How to run python script at login screen?

  • 772

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?

python

  1. I'm not 100% sure of this, but i recall that i have used /etc/rc.local in similar situations. add a line that executes your script there.

    And then there is upstart that might work. But i have no experience with that except a script that i found to autostart deluged

    Your startup script would probably look something like

    start on startup

script
  python - <<END
    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)

  END
end script
