Now with more El Capitan, and a change of screen layout. Apple seems to be deliberately mocking me!
I have a laptop running Yosemite El Capitan with an external monitor sitting above next to the laptops display. When I am logged in I have the display arrangement mimicking the physical above and below side by side layout. This works and is good.
However when I am logged out the Yosemite El Capitan login screen reverts to an side by side above and below arrangement.
I would like Yosemite El Capitan to keep the side by side arrangement even when I am logged out, but the display arrangement in the System Preferences is per logged in account.
So what would I do to set the arrangement when there is no logged in account?
