My laptop was locked (showing lightdm unlock screen), and the battery went off overnight.

When I charged it up again there is the lightdm or gnome window asking me the session-end question "user, you have open files..." with the buttons to lock, sleep, restart, shutdown, and a close button on the top. It looks like this, but without mouse over highlights, and with my user unlock UI on the back. Also the top message says

User, you have open files you might want to save. Would you like to..." 

But I cannot click anywhere so I cannot get out of it. I tried going to the console, but the lightdm main process probably owns the window. I can't kill that one or i will lose the session. Anything I can do to fix this?


I killed a process owned by my user /usr/lib/unity/unity-panel-service --lockscreen-mode I was then able to click the password field behind that screen, type unlock and then close that window.
