Remote Desktop for Ubuntu
How to configure Remote Desktop on my office Ubuntu machine and how to connect to it from my Windows laptop at home?
Solution 1:
Take a look at: http://www.nomachine.com/
NoMachine NX is awesome because it gives you a remote desktop over ssh so it is a secure connection. You install the host on the machine you want to remote into and the client on the computer you want to use to control the other computer. They have versions of NX for Mac, Linux, and Windows, so you can remote from any O/S into any other O/S. It is really great free software, it will amaze you how well it works.
Solution 2:
The easiest way to do it is with VNC software.
Ubuntu has several options for VNC Servers.
As for the client on the Windows side, I've heard good things about RealVNC. It's a pay product, but they do have a free version.
