i just installed xtrlock_2.0-8_i386.deb (on sarge). After typing
"xtrlock" in a xterm, it was possible to change to the console (or
whatever this may be called) with Ctrl-Alt-F1. With the same user
logged in a "killall xtrlock" unlocked the X-Session.
So i thought it might be useful to mention in the manpage that there
shouldn't be any users logged in on the console if one wants to use
xtrlock (unless the underlying problem itself is solved, of course).
Thank you for providing Debian. There's nothing that comes close to.
