I am running Mandrake 10.1 official. I installed the nvidia driver, edited my /etc/X11/xorg.conf file (which appears to be is a symlink pointing to the etc/X11/XF86config file) and replaced "nv" with "nvidia". When I restart the xserver I get the following message:

(ww) NV(0): failed to setup write-combing range (0xc0000000,0x4000000)
(ee) Failed to initialize GLX extension (NVIDIA X driver not found)

Apparently Mandrake is still trying load the old "nv" module not the "nvidia".
So to test my theory I did the following at the command prompt:

modprobe -r nv
modprobe nvidia
start x

I then got the NVIDIA logo screen and the NVIDIA driver worked. How can I fix it so that Mandrake doesn't attempt to load the old "nv" module but instead loads the "nvidia" module without me having to do the modprobe business shown above?

Never mind....Problem solved. I went into Mandrake Control Center and pointed Mandrake to the "nvidia" module.
