Nvidia Dual monitors w/two video cards

Hi,

I am trying to configure two monitors with my Asus M2NPV-VM montherboard.

The onboard is a 6150 and in the PCI-E slot i have a 8400GS.

I am not sure if the board supports using both onboard and pci-e but there was a setting in the BIOS to enable PCI-E&Onboard.

When booted into CentOS 5.2 and running lspci i can see both cards:

Code:

00:05.0 VGA compatible controller: nVidia Corporation C51 [Quadro NVS 210S/GeForce 6150LE] (rev a2
01:00.0 VGA compatible controller: nVidia Corporation Unknown device 06e4 (rev a1)

here is a copy of the xorg.conf file i have modified:

Code:

When loading this xorg.conf file i get this error:

Code:

(WW) NVIDIA: No matching Device section for instance (BusID PCI:1:0:0) found
(EE) Screen 1 deleted because of no matching config section.

At this point GNOME loads on the montitor (onboard video). The odd part is if i comment out the onboard device's busID and start X i get this:

Code:

(WW) NVIDIA: No matching Device section for instance (BusID PCI:0:5:0) found
(EE) NVIDIA(1): Unable to find available Display Devices for screen 1.

So this tells me the driver can see both cards, as the GUI will load on each. But I cant load them both at the same time. Leading me to believe it wont work.

So, is it normally to be able to use both cards? Seems to me like if the board didnt support this you wouldnt see the onboard via the driver. Are there any mistakes in my config?

Thanks,
Mitchell

You should be able to get this working, my next step would be:

Remove the PCIE card and run X -configure, then save the /root/xorg.conf.new somewhere

Do the same for the PCIE card (disable onboard card in bios)

Then use the xorg-generated device sections and see what happens!

well, thats kinda what I did. I merged my old and new xorg.conf files from before i had the pci-e card and when i only used the pci-x.

Any other ideas?

I see... I take it each card performs perfectly on its own?

The only thing I noticed is this line:

Code:

Screen      0  "Screen0" 1920 0

When coupled with this line:

Code:

Option         "metamodes" "CRT: nvidia-auto-select +0+0"

Just for a test, try swapping the screens around and having everything at 0 0
So the server layout becomes:

Code:

    Screen      0  "Screen0" 0 0
    Screen      1  "Screen1" RightOf "Screen0"

And the PCI-E device becomes "Screen0"

no luck making those changes.

I can only assume that the bios is incapable of supporting this, try looking for a bios upgrade/fix!
