Public bug reported: What happens:
1. I lock my session 2. Time passes; screen goes blank 3. I type in my password 4. I get my session back for 2 seconds 5. Screen blanks (given enough seconds, the monitor says "no HDMI input") 6. I move the mouse, the screen comes back 7. I get another password prompt (same as the one in step 3) 8. I unlock the session correctly 9. I resume work. What should happen instead are steps 1-3,8-9.
