2 GPUs and 3 Displays

[entropathy]

Greetings,

I have an Asus M2NPV-VM MoBo with an onboard Nvidia chip...

00:05.0 VGA compatible controller: nVidia Corporation C51PV [GeForce 6150] (rev a2)

I also have a GeForce 6600 PCI-E card installed

03:00.0 VGA compatible controller: nVidia Corporation NV43 [GeForce 6600 LE] (rev a2)

I've been using the 6600 with 2 monitors for a while, and while poking in the bios saw that the mobo had the option to keep the onboard video enabled as well. So I thought I'd create a new X display and get 3 monitors going.

The nvidia-settings app recognizes everything like it should and the xconfig it generated works like I want , there is just one problem. The third display it very very dim, but it does function like it should, you can just barely make it out. I've tried several different monitors and verified it's what the port is putting out and not my cables or displays. Here is my X config, I was simply using the 2 ports on the 6600 in a twinview config and then just wanted the third screen for displaying status stuff, so it's fine as a seperate X display..any thoughts ?

Any help on whether this should be a viable configuration or not is much appreciated.

I have the same problem with my M2NPV-VM, although I have a GeForce 8600 GT PCI-E card instead and I'm running 177.70 (BETA).

With 169.12 I couldn't even get it working - I got an error about the BIOS on the onboard 6150. Now everything is detected and appears to be working, but the display on the 6150 (which is the secondary card) is so dim that it's unusable.

Did you ever find a solution? The same setup works fine under windows, so it is not a hardware problem.
