NVIDIA® Graphics Workstations
This section describes NVIDIA graphics configurations for HP Linux Workstations.
X Server configuration
HP recommends that you use the interactive configuration utilities provided by NVIDIA after you install
their accelerated driver packages.
If you use the HP version of the tested NVIDIA drivers, use the /usr/bin/nvidia-settings
command or click on the desktop icon to access the graphical utility.
This utility provides access to:
● X Server information
● X Server Display Information - includes screen layouts, display resolutions and timings, and
TwinView™ settings.
● X Screen # - includes color gamma correction, XVideo settings, cursor and OpenGL settings, and
Antialiasing requirements
● GPU # - includes thermal, power, and probed monitor information
Use /usr/bin/nvidia-settings to output a usable X server configuration file. This utility can
merge existing contents, write a clean file, or specify an alternate location so that the X -config startup
line can be used to test a configuration before accepting.
Additional documentation is installed in the /usr/share/doc/NVIDIA_GLX-1.0 directory. This directory
includes:
● README.txt—Complete NVIDIA features discussion and X server configuration options
● NVIDIA Changelog—Driver version release notes
● Sample X server configuration files.
SLI Graphics Acceleration
Dual PCIe cards can be linked together to drive a single graphics display to achieve up to two times
more performance of a single graphics card. This is accomplished through Scalable Link Interface™, a
card-bridge technology provided by NVIDIA. Only specific graphics card models support SLI™
technology, and SLI requires that the two cards be of the same type (homogenous configuration). For
more information on these advanced settings, see the documentation provided with the drivers.
