patch: suspend on close lid even when external display is connected

I've configured my laptop to suspend when the lid is closed (in gnome-control-center's Power panel). It works ok as long as there is no external display connected. However when I connect my external LCD, laptop IS NOT suspended (external display is turned off though).

I'm experiencing this in Unity on Ubuntu 12.04 (see related bug report there [1]). However from code it seems that this issue affects Gnome too.

I've done some research and found out that problem is in gnome-settings-daemon package: There is code in gsd-power-manager.c in do_lid_closed_action function which checks whether there are any active external outputs and if it finds any, it prevents suspending. I believe that in this case we should honor what's set in gnome-control-center and suspend. Patch which removes this logic is attached.
