load cuda modules cuda 2.3

The release notes say that “the CUDA module must be
loaded and the entries in /dev created. This may be achieved
by initializing X Windows, or by creating a script to load the
kernel module and create the entries.” Can I initialize X windows by typing “startx”? Can I put the script suggested in the xorg.conf file or make it a seperate macro to run when I want it or do I have to do it at boot time. Also there is mention that a display driver has to be installed. Is that the 190.18 driver or is there another one that I can use. I am new to Linux and Cuda and would appreciate any help.

If you start X, the /dev entries will be automatically created.
The script is for situation where X is not running ( like on cluster nodes).
