Hi guys,
We are about to use Z68ITXBE (ZOTAC with NVidia GT 430 onboard) is our appliances based on linux (kernel 2.6.38) .
For the moment we are trying to make available such configuration:
Use only NVidia card, to one analog display is connected to DVI-I (via dvi-vga adapter), second one is connected to Display Port
In this configuration only first display is available. Second one is in standby mode.

In /var/log/Xorg.0.log there are such lines:

(EE) Feb 22 09:50:37 NVIDIA(1): The requested configuration of display devices (DFP-0) in
(EE) Feb 22 09:50:37 NVIDIA(1): MetaMode "640x480" is not supported on this GPU; none is
(EE) Feb 22 09:50:37 NVIDIA(1): recommended, instead.
(WW) Feb 22 09:50:37 NVIDIA(1):

(WW) Feb 22 09:50:37 NVIDIA(1): "nvidia-auto-select".

(EE) Feb 22 09:50:37 NVIDIA(1): Unable to use default mode "nvidia-auto-select".
(II) UnloadModule: "nvidia"

When we use both video out in digital mode it's OK. There is no errors in log file and both displays work.
xorg.conf and full Xorg.0.log are attached

I'm trying to get the same machine to work. Though I don't have a DisplayPort adapter as of yet. Once I get that DisplayPort->HDMI I might want to discuss this further.

I've tested with even 3.3 kernel and never got a signal from the Nvidia card (from the DVI out, DisplayPort still untested). Which drivers were you using for Nvidia?

I just get "GPU has fallen of the bus" from nvidia driver, occasional freezes with certain settings, nouveau driver causes some major error. Otherwise the boars seems to work.

Which BIOS settings did you use? I have the newest BIOS.
