This looks more like a gnome-power-manager aspect. When you log in as a user (and I suspect the login screen counts as a user) it restores the last configured brightness settings.

If you have more information that pinpoints this bug to X rather than gpm, please feel free to elaborate and reassign it back.

Please have a look at to know how to install that version.Thanks in advance and sorry for the late response.
