Why do I get these messages when I hit this key,
<XF86MonBrightnessDown> is undefined
why can't emacs ignore that like bash does?
Just because I adjust the brightness doesn't make it part of emacs'
business. OK, I suppose I need to add something to .emacs to make that
key and its brother no-ops.
P.S., the messages don't end up in the C-h e buffer.
One has to use C-h k to capture them.

In most setups (Gnome Shell, Unity, etc) the window manager will
intercept the XF86MonBrightnessDown (etc) keys and perform whatever
action you have mapped to those keys, and no windows will actually
receive the event.

So if your Emacs gets the event, something was misconfigured in your
setup, I think.

Having Emacs bind these keys globally to `ignore' wouldn't be a good
thing, I think, so I'm closing this as a "wontfix".
