I have my Ubuntu 13.10 desktop with vnc setup and installed. I'm using both a Macbook's integrated vnc remote desktop program and Windows 7's built-in Remote Desktop program to vnc. Both give the same results.
When I open the Remote Desktop application, I set up the vnc connection. It asks for IP address, username, and password. I plug all those in and click connect. After that, it tries to load,but never stops (I'm guessing, by default, vnc will keep trying to connect until it does). I've literally left it alone for hours, and it still hadn't connected. During this whole process, nowhere does it give me an error....not even a warning about something.
I'm able to ping and SSH into it, but it seems that Ubuntu doesn't like it when I vnc into it.
I don't know what else to say.
