[Leaplist] Remote Desktop Software advice?

[Chris]

Greetings,

I've got a customer interested in trying Linux. Up until now,
they've been a Windows shop. I've set up VNC on all their
desktops, and if they get in a bind, it's easy for me to attach
to their Windows desktop session and interact with them.

But it seems that VNC under Linux wants to create its own
session, which is not the same desktop that they will be seeing.
The goal is to be able to attach to their current desktop session -
not start a new one that they can't see.

Any ideas?

Cheers,

Chris
