Im trying to get 3 screens working, one on my onboard AMD HD4200 and 2 on my Nvidia GT 430. I am getting 2 screens working, but I X is giving me an error. It says "Screen 1 was deleted because of no matching config section" Any Ideas?

Also, I can not use a tool like arandr because it does not recognize all of the monitors/devices.

Here is my xorg.conf:

#Section "ServerFlags"
#       Option  "xinerama"      "True"
#EndSection

Section "ServerLayout"
        Identifier     "X.org Configured"
        Screen      0  "MidScreen" 0 0
        Screen      1  "LeftScreen" LeftOf "MidScreen"
        Screen      2  "RightScreen" RightOf "MidScreen"
        Option  "Clone" "Off"
EndSection

I may be mistaken but if you combine discrete graphics with onboard, i think the onboard gets disabled, did you check its still enabled in bios? To be honest, your asking for trouble combining graphic solutions like that, especially when they are a combination of both AMD and NVIDIA products (unless you have a lucid chip of course).

If you are dead set on having a tri-screen setup, my advice to you would be to find a suitable graphics card with enough inputs to meet your needs.

It is not disabled. Right now I have one monitor on the NVIDIA card and one on the AMD card working, the VGA port on the NVIDIA card is not putting out any signal. I know it works though. –  Tyler Long Apr 16 '12 at 19:19
