Is it possible to run the onboard geforce 8200 from the motherboardat the same time with the addon 8600 GT PCIE?

Under Windows Vista I have no problem.
I am running 3 monitors in dual view mode fine.

Problem is I was running fine using the 8200 onboard, then I disabled it in the BIOS and installed the 8600 GT. Up to here all is fine.
But I decided to enable again the 8200 onboard with the 8600 GT and that was a bad idea, video craps outon mi I only get CLI (command line interface)

So I did the usual dpkg-reconfigure -phigh xserver-org, removed and reinstalled nvdriver, etc and still nothing only CLI.

So then I disabled in bios the geforce onboard 8200 and presto!
I got back into Gnome.

So wants next guys, any ideas how to use 2 GPU?
I know it does not matter here but in Windowz they run of the same unified architecture drive, so for Geforce 8 Series it's the same driver.

Before I reinstall from scratch I wanted to check with the pros.

Hi, I know it is possible, but you must setup /etc/X11/xorg.conf to enable it.

You can also use them in SLI mode or just use the onboard for physx and the pcie card for main processing.

Unfortunately, I have not done it.

You should be able to enable both chips, but boot to the pcie vga. the onboard will be used for physx (slaved).

My Motherboard is also marked as an gf8200 although it does not have a graphics chip on board (MCP78).

Hope this gives you some where to look, while you are waiting for a more concise answer from a guru here at LQ.

Thanks so much for the info!
my intention is if possible to use 3 monitors, i just will have to dig in the xorg conf file.

Now I know where to look.
