In the testing for this thread, I mostly fully signed off one account
and fully logged in to the other rather than using "su". For renaming
and "ls" kinds of things, I did use "su". But for viewing,
screen-capturing, and the localectl and locale commands, I wasn't sure,
so I did the full logout and login.
(the question)
For what is "su" good enough, and for what is the full logout and
login needed? A full detailed list is impractical, but could someone
provide some good guiding principles?
It depends solely on what needs initialising.
An su will produce a new shell with the latest environment settings. So
you can test terminal level locale changes etc. If you _invoke_ a new
GUI programme from that shell, it should inherit this stuff too.
A GUI logout/login will initialise the desktop, which tends to happen
before any terminal shell. So if you're fiddling GUI stuff and _not_
invoking programmes from a shell, the thing you've invoking them from
needs to see the changes. For a GUI, that tends to mean restarting the
desktop (since you invoke GUI programmes from desktop
buttons/icons/menus usually). And a logout/login restarts the desktop.
