I have an NVIDIA Geforce GTX560 with two video projectors and I would like to use the onboard Intel Graphic Chipset to plug an additional monitor.

I saw the question : How can I use both Intel onboard and Nvidia graphics at the same time? but the answer is so short that I was not convinced.

My motherboard (GIGABYTE GA-H61M-D2P-B3 (rev. 1.0)) equipped with Intel H61 Chipset allow shared memory between onboard and PCIe cards. And Windows 7 allow me to use the three outputs thanks to Intel's driver.

I'm able to use the onboard graphic card but without graphical interface for now. I think i need intel driver for that.

But I would like to know if I can setup my displays in xorg.conf with something like :

Section "Device"
    Identifier "Device0"
    Driver "intel"
EndSection

Section "Device"
    Identifier "Device1"
    Driver "nvidia"
EndSection

Section "Device"
    Identifier "Device2"
    Driver "nvidia"
EndSection

Does anyone have successfully setup something like that ? Or should I burn my head experimenting it by myself ? Or is there any good reasons to discouraged me to try ?

Thanks for your help.

PS : i'm using Ubuntu 10.10 for now, but I could switch to another version.

PS2 : i also read this : Use 3 monitors w/built-in intel adapter + two old nvidia PCI cards on 10.10? which doesn't tell me more about the possibilities to use Intel Graphic and Nvidia at the same time

EDIT : according to that : Can not get Dual Monitors to work on Different GPUs, I should be able to run two Xserver one on Intel the other on Nvidia. I will try and post the result here.
