from where to countthe number of NVIDIA controllers?

The file CUDA_Release_Notes_2.1_linux.txt

contains the text:

An example script (to be run at boot time):


modprobe nvidia

if [ “$?” -eq 0 ]; then

Count the number of NVIDIA controllers found.

N3D=/sbin/lspci | grep -i NVIDIA | grep "3D controller" | wc -l
NVGA=/sbin/lspci | grep -i NVIDIA | grep "VGA compatible controller" | wc -l

N=expr $N3D + $NVGA - 1
for i in seq 0 $N; do
mknod -m 666 /dev/nvidia$i c 195 $i;

mknod -m 666 /dev/nvidiactl c 195 255

exit 1

Question: in which file to include the above text and how to have it run each time to boot?

Thank you!

This is only needed when not running X.
If you need this, check your distribution on how to call scripts when initializing or changing a runlevel. In Fedora it will probably be runlevel 3 you need.
