Nope, that's not what Xvfb will do.  Xvfb will act as an X server for
applications that don't need to display something or accept keyboard
input from the user.  If you actually want something to show up on the
screen, it's not the right solution.

So my question now is: Why is the user working at a console instead of
in an X session?  It is pretty strange to startup an entire X session
every time you need to view an image.  If you want to have a
command-line inside X, use xterm or equivalent.  Make it fill the screen
and pick a big font, and it will look exactly like the console.  Except
your program doesn't need to worry about starting X anymore.
