Dual-Screen Mode
The Sun XVR-200 graphics accelerator has the ability to support two displays – two
digital displays, two analog displays, or one analog and one digital. You can
configure the card so that the two displays appear as one unified screen to the X
Windows display. In other words, windows can be easily moved between the two
displays (without the need for a special
xinerama
mode). This unified screen mode
is also called dual-screen mode.
The Sun XVR-200 graphics accelerator has only one graphic processor and two
DACs. The drawing engine is capable of driving both DACs. See “
X Window System
(Dual-Screen Mode) Configuration ” below.
Console Display Configuration
In console mode (that is, prior to starting the X Window System), only one monitor
head is used.
X Window System (Dual-Screen Mode) Configuration
You can configure graphics boards under the X Window System in either a single-
screen mode or a dual-screen mode, using the
fbconfig
utility.
●
To configure the graphics board to dual-screen mode, type:
When running
fbconfig
in the interactive mode (
fbconfig -i
), select
w
under the
OPTION
menu to enable dual-screen mode.
