I have the same issue on Xubuntu 16.04.1. A workaround for me is to hit
Ctrl-Alt-F1 to bring up a tty, login, and run 'sudo service lightdm
restart'.
This kills my session, which is annoying, but is faster than a reboot.

In the previous LTS version (14.04) this issue didn't occur.
I switched to Ubuntu GNOME because of this issue, the unlock screen works

problem.
