First of all, the xscreensaver should be installed and replace the default gnome-screensaver.
You may follow the instructions from the post :
http://ubuntuforums.org/showthread.php?t=195557
Then, to recover the menu 'System / Lock Screen', the dbus object org.gnome.ScreenSaver should be created.
I use the below python script to create the org.gnome.ScreenSaver.
#!/usr/bin/python import dbus import dbus.service import dbus.glib import gobject import os class ScreenDbusObj(dbus.service.Object): def __init__(self): session_bus = dbus.SessionBus() bus_name=dbus.service.BusName("org.gnome.ScreenSaver",bus=session_bus) dbus.service.Object.__init__(self,bus_name, '/org/gnome/ScreenSaver') @dbus.service.method("org.gnome.ScreenSaver") def Lock(self): os.system( "xscreensaver-command -lock" ) if __name__ == '__main__': object=ScreenDbusObj() gobject.MainLoop().run()
Keep this script running on the background. The 'Lock Screen' button will call the method Lock and the method Lock will execute the xscreensaver-command -lock.
To automatically start this script, add the command,
i.e. /path-to-the-script/myscreen-dbus.py &
in the System/Preferences/Sessions.
