2. Set the desired screen resolution:
Setting Up Two Independent Video Streams
This procedure enables independent resolution and sample density for each stream.
Note –
This streaming method is not supported in Xinerama. X Window system and
Sun OpenGL for Solaris performance might be noticeably degraded in this mode.
Many resources (for example, color LUTs and WID entries) are managed
independently and the two streams compete with each other.
Set up two video streams over one large frame buffer whenever possible for a dual
stream configuration. See page 42.
1. Select an independent screen resolution (and sample density, if desired) for each
frame buffer:
You can mix any resolutions (
on page 10) at appropriate sample densities
(see “Multisample Antialiasing” on page 45).
2. To enable both streams, both devices
/dev/fbs/zulu0a
and
/dev/fbs/zulu0b
must appear in the
/etc/dt/config/Xservers
file.
As superuser, type:
3. Modify the
Xservers
file.
Enter the
Xservers
file content in one long line.
