I use a python script to set brightness to zero.

#!/usr/bin/python

import dbus 
bus = dbus.SessionBus() 
proxy = bus.get_object('org.gnome.SettingsDaemon',
                       '/org/gnome/SettingsDaemon/Power') 
iface = dbus.Interface(proxy,dbus_interface='org.gnome.SettingsDaemon.Power.Screen')
iface.SetPercentage(0)

I've put it in Startup Applications. It works only when I login. There is full brightness at login screen.

Where should I put this so that it sets brightness to zero at login screen?
