I have just put together a shiny new computer with a pair of EVGA 295, for some CUDA fun. The install and toolkit roll without a hitch, but the problem comes when I restart X, I get a rather ungraceful dump to the prompt. Examining my /var/log/xorg.0.log, it ends in a depressing:
(EE) No devices detected.
Where should I go from here?
On the plus side nvcc and the like appear to work normally . . .
Thanks.
Do the GPUs appear in lspci output?
Please generate and attach an nvidia-bug-report.log.gz while this problem is present.
Yes. Error log attached. Nifty util! Thank you.

I had something similar. Your xorg.conf probably doesn’t use the nvidia driver - or it doesn’t include the device identifier to which the monitor is connected. Does running nvidia-smi work? Then at least you know the driver is available correctly.
Any news or developments on this? Looks like I have the same problem
on the same setup (2 x EVGA 295, core i7 + 12GB DDR3). Worked fine
under Ubuntu 8.04, but no luck after 24 hours struggle with 9.04.
System dual boots with XP64, where everything is good.
Any suggestions? OpenSUSE? Patience??

If no display devices detected, maybe you need to specify which GPU was connected to monitor.
Add the following line into to section “Device” in xorg.conf:
BusID “PCI:n1:n2:n3”
where PCI:n1:n2:n3 is the device number of the GPU connected to the monitor, you can find it in the xorg.0.log file.
