Default Multiseat configuration with 7100GS

Hello,
I am trying to setup a multiseat configuration (two X servers two screens each having their independant sessions)
I am using the GeForce 7100 GS with two CRT screens connected to the VGA and DVI port of the card

I am unable to get the two screens working together with two X servers
I can either get one or the other working on but never the two together

I should also mention I have been able to activate the two screens simultaneously with classic dual screen setup (One screen on NVIDIA(0) one screen on NVIDA(1)) but I am unable to get it workingwith the two X servers
it seems each X server connects to NVIDIA(0)

does anyboby know if it is possible ? What am I missing?
Thank you

This is not possible. You can have a multiseat setup but you need to do it using one X server.

If you really want to separate X servers you'll need an additional videocard. The reason why what you tried doesn't work is because the Nvidia drivers are performing the 'card splitting' inside the drivers. Cards from other vendors can do it in a different way.

Thank you for your quick answers; how do I do a multiseat configuration with only one X server then?

You could of course have asked that question to Google
