Xorg will not use "nvidia" driver, how do I change?

first of all, have you downloaded the driver from the nvidia site, and 
ran the installer script?

you usually have to manually set up your xorg.conf file, which is very 
simple. the README file for this is provided on the support website, and 
with the installer package


heres a copy of the parts youre probably looking for, for your reading 


These configuration instructions assume that you have a basic XFree86 or
Xorg configuration file adapted for your system.

The XFree86/Xorg configuration file has a minimum of two sections that
are of particular interest:

 - the "Module" section
 - the "Device" section(s) corresponding to the NVIDIA device(s)

A typical "Module" section configured for use with the NVIDIA Driver Set
could look like this:

    Section "Module"
      Load  "bitmap"
      Load  "extmod"
      Load  "dbe"
      Load  "type1"
      Load  "glx"
      Load  "freetype"

Important: It is the 'Load "glx"' line which instructs the X server to
load the NVIDIA GLX XFree86/Xorg extension module. The "dri" and "GLcore"
lines, which are often present in auto-generated configuration files, are
not required, but shouldn't do any harm.

A typical "Device" section configured for use with the NVIDIA Driver Set
could look like this:

    Section "Device"
      Identifier  "Device"
      Driver      "nvidia"
      VendorName  "NVIDIA"
      BoardName   "GeForce2 Go"

Important: It is the 'Driver "nvidia"' line, which instructs the X server
to use the NVIDIA XFree86/Xorg driver module (nvidia_drv.o) for this
device. Most configuration utilities choose the open-source "nv" driver
(nv_drv.o) by default; if your XF86Config/xorg.conf has a "Device"
section with a 'Driver "nv"' line, you will need to change it to 'Driver

Please see the README for the NVIDIA Linux Driver Set for a comprehensive
description of available configuration options.



Similar to the NVIDIA Linux Driver Set, the user can decide if the NVIDIA
driver should use its internal AGP driver or if it should rely on the OS
provided AGP driver with the "NvAGP" XFree86/Xorg config file option:

 - Option "NvAGP" "0"       Disable AGP
 - Option "NvAGP" "1"       Use NVIDIA's AGP GART Driver
 - Option "NvAGP" "2"       Use the OS FreeBSD GART driver (agp.ko)
 - Option "NvAGP" "3"       Attempt "2", fall back to "1"

Unlike Linux, however, this option is not the only controlling factor at
this point; because of known problems, nvidia.ko is built without support
for FreeBSD's AGP driver by default. This behavior can be changed, see
nv-freebsd.h for details.

hope this helps;
