Configuring Sun XVR-600 Graphics
Accelerators for Framelocking
1. Designate a Sun XVR-600 graphics accelerator as master for the graphics boards to
be in framelock.
You can use the Sun XVR-600 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
framelock, you may select any device (that is, jfb0, jfb1, jfb2,...and so on) to be
the master Sun XVR-600 graphics accelerator device.
2. Make sure that each Sun XVR-600 graphics accelerator installed has the same
monitor resolution as the one in master mode.
a. Check the resolution of an Sun XVR-600 graphics accelerator by using the
fbconfig command. For example:
You must repeat this command for each Sun XVR-600 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-600 graphics
accelerator is a master or slave.
