Your desktop (Gnome, XFCE, KDE etc) should have a brightness app and
a session manager which, when you log out, knows to signal the apps
to store their relevant settings so that those settings are
re-applied when you next log in.
Another "problem" which can happen - if you set internal laptop LCD
to zero brightness, then suspend, then unsuspend, brightness in some
configs gets set back to 100% - but this is so that user knows to
enter e.g. password to unlock the screen, which might be challenging
if it is set to zero brightness...
