X virtual frame buffer and -unmapped

["E. Mayorga" <emiliom@xxxxxxxxxxxxxxxx>]

I want to create GIF images in batch processes, when no X session is on.
ferret -unmapped has worked well when an X session is on, but that
restriction leads to other complications. I understand I need to install
the X virtual frame buffer, which is supposed to be a standard component
of X11. I've asked 3 system managers, and none of them have dealt with
Xvfb before (I found some relevant links on the web). I use Solaris 2.5 on
a SPARC 10.

Has anyone installed the Xvfb before? Where do I get it? Once installed
(any hints on how to do that?), how do I use it -- that is, does someone
have an example of the sequence of commands you would need to send a
ferret -unmapped [journal file] command to the Xvfb?

Alternatively, I understand that Ferret Vers. 5 will have this capability
completely wrapped into the "-batch" option -- does that mean Xvfb won't
be necessary? If so, maybe I should just wait for V5... ?

Thanks.
