After enabling an Ubuntu desktop for remote desktop connections (via the desktop sharing preferences), I am trying to gather how should I actually connect to it from a remote, other, Ubuntu desktop. I found no command line tools installed by default on my Ubuntu desktop for actually connecting to a remote desktop other than Remmina, or am just ignorant about them.
What is the most quality way to actually have a remote desktop session? (Ubuntu versions of interest are 13.10 and 14.04). Importantly, my target Ubuntu desktop is using the default unity desktop - I guess that may matter.
In this question I assume it's most straightforward to connect from a remote Ubuntu desktop, rather than a remote Ubuntu server (that typically won't have graphics libraries installed). And that it works best connecting from another Ubuntu rather than from, say, Windows. I just like Ubuntu desktops for now.
Since most questions here are about connecting from Windows, and focus on enabling the target desktop rather than how to connect to it, I figured I would post this question as a new one.
