Xinerama
3.2 Xinerama
Refer to the proper
Xservers
(1) man page and
Xservers
documentation for
further information. Xinerama is an X-window system feature available in Solaris 8
system software and subsequent compatible releases for Sun graphics boards includ-
ing the TGA-7000 graphics accelerator.
3.2.1 Using Xinerama
When the window system is started in Xinerama mode, all windows can be seam-
lessly moved across screen boundaries, thus creating one large, super-high resolu-
tion, virtual display. With Sun OpenGL 1.3 for Solaris, or subsequent compatible
releases, this functionality is extended to OpenGL applications. No recompilation is
necessary for a legacy application to work with Xinerama mode across multiple
screens, even if the application was compiled with an older version of Sun OpenGL
for Solaris.
• To enable Xinerama mode (single logical screen) on multiscreen displays, add
+xinerama
to the
Xsun
command line in the
/etc/dt/con-
fig/Xservers
file. See the following example.
For example, as superuser, type:
# cd /etc/dt/config
# vi + Xservers
Enter the
Xservers
file content in one long line.
:0 Local local_uid@console root /usr/openwin/bin/Xsun +xinerama -dev
/dev/fbs/pfb0 -dev /dev/fbs/pfb1
Section "Setting Up Two Video Outputs Over One Large Frame Buffer", page 4-2,
in Chapter 4, describes an alternative to Xinerama, useful in some cases, where per-
formance may be better.
Note: Be sure to enter
+xinerama
after
.../Xsun
in the
command line.
