Reference Video Card BusID for xorg.conf
 

I currently have three graphic cards installed in a desktop, and I want Ubuntu to use only one. I understand I have to reference the BusID in the following format:

bus:device:function

The video card I want to reference is in:

pci bus 0x0002 cardnum 0x0b function 0x00 vendor 0x10de device 0x0326

I don't think any other information is needed, but it is a PCI nVidia GeForce 5500FX.

Can someone help me with the xorg.conf BusID for this device?

BusID should be shown if you use the lspci command.

Found it!
 

lspci gave the information that I had posted. I didn't know how to organize it at first, but I figured it out. I was using Hex characters instead of the base 10 number. I thought they were interchangeable, but I suppose not.

The command that really let me know what to do was x -(at this moment I've forgotten the parameter, sorry) but that listed the BusID's directly.
