I’m trying to use CUDA on my workstation, and I’m running in to trouble when I add a 9800 X2 card for CUDA. The machine specs are as follows:
Intel Core 2 Quad Q9450
ASUS P5E3 Motherboard
4 GB DDR3 RAM
Fedora Core 9 OS (x86_64)
Linux -x86_64 177.13 Driver
CUDA 2.0b2 (x86_64)
In the top PCIe x16 slot, I have a GeForce 8800GTS. With this in place, I can run two monitors, and also run CUDA on the 8800GTS. This part is working fine (I know that FC9 is not officially supported).
Recently, I was given a 9800 X2 card, which I’d like to dedicate to CUDA. I’ve installed this in the second PCIe x16 slot, and put in a new PSU (which gives green lights on both power hookups). However, when I try booting the machine, X fails to start, booting text-only instead. Furthermore, theLooking at lspci, I find
[font=“Courier”]01:00.0 VGA compatible controller: nVidia Corporation GeForce 8800 GTS 512 (rev a2)
02:00.0 PCI bridge: nVidia Corporation Unknown device 05be (rev a2)

04:00.0 3D controller: nVidia Corporation Unknown device 0604 (rev a2)
05:00.0 VGA compatible controller: nVidia Corporation Unknown device 0604 (rev a2)
If I try issuing a ‘startx’ command, it fails with an error “No devices detected” I have tried reinstalling the driver, but that did not help. If I unplug the power cables from the 9800, everything goes back to normal (although the 9800 is obviously not present).
Any suggestions would be greatly appreciated.
