I'm coming from Fedora, where there's a useful package called "vnc-ltsp-config", which installs VNC so that it functions just like a normal Gnome desktop (i.e. it provides a login prompt, and then starts a new session for your user).
Does Ubuntu have anything similar to this? The normal VNC package appears to operate via the unuseful default, where you can only login to an existing desktop. How do you configure Ubuntu to create a new session when someone logs in via VNC?
