Bug#684331: gnome-settings-daemon: Media-key to switch to external monitor doesn't work

Package: gnome-settings-daemon
Version: 3.4.2-4+b1
Severity: normal

Dear Maintainer,

I have a hotkey/multimedia key/action key (Fn+F4) on my notebook's keyboard to
switch to external monitors/projectors etc. I thought it would be a normal
XF86Display-key so what I expected was something like this:
https://live.gnome.org/RandR#Handling_of_the_XF86Display_hotkey

While trying to define a custom keybinding I realized that this action key is
mapped to Super+P. In the meantime I read some bug reports like
https://bugzilla.gnome.org/show_bug.cgi?id=651571 with users complaining that
Super+P is a hardcoded shortcut (VIDEO_OUT_KEY) but shouldn't be. In dconf
editor I can see that in "org.gnome.settings-daemon.plugins.media-keys" "video-
out" is set to "<Super>p".

So from what I read my 'switch to external monitor'-key should just work –
but it doesn't…

Regards,
Stefan.
