Bug description:
  [Impact]
  Running non X server setups (e.g. Unity 8) and having display server scripts configured leads to LightDM crashing. This is due to a faulty assumption in LightDM assuming all display servers are X servers. Commonly caused by having nVidia prime support installed. Error reports in [1].

  [Test Case]
  1. Install the Unity 8 desktop preview
  2. Configure a display setup script in the LightDM configuration:
   [SeatDefaults]
   display-setup-script=...
  3. Start LightDM
  4. Log in Unity 8
  Expected result:
  Setup script is run and you are logged into Unity 8
  Observed result:
  LightDM crashes

  [Regression Potential]
  Low, fix is simple. Tested with regression tests.
