Support question: Xorg multiple devices on one xorg Screen

[jaidormi]

Hi,

I use a window manager that supports only one xorg screen. Previously I had run two monitors from one card, which yielded a single xorg Screen object.

But now I want to run a third monitor from a second card. Is it possible to set up xorg.conf to get Card1 to draw on Screen 0? That is, two cards drawing to one logical Screen?

Thanks!
