I've started writing some code to implement automatic multiseat support in LightDM [1], largely based on GDM implementation of the feature. After several tries, I've got this state, which is a little bit well written, but still incomplete.
I'll really like your feedback about this branch. At the moment, I can list the following issues: * Some login1-related code was introduced, and login1.h was #included, in lightdm.c itself. Is this OK? Should this code be moved elsewhere? * We need to implement properly the functions add_login1_seat() and remove_login1_seat() declared in lightdm.c. * When loading initial seat list from logind (by calling login1_sync_seats()), we always get at least seat0, which may conflict with LightDM property "start-default-seat", so we may end up with two seat0 seats registered in LightDM (one triggered by start-default-seat, and another triggered by login1_sync_seats()). Which is the preferred way to prevent this conflict? * Currently, callback functions for logind signals SeatNew() and SeatRemoved() should be implemented outside login1.c.

I have absolutely no experience with D-Bus interfaces, but it seems that LightDM has its own D-Bus interface for seat management, so I don't know what would be better: replace it with logind D-Bus interface (if logind is present) or chaining both (e.g.: a logind's SeatNew D-Bus signal should trigger LightDM's SeatAdded D-Bus signal). Does it make sense?
