Can you try running g-p-m in debug mode and see if you get any warnings?

        gnome-power-manager --no-daemon --debug

You will probably need to kill the running process first, you could also
try --verbose for extra debugging info.

You can use dbus to access the backlight controls, 

        dbus-send --session --dest=org.gnome.PowerManager
        --type=method_call --print-reply
        --reply-timeout=2000 /org/gnome/PowerManager/Backlight
        org.gnome.PowerManager.Backlight.SetMode string:off

You could also try "standby", and "suspend" instead of "off".
