Sounds like a video driver issue. ** Package changed: lightdm (Ubuntu) => xorg-server (Ubuntu)

When lightdm comes up, I see the mouse cursor, it disappears and then I cannot move the mouse. The system, however, is still responsive, I can press the power button to see the Unity shutdown menu and the mouse cursor on the default user session still animates. I however cannot tty down and cannot do anything other than force shutdown. Attached are the contents of lightdm.log.old on the next boot. This hasn't occured for me on 14.04.1 nor Freya. It started happening when I installed 15.04 and then 14.04.3 so I believe it's related to the 3.19 hardware stack or lightdm 1.10.5. I have a mostly intel system, a Lenovo u410. I'd prefer to fix the issue rather than avoid it since I cannot download 14.04.1 anymore. During the expected behavior, lightdm boots, the mouse dissappears and then reappears (why it's mounting and unmounting when plymouth closes is beyond me). And I should be able to use my mouse/kb when resuming or cold booting.
