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 B, X Config Options.
The NVIDIA Driver includes a utility called nvidia-xconfig, which is designed to make editing the X configuration file easy. You can also edit it by hand.
The Solaris distribution for x86 comes with two X servers: Xsun and X.Org. Xsun is the proprietary X server developed by Sun Microsystems. The X.Org X server is released by the X.Org Foundation. The NVIDIA Accelerated SunOS Driver is enabled with the X.Org X server.
The installation process puts a sample X.Org configuration file
in /etc/X11/xorg.conf.nvidia.
An X.Org getconfig rules file, /usr/X11/lib/X11/getconfig/nvda.cfg, is also
installed. This configuration file will automatically choose the
NVIDIA X driver if the console device has the NVIDIA kernel driver
bound to it and no X.Org configuration file is found.
The X.Org configuration file is /etc/X11/xorg.conf. This document refers to this
file as “the X config
file”.
The X.Org log file is /var/log/Xorg.#.log (where # is the server number -- usually 0) This
document refers to this file as “the X
log file”.
In order for any changes to be read into the X server, you must edit the configuration file used by the server. 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:
Using nvidia-xconfig to configure the X server: nvidia-xconfig will find the X.Org configuration file and modify it to use the NVIDIA X driver. nvidia-xconfig will make a backup copy of your configuration file before modifying it.
A sample config file is included with the NVIDIA driver package
(at /usr/share/doc/NVIDIA/xorg.conf.nvidia).
Tools for generating a config file (such as xorgconfig) are included in the Solaris distributions.
Additional information on the X config syntax can be found in
the xorgconfig manual page (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:
Driver "nv"
(or Driver "vesa")
(or Driver "fbdev")
and replace it with the line:
Driver "nvidia"
Remove the following lines:
Load "dri"
Load "GLCore"
In the Module section of the
file, add the line (if it does not already exist):
Load "glx"
If the X config file does not have a Module section, you can safely skip the
last step if the X server installed on your system is an X.Org X
server or an XFree86 X release version 4.4.0 or greater. If you are
using an older XFree86 X server, add the following to your X config
file:
Section "Module"
Load "extmod"
Load "dbe"
Load "type1"
Load "freetype"
Load "glx"
EndSection
There are numerous options that may be added to the X config file to tune the NVIDIA X driver. See Appendix B, X Config Options 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. (NOTE: If you encounter any problems, see Chapter 7, Common Problems for common problem diagnoses.)
