sudo /etc/init.d/acpid restart
sudo /etc/init.d/hal restart
And Fn+F5 and Fn+F6 works, only fail that don't show the correct % in graph.
I think that graphical % fails because:
/usr/lib/hal/scripts/linux/hal-system-lcd-set-brightness-linux
and
/usr/lib/hal/scripts/linux/hal-system-lcd-get-brightness-linux
aren't working correctly. Only this fault.
