After a few rounds of testing, I think there is different result to run
g-s-d with and without the "--debug" argument.
This is what I do:
kill -9 `pgrep "gnome-settings"`; gnome-settings-daemon --debug
And then press the video switch hotkey or super+p and observe if the
xrandr-plugin is called. There will be log like:
(gnome-settings-daemon:21343): xrandr-plugin-DEBUG: applying
=== Applying Configuration Configuration ===

(gnome-settings-daemon:21343): xrandr-plugin-DEBUG: done handling fn-f7
However when testing without killing the g-s-d process first and without the
--debug argument. The video switch does not work.
This could be a race of grabbing the key or some timing issue as it
seems.
