how to use remote desktop on ubuntu

I'm trying to use the "Remmina Remote Desktop" application that came with my Ubuntu 14.0.4 (64 bit) install to connect to another ubuntu desktop. But anytime, I try to connect, I get the message: "unable to connect to RDP server myservername". I haven't "enabled" anything on the other server that I'm trying to connect to. Do i need to do that?

Yes:

1. you need to enable it.

   Go to the dash (or from a terminal) and run vino-preferences (It is called "Desktop sharing" in the dash):

   It should be almost self-explicative.

and

2. The connection type is VNC, not RDP.
