Title:
  Screen position and settings lost during KVM switching or Super-P

Status in gnome-shell package in Ubuntu:
  New

Bug description:
  On a machine with multiple (3) monitors, I'm able to setup the order &
  positioning of the displays, and indicate the primary display.

  However, some of the time, if I toggle mode with Super-P key combo,
  returning to the same mode, the display order is lost, the primary
  display setting is lost. Open windows end up on the wrong screen.

  The same behaviour is observed, some of the time, when using a KVM
  switch, switching the displays to a different machine. On switching
  the KVM back to the machine, the display order, positioning and
  primary display settings are lost and have to be reset.

  Sometimes, the display order, positioning and primary display setting
  survive a KVM switch or a super-P mode toggle.

  Gnome-shell/mutter/ubuntu should maintain the display positioning,
  order, and primary display setting.

  In mode setting or KVM switching, there are noticeable delays as the
  monitors re-awaken themselves and communicate their EDID's, geometry,
  and connection topology (daisy-chained DP monitors).
