Title:
  Laptop suspends immediately after startup

Status in systemd package in Ubuntu:
  New

Bug description:
  When booting my laptop while docked with the lid down (pair of
  external monitors attached to dock), the system boots to the point of
  displaying the login dialog, but immediately suspends.  When resumed
  from suspend by briefly pressing the power button, lightdm displays a
  login screen that just prompts for 'password' (no username).  This is
  under xubuntu.

  Intuitively it seems that the system implements a default power
  manager policy, which suspends when the laptop lid is down, before
  having the chance to implement my policy which prohibits this when on
  mains power.

  This behaviour is new in 15.04, on 14.10 and earlier it worked as
  expected - at least gave me a chance to log in.

  There's an easy workaround: boot with the lid up (at least my dock
  permits this - I know of some that wouldn't), but it's annoying.

  Not sure what packages this is - lightdm is certainly running, but is
  this the culprit ?  I doubt xfce4-power-manager has had a chance to
  start ?  Is there a power management service in systemd  that runs on
  boot ?
