Comment 17 for bug 45021

Please also include this script, if anyhow possible:
http://omke.cvs.sourceforge.net/viewvc/*checkout*/omke/omke/omke.pl

It enables switching screen backlight on and off:

# backlight off
sudo ./omke.pl -d 0
...
# backlight on
sudo ./omke.pl -d 1

When combined with a gnome key binding this may replace the otherwise unsupported function key.
