To Set Up Two Video Outputs Over One Large
Frame Buffer
This enables two monitor support without the use of Xinerama software. This
means that the Sun XVR-300 x8 graphics accelerator creates one wide (or tall)

doublewide
mode.
1. Enable both video outputs, sharing a single frame buffer. Type

Use the
-doublehigh
option for displays that are set one above the other (rather
than side-by-side as for the
-doublewide
option). Both monitors must have the
same resolution.
■
Use the
-outputs swapped
option to reverse the positions of the two video
outputs relative to each other. The default is
direct
. Both monitors must have
the same resolution.
