I've logged into a TTY (the VGA console) after boot, did a 'startx &'
and quit the login shell. Root (me again) has his own shell in an xterm
inside my X session.

So no one is still logged into a TTY, but I'd think that, since these 2
users are doing stuff, they should be seen as logged in (further
research shows that they *are* seen if logged into a TTY).

Interesting. I don't know much about this topic, so any pointers are
welcome.

Thank you,
