Code review comment for lp:~albaguirre/unity8/use-new-display-power-state-interface

* Are there any related MPs required for this MP to build/function as expected? Please list.
Yes there are:

https://code.launchpad.net/~albaguirre/unity-system-compositor/screen-power-state-handling/+merge/213957

https://code.launchpad.net/~albaguirre/powerd/remove-input-inactivity-handling/+merge/219449

 * Did you perform an exploratory manual test run of your code change and any related functionality?
Yes. I tested that the greeter is still shown when powering on/off the screen through the power key and that the greeter is not shown when screen is turned off due to proximity events.

 * Did you make sure that your branch does not contain spurious tags?
Yes

 * If you changed the packaging (debian), did you subscribe the ubuntu-unity team to this MP?
N/A

 * If you changed the UI, has there been a design review?
N/A
