Chapter 3. Configuring X for the NVIDIA Driver
The X configuration file provides a means to configure the X server. This
section describes the settings necessary to enable the NVIDIA driver. A
comprehensive list of parameters is provided in Appendix D.
In April 2004 the X.org Foundation released an X server based on the XFree86
server. While many Linux distributions will use the X.org X server in the
future, rather than XFree86, the differences between the two should have no
impact on NVIDIA Linux users with two exceptions:
The X.org configuration file is '/etc/X11/xorg.conf' while the XFree86
configuration file is '/etc/X11/XF86Config'. The files use the same
syntax. This document refers to both files as "the X config file".
The X.org log file is '/var/log/Xorg.#.log' while the XFree86 log file
is '/var/log/XFree86.#.log' (where '#' is the server number -- usually
0). The format of the log files is nearly identical. This document
refers to both files as "the X log file".
In order for any changes to be read into the X server, you must edit the file
used by the server. While it is not unreasonable to simply edit both files, it
is easy to determine the correct file by searching for the line
(==) Using config file:
in the X log file. This line indicates the name of the X config file in use.
If you do not have a working X config file, there are a few different ways to
obtain one. A sample config file is included both with the XFree86
distribution and with the NVIDIA driver package (at
'/usr/share/doc/NVIDIA_GLX-1.0/'). Tools for generating a config file (such as
'xf86config') are included in many distributions. Additional information on
the X config syntax can be found in the XF86Config manual page (`man
XF86Config` or `man xorg.conf`).
If you have a working X config file for a different driver (such as the "nv"
or "vesa" driver), then simply edit the file as follows.
Remove the line:
(or Driver "vesa")
(or Driver "fbdev")
and replace it with the line:
Remove the following lines:
In the "Module" section of the file, add the line (if it does not already
There are numerous options that may be added to the X config file to tune the
NVIDIA X driver. Please see Appendix D for a complete list of these options.
Once you have completed these edits to the X config file, you may restart X
and begin using the accelerated OpenGL libraries. After restarting X, any
OpenGL application should automatically use the new NVIDIA libraries. If you
encounter any problems, please see Chapter 5 for common problem diagnoses.
