By the way: Could this bug be related to systemd? I could imagine that, because (a) this does not occur on Utopic and (b) I just found someone having problems using an external screen, and those problems are related to systemd (http://askubuntu.com/questions/613693/15-04-closing-lid- does-not-suspend-laptop-if-connected-to-external-monitor).
