Regarding tty7, no. Technically logging in from gdm isn't a tty-based login at all - there's no terminal that you're typing commands into. But it's something of a convention to record the display number instead, so that commands like 'who' show graphical users as well as terminals. As for display :0, that always represents the primary display accessed by a user sitting in front of the machine - the normal situation for a desktop machine. Remote logins would use something else - depending on what methods they used, it might be just another number like :1 or :2, or it might be something like remote.machine.name:0. Simon.
