Bug Description

Noticed after disconnecting external monitor today that the Fn-Left and Fn-Right keys, which normally
1) Trigger the display of a sun icon with a progress bar of the amount of supposed brightness the screen is supposed to have
2) actually changes the amount of brightness that the screen is supposed to have

currently only does (1) (ie not (2)).
