I can confirm that FreeNX works really well for speeding up Xwindows
connections, especially interactive ones. Alas, our sys-admins no
long allow it. Also alas, it's another software installation that you
have to do.

I wondered about the 64 bit - not sure if that is the problem so I'll
try to find a machine with 64bit windows to test.
The fact that even when it works it is slow is very discouraging. I'm
working with histology images that are at least 4Gb in size and I need
to be able to zoom in and out using jp2000 - perhaps the advantages of
using the linux box with 32Gb memory will be outweighed by the poor
display time!
Still the fact that it is possible is useful - at least I don't need
to search for another xwindows package!
Thanks,
Anne

I haven't seen the problem before, but I have been able to run
object graphics programs remotely from my LINUX box running IDL 7
to my Windows machine, running XMING. It is S-L-O-W. I use
SSH Secure Shell to log onto my LINUX box. I think the only
thing special we did there was turn on Tunnel X11 connections,
but you must have this working or you wouldn't see direct graphics
windows.
So, don't know, except that it is possible. :-)
Cheers,
David
P.S. Have you tried doing this to a 32-bit machine? I wonder
if something about the 64-bit is getting in your way?

Hi Anne
you can use the FreeNX server with unlimited users. http://freenx.berlios.de
NX is an exciting new technology for remote display. It provides near
local speed application responsiveness over high latency, low bandwidth
links. The core libraries for NX are provided by NoMachine under the
GPL. FreeNX is a GPL implementation of the NX Server and NX Client
Components.
It is compatible with the client from nomachine. I never used other clients.
cheers
