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... Good luck,
