Linux - The kernel module does not get loaded dynamically when X starts

The kernel module does not get loaded dynamically when X starts;

I always have to do 'modprobe nvidia' first.  What is wrong?

Make sure the line "alias char-major-195 nvidia" appears in

your module configuration file, generally one of "/etc/conf.modules",

"/etc/modules.conf" or "/etc/modutils/alias".  With 2.6 kernels,

this file is normally /etc/modprobe.conf.  The correct way to update

this file is distribution dependant, and it is often not a good idea

to edit this file directly.  Please consult the documentation that

came with your distribution for details.
