Apparently the Fn+"UpArrow-Brightness"  is supposed to run this script:

/*/etc/acpi/video_brightnessup.sh*/
 
and the down button  should run
 
/*/etc/acpi/video_brightnessdown.sh*/

/I found this out accidentally by running Method 3 as shown on
https://wiki.ubuntu.com/LaptopTestingTeam/HotkeyResearch

After I exited from running Method 3,   Fn+Up or Fn+Down now control lcd 
brightness as they should. You see a small window with a bar indicating 
the LCD brightness with each press of the Fn Up/Down.  I'm guessing that 
once I reboot,  I'll lose that functionality.

Also there is supposed to be a gnome applet that controls LCD 
brightness.   I looked in the available packages for it but didn't see 
it.    I'm using KDE and so far I haven't found a corresponding applet.
