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 including the
Sun XVR-1200 graphics accelerator.
Using Xinerama
When the window system is started in Xinerama mode, all windows can be
seamlessly moved across screen boundaries, thus creating one large, super high-
resolution, virtual display. With Sun OpenGL 1.2.3 and 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/config/Xservers
file.
For example, as superuser, type:
Note – For Sun Fire 6800 systems, use
local_uid@none
instead of
local_uid@console
when configuring the
Xservers
file.
There is some affect to performance when using Xinerama. “Setting Up Two Video
Streams Over One Large Frame Buffer” on page 35, in Chapter 5, describes an
alternative to Xinerama which in some cases may improve performance.
