Public bug reported: Whether it matters or not, I have a rather complicated setup with a Kaby lake Thinkpad, dock station and several displays. When I go to lunch I lock my session. I cannot unlock it once I come back. I enter a valid password and all controls become disabled as if it is checking the password right now. However, the screens remain locked even after minutes of waiting. Ctrl-alt-Fx works and everything else works as well: I can login there and cat syslog. There usually are some recent messages about locking inputs. I can reboot gracefully. I probably can restart the X session (didn't try it). I can come back to the existing X session after a while and try to re-enter password but that fails with exactly the same symptoms as my first attempt.
