I am just wondering, because I do zypper dup in tty rather than an x-terminal, but that also means whenever I am leaving my laptop unattended, the tty session can be easily accessed by someone knowledgeable about the process, because the x screen lock does not lock out access to the tty screen as well. Someone could easily cancel my command, and have access to my user-level privileges. Does anyone know of a way to lock out the tty session automatically after the x screenlocker is invoked?

You can run zypper in screen (actually you /should/ run zypper in screen) and lock screen then.

Understood. Thanks for the suggestion!

Screen has a facility for locking it? I use tmux, I haven't noticed such a feature. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

And if you use screen (or tmux) you don't need a separate tty session.

I typically start a tty session, start a new tumx session, then go back to X, and there attach to the same session. You say this is not needed? If I create the tmux session on the desktop only and this one dies, tmux survives? -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

That's the point of it, but I only know about screen.
