Please describe the problem:
Once gnome-screensaver and gnome-power-manager runs *one* succesfull cycle of
1. activating the screensaver (e.g. showing some photos from f-spot)
2. turning the screen off (backlight off)
3. going back to normal work -> deactivating screensaver
4. activating screensaver again on inactivity
5. screen *never* switches of again. the inactivity timer doesn't works for backlight off in gnome-power-manager

I would reccomend to unite gnome-screensaver and gnome-power-manager to one project since they are sharing so many goals. At least implementing a "backlight off" in the screen blanking saver would be an elegant solution for this. What is a simple screen blanking good for in the age of LCDs?
