In another lifetime (early RedHat days, I think. Maybe Minix, probably not) I could customise the LogIn screen's welcome message using a variety of escape codes & EnvVars. (Just to clarify: I'm talking about a msg displayed statically on the LogIn screen, not the motd or welcome msg displayed once a user logged in!)
%nfor host name or
%tfor system time, etc., as well as a similar set for formatting. CR's, NL's etc. It may even have been more like
$TIMEbut I don't rightly remember... too long ago.
So although it couldn't display a pretty backdrop or a real-time clock it could be set up to display more or less what we use Conky to do now, except on the LogIn screen. (From vague memory, rather than a text string I was redirecting from a file, but that's beside the point.)
Anyways... is it still possible to do this sort of jiggery-pokery on the LogIn and/or Lock Screen? If so, could someone point me at a list of what esc codes are available?
Ummm... come to that, where does Menu>Administration>LogIn Window (cinnamon) actually save the welcome text? It's not where I would expect,
