Is it possible to set up two different Gnome sessions to be started at boot time?
As it is now (and by default in any Ubuntu installation) a gdm login screen is presented after a few minutes of booting. After I log in, it's possible to use the "Switch user" functionality and have a second Gnome session running (for another reason). Then, both sessions are accessible by pressing Ctrl + Alt + F7 and Ctrl + Alt + F8.
Moreover it would be great if both sessions used different settings (different users) for automatic logging in.
