NVIDIA Graphics Configuration
54 RedHawk Linux Version 5.4 Release Notes
7.0. NVIDIA Graphics Configuration
The Unified NVIDIA Linux Display Driver (version 190.42) is included in the RedHawk Linux
installation and built automatically for all pre-built and custom RedHawk Linux kernels. The
RedHawk installer probes for the type and model of video adapters present in the system, and
recommends installing the unified ccur-nvidia-glx rpm when it detects one or more
NVIDIA video cards present.
See sections 7.1 Supported NVIDIA GPUs and 7.2 Multiple NVIDIA Video Card
Considerations for more information on NVIDIA driver compatibility.
After you have installed the correct driver for your NVIDIA card, you must create a new
/etc/X11/xorg.conf to ensure the proper operation of the driver under X Window System
Version 7.1.1 and RedHawk Linux Version 5.4.
It is required to specify that X load the “nvidia” driver along with the appropriate modules in
xorg.conf. These entries will not be present in the default xorg.conf file created by the
installer. Follow the process described in section 7.4 Using nvidia-xconfig to generate the
new xorg.conf file.
After you have generated the new xorg.conf, follow the process described in section 7.5
Using nvidia-settings to configure your displays, whether single or multiple displays. The
types of display configurations are described in 7.3 Display Configurations.
You should create all new display configurations based on these processes. Failure to do so may
prevent the proper operation of your system.
Do not base any configuration on the xorg.conf file created by the install process or on any
other previous configuration you might have been using.
After you have completed the basic process for your display configuration, you can edit the
resulting /etc/X11/xorg.conf for final adjustments.
7.1 Supported NVIDIA GPUs
If the ccur-nvidia-glx rpm has been installed on your system, you can view the list of all
NVIDIA GPUs supported by the 190.42 driver in “Appendix A” in the following file:
/usr/share/doc/ccur-nvidia-glx-190/README.txt
Alternatively, you can examine the list of supported GPUs for driver 190.42 at the NVIDIA web
site which is located at:
http://www.nvidia.com
Note that if your NVIDIA GPU is not supported by the 190.42 driver, you will have to do one
of the following:
• replace the existing older NVIDIA card in your system with a newer NVIDIA card that is
supported by the 190.42 driver
• go to the NVIDIA web site mentioned above and download a legacy NVIDIA driver that
supports your NVIDIA card, and follow the installation instructions described on that
driver’s web page
