Setting Up Two Independent Video Streams
This allows independent resolution and sample density for each stream.
Note –
This streaming method is not supported in Xinerama on a single board. X
window system and Sun OpenGL for Solaris performance may be noticeably
degraded in this mode.
Set up two video streams over one large frame buffer whenever possible for a dual
stream configuration. See “Setting Up Two Video Streams Over One Large Frame
Buffer” on page 35.
To set up two independent video streams, do the following:
1. To enable both streams, both devices
/dev/fbs/jfb0a
and
/dev/fbs/jfb0b
must appear in the
/etc/dt/config/Xservers
file.
As superuser, modify the
Xservers
file. For example:
2. Select an independent screen resolution (and sample density, if desired) for each
frame buffer. Type:
# cd /etc/dt/config
# vi + Xservers
:0 Local local_uid@console root /usr/openwin/bin/Xsun -dev
/dev/fbs/jfb0a -dev /dev/fbs/jfb0b

fbconfig -dev jfb0a -res 1280x1024x76
