linux (ubuntu 9.04) with 2 devices installed

hi!

can someone tell me how to install the driver of nvidia in linux (ubuntu 9.04) with 2 devices installed? (9500GT and GTX 295)
when I try the “normal” way get the error “No screens found”

I had this problem too, with 9800GTX+GTX-260, 2xGTX60 and 2xGTX280 - it is independent of the cards used, but depends on where among the PCI devices the card with a display attached is located.

In my present case - lspci says

01:00.0 VGA compatible controller: nVidia Corporation G80 [GeForce GTX 260] (rev a1)

02:00.0 VGA compatible controller: nVidia Corporation G80 [GeForce GTX 260] (rev a1)

and the monitor is attached to the card in PCI slot 02:00.0. I also have to set in my BIOS that my monitor is attached to slot PEG2, otherwise I do not get to see anything (not even the POST BIOS messages). Then /etc/X11/xorg.conf I have the following setup shown below:

Section “Device”

Identifier     "Device0"

Driver         "nvidia"

VendorName     "NVIDIA Corporation"

BoardName      "GTX260"

BusID          "PCI:2:0:0"

Option         "Coolbits" "1"

EndSection

Please, note that the crucial part is:

BusID “PCI:2:0:0”

Try that and see what happens - of course you should know at which PCI Bus ID the card with the monitor is located.
