NVIDIA Graphics Configuration
RedHawk Linux Version 5.4 Release Notes 57
The “Twinview” and “metamodes” options must be set in the xorg.conf Screen section.
See /usr/share/doc/ccur-nvidia-glx-190/README.txt for a detailed
discussion on Twinview.
7.3.5 Twinview-Xinerama
This mode enables multiple X Screens to join Twinview Screens as a single Desktop on
three or more monitors.
The “Twinview” and “metamodes” options must be set in the xorg.conf Screen section
for each supported device.
This also requires entries in xorg.conf to describe the layout of the Screens to the X
server and the setting of the server flag, “Xinerama” “1”.
The definition of the Xinerama server flag to X will override the ability of the Twinview
Screen to emulate Xinerama.
If you maximize a window in the Twinview Screen, it expands across both displays in the
Twinview Screen if not in clone mode.
If you maximize a window in a non-Twinview Screen, it fills that display.
7.3.6 Twinview-MultiDesktop
This mode enables multiple X Screens to join Twinview Screens as separate Desktops on
three or more monitors.
The “Twinview” and “metamodes” options must be set in the xorg.conf Screen section
for each supported device.
This also requires entries in xorg.conf to describe the layout of the Screens to the X
server and the setting of the server flag, “Xinerama” “0”, or by the omission of the
Xinerama server flag.
The definition of the Xinerama server flag to X will override the ability of the Twinview
Screen to emulate Xinerama.
If you maximize a window in the Twinview Screen, it will expand across both displays in
the Twinview Screen if not in clone mode.
If you maximize a window in a non-Twinview Screen, it will fill that display.
7.4 Using nvidia-xconfig
You must create /etc/X11/xorg.conf using the nvidia-xconfig utility before using
your system with the nvidia driver.
The nvidia-xconfig utility will generate some superfluous entries which you may choose
to remove. See the example xorg.conf file in section 7.6 for reference.
Follow this procedure exactly to generate the file:
1. Read sections 7.0. - 7.3 and complete any actions required.
2. Reboot to runlevel 3.
3. Move /etc/X11/xorg.conf to /etc/X11/xorg.conf.orig:
