Chapter 4 Sun XVR-500 Graphics Accelerator Frame Locking 25
Configuring Sun XVR-500 Graphics
Accelerators for Frame Locking
1. Designate a Sun XVR-500 graphics accelerator as master for the graphics boards to
be in frame lock.
You can use the Sun XVR-500 graphics accelerator that serves as the boot/console
head for that system.
Refer to the
boot -r
man page for device location and device numbering
information for how devices are numbered based on their physical location. For
frame lock, you may select any device (that is,
ifb0
,
ifb1
,
ifb2
,...and so on) to be
the master Sun XVR-500 graphics accelerator device.
2. Make sure that each Sun XVR-500 graphics accelerator installed has the same
monitor resolution as the one in master mode.
a. Check the resolution of an Sun XVR-500 graphics accelerator by using the
fbconfig
command. For example:
You must repeat this command for each Sun XVR-500 graphics accelerator in the
system or systems.
The
fbconfig
command displays the current monitor resolution setting. It also
displays additional information such as whether the Sun XVR-500 graphics
accelerator is a master or slave.
b. (Optional) Change the resolution of a Sun XVR-500 graphics accelerator using
the
fbconfig
command.
If the resolution on each Sun XVR-500 graphics accelerator is not the same, you
must change it to match the Sun XVR-500 graphics accelerator in master mode.
For example:
If the resolution on each Sun XVR-500 graphics accelerator is not the same, you
must change it to match the Sun XVR-500 graphics accelerator in master mode.
