Our setup:

1. Older GPU(Integrated Intel® HD Graphics 2000)

2. Always using some sort of display multiplexer(splitter) on VGA out to
dual TV’s, previously, now only single local monitor on VGA and 4K
Tx(wireless) on HDMI out to a projector, currently.

Thoughts:

1. Could the splitter or wireless transmitter be inducing some sort of
delay or interference with the EDID detection of the monitors expected by
gdm3 + gnome-session + mutter in an X11 session?

2. What is slick-greeter doing differently from gdm3 that avoids this
problem?

3. Does LightDM differ from slick-greeter all that much?

Bug description:
  (Noticed on Ubuntu 14.04 beta 1 GNOME)
  At work I have a second screen, which I prefer to virtually put on the left 
side of my laptop screen.
  Using gnome-control-center I can change the position of the second without 
problem.
  But when I disconnect the second screen (to work on another place) and then 
connect it again
  OR if I just power off the laptop and turn it on again,
  the second screen position is set back to the default right position.
