Public bug reported: I'm using a System76 Pangolin. I recently upgraded from 13.04 to 13.10 and thereafter to 14.04. Since I've upgraded, the lock screen no longer works, either through the power menu in the top right corner or using the keyboard shortcut. When I try, a very low opacity overlay of my wallpaper appears on the screen for a second and disappears. All other Unity functions (Dash, HUD, etc) seem to be working.
Let me know if additional information is required.
