Hello,
I have recently bought two GTX280 for my system (x86_64, Fedora 9, kernel 2.6.27.9).
My problem is that I cannot use the second card in X.
I do:
/sbin/lspci | grep -i vga
01:00.0 VGA compatible controller: nVidia Corporation Unknown device 05e1 (rev a1)
02:00.0 VGA compatible controller: nVidia Corporation Unknown device 05e1 (rev a1)

deviceQuery reports only one device(device 0) out of X(runlevel 3), deviceQuery reports two devices.
nvidia-settings reports two devices in X.
What is the problem? What kernel option do I need to change or enable? What else do I need to do?
Thanks,
