Re: 2 GPUs and 3 Displays
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.
