[Bug 933710] Re: Laptops with eDP panels do not suspend when lid closed

[Seth Forshee]

Upon further inquiry I've found out that the ConnectorType property that
gnome_rr_output_is_laptop() just isn't implemented for most of the video
drivers in X, and it isn't likely to be fixed in the near future.

So for precise something along the lines of the patch I've attached is
going to be required. Federico Mena-Quintero commented on the upstream
bug report that the patch makes sense. Is that enough to move forward
with it? This really ought to be fixed for precise, or else the code in
g-s-d that using this function to leave the machine running when the lid
is closed ought to be removed.

  Laptops with eDP panels do not suspend when lid closed

Bug description:
  Recently this machine stopped suspending when the lid is closed. It
  suspends just fine from the menu, but when the lid is closed the
  backlight turns off for a few seconds then comes back on, but the
  machine never suspends. I can't find any indication in the logs that
  anything even attempted to initiate a suspend. Often after opening the
  lid the desktop has become completely unresponsive.

  I'm not sure that this is a bug in gnome-settings-daemon, but I've
  traced it up the stack far enough to know that the events are coming
  out of the kernel and that upower is detecting the lid status changes
  and sending out events on dbus.
