Comment 7 for bug 1393767

Just to be sure there is no misunderstanding, I was talking about light-locker-settings 1.2.1 and xfpm 1.2.0 (both from trusty). The patch is for those versions. If you decide to apply it, we will loose a gui to set screen blanking (it will be turned off), but we will gain better consistency with xfpm and eliminate some confusing configuration results.
