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

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 dependent, and it is often not a good idea to edit this file directly. Please consult the documentation that came with your distribution for details.
