I don't know if there is a technical difference between a TTY console and a plain old terminal window? In the past I've assumed that TTY was less likely to be fouled by whatever was going on in your desktop instance, but it's just an assumption.

Certainly I have had times when I couldn't get a terminal window but TTY worked fine?
