How do I set up Video Bus for x-windows

walterbyrd · 02-21-2005, 10:56 AM

I'm trying to configure xfree86 for depian 3.1. I have built in AGP, but I am using my PCI expansion video card (GeForce MX 128MB DDR PCI).

xfree asks for a bus path such PCI:016:0. I have no idea what to enter, or how to find out. Any advice appreciated.

If you don't have multiple graphics cards, you can probably leave that empty.

You can usually leave that empty. It is only really needed with multiple graphics cards.

But if you'd like to fill in the value for it:
Execute

Code:

lspci | grep -i vga

That should produce output that looks something like this:

Code:

0000:03:00.0 VGA compatible controller: nVidia Corporation: Unknown device 00f1 (rev a2)

The numbers there in the beginning are the interesting ones. The first four zeros you can ignore, but the last three number units is the one you use.
In this case the PCI ID would be PCI:3:0:0

More generally, if the numbers there are 0000:X:Y.Z, then the PCI ID you specify in the X configuration is PCI:X:Y:Z
