I have this issue with the proprietary Nvidia graphic drivers (Nvidia-331-updates). I upgraded from 13.10 to 14.04. I did not have this issue in 13.10 with the old lock screen. If any other information is required, please let me know.

To me, it appears that the screen never goes to sleep while displaying the lock screen, yet when I unlock it the screen often immediately goes to sleep and is then woken back up because I'm now using it.
