under the Screen heading

Why don't you use the nvidia-setup utility that comes with the driver?

Thanks for the replies both.

I have tried the twinview option in the screen section. I get picture on one of the screens but the other does the same as with the above config. I checked both the monitors work ok as the primary screen.

I'm using the debian supplied driver, which is reccomended. and used the nvidia-xconfig utilitiy to create my xorg.conf

I might try the nvidia supplied driver and see if that helps
