I got it on my new laptop Sony VGN-NR38S, after looking all over the internet for info, i came across with this tread here, so for me and for now you have to run this on terminal.Using Ubuntu 9.04 in this laptop.
First make sure that you have this installed in your system,
SmartDimmer

or type in terminal: smartdimmer
if installed in terminal, you will see this

on synaptic you will see this

if not installed then in synaptic right click mark for install and apply,
in terminal:

sudo apt-get install smartdimmer

you can copy and past it in terminal.
Using the terminal to decrease brightness,
open terminal if is closed and type: smartdimmer
this command will bring options like this

  if you type: smartdimmer -g
will show the level of the brigtness

typping: smartdimmer -s 75
this will increase or decrease brigtness

the command: smartdimmer -i
will increase 1level and
the command: smartdimmer -d
will decrease 1livel

this can be done in one go
