Comment 13 Dan Callaghan 2015-08-18 03:25:44 EDT
Oh I just had a peek at the set_session function which was crashing. I think this is because I haven't got any valid X sessions installed on this system yet (still just trying to get X working with this graphics card).

It would be nice if lightdm could handle that situation sanely -- at least starting up and showing a login prompt or error message, even if it won't let me actually log in.
