Xinerama / NVIDIA TwinView
The X.org extension supports continuous display technology on the X server for multiple card and
monitor configurations. When enabled, it changes independent displays to continuous displays.
● Xinerama—The X.org/XFree86 extension that supports continuous display technology on the X
server. When enabled, it changes independent displays to continuous displays. Xinerama is
configured with a ServerFlags option or enabled with a command-line option.
● TwinView—TwinView is an NVIDIA technology for creating/managing continuous desktop
regions that span multiple cards/monitors. NVIDIA cards recognize TwinView configuration
options to manage continuous desktops across screens hosted on the same card. The /usr/bin/
nvidia-settings configuration tool provides the most accurate and reliable management of these
options for multiple NVIDIA graphics cards.
30-bit (10-bit-per-channel) X Visuals
Except for NVS-series cards, NVIDIA Quadro® cards with G80 or later GPUs support internal circuitry
for 30-bit (10-bit-per-channel) color. Cards that support the DisplayPort connection standard can
generate signals to drive select high-color-gamut DisplayPort monitors (including the HP DreamColor
Professional Displays). These cards have higher fidelity than standard DVI-driven or VGA-driven
monitors that support 24-bit, 8-bit-per-channel signals.
Work to support 30-bit visuals on the enterprise desktop is ongoing with X.org X servers at X11 R7.4 or
later. (To correctly manage mixed 30-bit and 24-bit visual requests, these servers require later versions
of GDM , Gnome, and KDE display managers). For more information on these advanced settings, see
the documentation provided with the drivers and the Linux distribution.
AMD® / ATI graphics workstations
ATI™ provides a command line tool to automatically configure the Xorg configuration file /etc/X11/
xorg.conf. The aticonfig tool should be used immediately after the ATI graphics driver is installed to
perform the initial configuration of the xorg.conf file.
NOTE: The ATI graphics driver will not become functional until the following command is issued.
(Some driver installation packages run this utility automatically.)
# aticonfig --initial
HP recommends the Catalyst Control Center utility, an interactive configuration utility provided by ATI.
This utility provides access to:
● 3D Performance Management
● X Server Display Information and Management- including screen layouts, display resolutions and
timings, multi-display settings and Xinerama.
● X Screen # - including color gamma correction, XVideo settings, and Antialiasing requirements
● GPU # - including vbios version, clock speed, driver, and probed monitor information
Configuration changes can be previewed and saved by clicking Apply in the utility interface.
Additional documentation in html format is installed in the /usr/share/doc/ati directory.
