    sony vaio cw brightness issues


    I am having problems with the brightness control on my sony vaio laptop, at first when i upgraded the driver for the VGA card the whole screen went blank, I had to port a bin file from windows and write my own EDID file to get it to work (nVidia GT 230M), but I am having problems with the brightness, although ubuntu does read the input from the keys (FN+...) (which it stopped doing lately for some reason), the brightness refuses to change, adding the brightness applet to the taskbar does not work either. I really need to be able to change my brightness because the battery usage is off the charts. I appreciate any help I can get with this. I am using Ubuntu 9.10 - Karmic Koala. I have looked up previous posts about this and found one that contained no answer.

    Thank you,
