I've used vagrant to set up ubuntu 12.10. How can I actually connect to the graphical desktop? There doesn't seem to be a way in the Virtualbox manager. It shows a preview but the 'show' icon is disabled.
It's a bit of a fiddle but I can suspend the vagrant then use the VirtualBox manager to start the VM and it connects to the display. I'd rather I didn't have to do this though because it might mess up NFS shares/IP addresses, etc.
