Bug#524344: gnome-power-manager: adjusting brightness kills AltGr key behaviour

KIRBY MISPERTON (n.)
One who kindly attempts to wipe an apparent kirby (q.v.) off another's
face with a napkin, and then discovers it to be a wart or other
permanent fixture, is said to have committed a 'kirby misperton'.
