Hi all,
FreeNX seems not to be anymore supported for newer systems (e.g. Oneiric) so I was very glad that I found this X2Go. Thanks for good work!
I got it running after I learned what to put into the session type and edited Wiki with my observation (http://www.x2go.org/doku.php/wiki:components:x2goclient).
There is a couple of small hitches though: The first is a small one; update, audio volume and network applets render a little badly (Mint 12 gnome classic fallback session).
The second is a little more critical; I don't have administration privileges in remote session. For example in Applications->Systems Tools->System Settings->User Accounts there is an Unlock button but it is disabled. So I can't use that tool to manage user accounts remotely. I don't know where to start to look at this problem.
