CUDA 5.5 on Fedora 18 64bit ... X-Windows failure

Hello all,

I installed the RPM packages on a fresh Fedora 18 (64 bit) in a laptop with i7 and GeForce GT630M.
The opensource driver works perfectly, and also the installation process seems to be ok.
But when I reboot the machine X fails to start, because it seems the new driver doesn’t find any card!!!

If I look in /proc/driver/nvidia/gpus/0 I have this:

Model: GeForce GT 630M
IRQ: 16
GPU UUID: GPU-???-???-???-???
Video BIOS: ??.??.??.??.??
Bus Type: PCIe
DMA Size: 32 bits
DMA Mask: 0xffffffff
Bus Location: 0000:01.00.0

(just to be clear, it’s not an hw problem because under Windows 7 CUDA works perfectly).

The driver installed (with CUDA packages) is 319.37

Do you know is there’s some incompatibilities with such distro or some package ?


I’m assuming this is an Optimus laptop, in which case you’ll have to rely on Bumblebee or the newer kernel/drivers/xrandr that have native support for Optimus. If you peruse the Linux forum, you’ll find plenty of threads about it there.
