Default Restrict X server to only one GPU?


Im having stability problems with a G210 on an Abit A-N78HD with built-on 8300 chipset.

To track down the issues, Id like the onboard chip to display the console and the PCIe card (G210) to show the X server (its an VDR system, so the card displays the video using vdpau).

The onboard card is the primary card in BIOS, so all console messages go here. The xorg.conf has been set up the bus id (3:0:0) for the PCIe card (internal is 2:0:0). However, the nvidia driver still uses both cards. The PCIe card will be enabled using the given configuration (dual head with an Epson EHTW3600 on HDMI and a Samsung LE32R32 on the DVI port). The other card is set up using a default configuration.

The main drawback is that the console is blanked as soon as the X server starts. I can only see console messages when swiching to the console usin Ctrl-Alt-F1, but then the video output is disabled.

Can I restrict the nvidia driver to only use the gpu mentioned in the xorg.conf by bus-id?
