b. Change the resolution of a Sun XVR-4000 graphics accelerator using the
fbconfig
command.
If the resolution on each Sun XVR-4000 graphics accelerator is not the same, you
must change it to match the Sun XVR-4000 graphics accelerator in master mode.
You must configure each board separately (that is, for
zulu0
,
zulu1
, and so on).
The resolution shown below is an example only, you can use different video
formats such as
SUNW_STD_1600x1000x66
(
TABLE 2-1
).
Log out of the X Window system, and then log back in for the resolutions to take
effect. If you do not wish the framelock synchronization to be repeated when the
X Window system restarts, simply exit the window/desktop session instead of
logging out, or disable framelock (see “Disabling Framelock” on page 61).
3. Connect the framelock cables to each Sun graphics accelerator to be framelocked,
if you have not already done so.
Note – Do not enable any stream to be a slave without the framelock cable
connected. Be sure the framelock cable slave connector is attached to the graphics
board configured as a slave.
See the previous section “Connecting the Framelock Cable” on page 56.
Make sure to first connect the framelock cable master mode connector to the master
graphics accelerator.
4. Configure the master and slave devices for framelocking.
In this example,
zulu0
is the framelock master device, and
zulu1
is the slave
device.
On the Sun XVR-4000 graphics accelerator system, you do not need to run these last
two commands, setting each master and slave graphics board, each time you log into
your X Window system.
The video output from
zulu1
might glitch when framelock is enabled.
zulu1
output will then be framelocked. It will start frames when the framelock master
does.
