Human ships the following brightness related icons:
notification-display-brightness-full notification-display-brightness-high notification-display-brightness-low notification-display-brightness-medium notification-display-brightness-off
Whereas notify-osd only ships a single icon:
notification-display-brightness.
I suspect that is probably the issue, although I don't have a laptop with brightness keys to test. Mike - perhaps you could create some symlinks in /usr/share/notify-osd just to verify that?
