Comment 5 for bug 1393767

> You could argue that the DPMS settings conflict and that this one should be removed though.

dpms don't conflict, because they are synced between xfpm and light-locker-settings.

> Since no service handles the blank times with the switch away from XScreensaver to light-locker, we decided that light-locker-settings should take care of it until xfce4-power-manager was ready.

Here lies the problem: Since xfpm does not handle screen blank, one can easily break the power source dependent monitor pm of xfpm. Consider following situation: User sets up ac timings in xfpm to 10/15 and battery timings to 7/10. While on battery he decides to reduce this timings and uses light-locker-settings to set them to 3/4. Back on ac he wonders why his screen goes black after 3 min. He checks light-locker-settings and xfpm and both say 10/15.
xset q shows, that xfpm did switch the timings after the power source has changed, but since it does not handle screen blanking it is still set to 3.

I guess the question here is, do we want (incomplete) screen blank gui support for crt monitor users (afaik on lcd monitors screen blank, dpms standby/suspend/off are all the same), or a consistent monitor pm with xfpm.
