Question GPU in 2nd pci express slot not detected (as shown by lspci) (bodhi linux)


Hello all,

I've found several answers to others' questions here, but this is MY first post so I'm hoping I'll be able to get my issue resolved and learn a thing or three along the way. This issue I'm having is this:

I have 3 GPUs in my system: one on board (nvidia 8200), and two in pci-e slots (nvidia 8800gt / nvidia gtx460). Due to the way my xfx mobo is built, the 2nd (lower of the two on the mobo) pci-e slot is used to send monitor output when multiple cards are installed. I currently have my monitor attached to the 460 which is in that slot, and this is the card I wish to use (going to be running compiz-fusion).

The display is functioning (I'm posting from this pc right now) and it's connected to the 460, but if I run lspci, it only reports the 8200 and the 8800. I want to install the proprietary nvidia drivers, etc., but I want to make sure I'm operating on the correct card.

If possible, I'd like to avoid having to remove the 8800 as I use it in conjunction with the 460 when I boot windows for games.

What can I do to be sure the 460 is found by my system and is "selected" to be the main card for graphics processing?

Thanks!

Your opnboard VGA is disabled, actually this device:

is your GTX460.

Oh! Awesome! Well that makes me feel better...I was wondering how it could be using the monitor through that card if it couldn't find it!

Can I automatically assume then that linux is using this card as it's primary device? Is there a way to verify (just so I know how)?

You see your desktop, don't you? Therefore I would assume that it is your primary card.
