echo -n Starting NVIDIA GeForce 310M...
modprobe nvidia

if [ "$?" -eq 0 ]; then
        # Count the number of NVIDIA controllers found.
        N3D=`/sbin/lspci | grep -i NVIDIA | grep "3D controller" | wc -l`

The official driver from http://www.nvidia.com for my Geforece 310M (on Acer Aspire 5745g laptop running Fedora Core 13 x86_64) does not work:

- X Windows does not work

- Opening /dev/nvidia0 brings error "Input/output error".

Trying another way: Unofficial Nvidia driver. Be sure to remove the official Nvidia driver before running step 1.
