Still doesn't work for me, I did all the above including setting the vino preferences both as a user and as a superuser. When i connect I get a black screen, the desktop appears when I move the mouse, as soon as I move the mouse again the connection is closed. This happens with mate, cinnamon and the gnome desktops. This happens using vinigre and remmina, I also have ubuntu 12.04 installed, remote desktop works sort of, i can connect and use it but as soon as I closed a window I have to mouse over everything to clear the window from the desktop.
