Setting Up Video Output Methods
2.
Set the desired screen resolution. Type:
host% fbconfig -dev pfb0 - res 1280x1024x76
4.2.3
Setting Up Two Independent Video Outputs
This section allows independent resolution for each video output.
To set up two independent video outputs, do the following:
1.
To enable both video outputs, both devices
/dev/fbs/pfb0a
and
/dev/fbs/pfb0b
must appear in the
/etc/dt/config/Xservers
file.
As superuser, modify the
Xservers
file. For example, 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 -dev
/dev/fbs/pfb0a -dev /dev/fbs/pfb0b
2.
Select an independent screen resolution for each frame buffer. For example:
host% fbconfig -dev pfb0a -res 1280x1024x76
host% fbconfig -dev pfb0b -res 1152x900x66
Note:
Screen resolutions higher than 1280x1024 are
not
supported
for the DVI video port. (See
Table 1-2
, page 1-3, in Chapter 3 for
DVI-port-supported display resolutions.)
Note:
The use of two independent video outputs on a single board with Xinerama
is not supported. The X window system and Sun OpenGL for Solaris performance
may be noticeably degraded in this mode.
Set up two video outputs over one large frame buffer whenever possible for a dual
video output configuration. See previous section, "Setting Up Two Video Outputs
Over One Large Frame Buffer" on page 4-2.
