You have been subscribed to a public bug: It appears that there are some power management issues related to the new lock screen in 14.04...
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.
