[LUGSB] Changing Display of Running App

[mad about you]

Try xmove -- it can do most of what you'd like it to.
xmove acts as a Xserver to the programs you run with its display, and
as an X program to the display you forward its output to. It can
switch around from one to another fairly well (with some minor
limitations, such as font transfers between X servers, and tray
applets).

I had some problems with an early version of it, but based on your
question I decided to explore again and have been using it with no
problems for the past few days.

What I generally found myself doing, though, when I spent more time
away from my local machine, was simply keeping a tightvncserver
running with whatever I wanted to keep open, and connecting to it
through SSH wherever I went, including when I *was* at my local
machine.


A particularly handy trick I put together was a web page on my server
with 3 frames: 1, download tight vncviewer.exe 2, download
sparky.ssh2, a saved session file for the SecureSSH Shell or whatever
program it is they're using for SSH in the school labs, that included
my color preferences of white on black, and port forwarding to my home
machine for SSH only 3, port forwarding through the forwarded SSH for
VNC.

Made a few visits to www.hopto.org, and voila! blah.hopto.org opens a
web page, three confirm messages pop up and when the appropriate three
clicks are made, I type in localhost:3 and a few passwords to get to
my portable desktop, which always contained GAIM, email, and a
browser. Plus I'd have two handy shells which often I appreciated
being separately available. YMMV.
