This requires another computer  ( disadvantage ) but it is good for storing
messages for further processing ( advantage ) .

Are there any links to documents about how to pipe stdin , stdout , and
stderr outputs to such a sender - receiver facility before starting X by
"startx" ?

If we can use USB to VGA adapters , it will be easy and also old monitors (
or cheap LCD monitors ) may be used without requiring another computer .


Thank you very much .

This specific monitor use DisplayLink, according to the manual (there is one 
other standard too, but the name escapes me now).
OpenBSD has the udl driver: http://www.openbsd.org/cgi-bin/man.cgi?query=udl
AFAIK, nobody has ported that to FreeBSD.

Dears All ,

There are USB monitors , such as :

In FreeBSD , is there a possibility to attach such monitors for displays ?


A small possibility.  There was a thread in 2011 about getting 
DisplayLink drivers to compile.  As far as I know, USB monitors and 
external USB/DVI/VGA adapters both use DisplayLink.



My intention is to use Three such monitors to display

 . stdin
 . stdout
 . stderr

input - output values , with the regular display monitor in graphics mode
such as KDE4 .


Alternatively, that output could be sent out over serial ports.  But I 
think an easier and more reliable way would be to set up named pipes and 
netcat or something similar to send it to three different windows on 
another computer.
