Brightness in Dell Vostro 3300 - Ubuntu 12.04

Asked by Leandro Marino on 2012-05-14

Hi,

I've installed Ubuntu 12.04 in my Dell Vostro 3300! I did an clean installation. When I was with Ubuntu 10.04 everything worked fine now, with Ubuntu 12.04 LTS but when I try to change the brightness in the pannel or with the shortcut FN + Down arrow appears the popup indicating that i've changed the brightness but nothing is changed.
