I connect to mine using Tightvnc, works fine. I just need to know the IP of the box I want to remote into, make sure Remote desktop is of course set up on the other box, and away I go.
What issues are you having? What are you trying, and what is happening?
I usually install Vino and Vinagre to enable remote desktop viewing and setup, but the basic remote desktop seems to have issues, so I use Tightvnc instead to log into my other machines, and it's not a problem at all.
Remember this, the only stupid question is the one you don't ask.
"The thing about changing the world... is that once you do it, the world's all different."
Let's share our knowledge. Otherwise, what's the point?
