Public bug reported:

I am unable to unlock my computer using LightDM.
When I enter my password and press unlock, the screen goes black, as if I just relocked the computer, then returns to the same unlock screen after I press any key.

The workaround I found is to hit click "Switch Users", and login through
that path.
