Display needs to be unlocked twice

[Jussi Lind]

I've had this issue since the new lock screen:

1) Wait for the display to get locked
2) Unlock the display by entering you password

What should happen:
- The display should unlock and stay unlocked

What happens instead:
- The display gets unlocked, but after ~15 secs the display gets locked again by itself
- Unlocking the display once more makes it now stay unlocked

This happens something like 7/10.
