http://ubuntuforums.org – hi everybody, i have problems with the brightness in xubuntu 12.10, first i have a notebook toshiba satellite sp4216sl with amd graphics and processor amd dual core e300 with 2gb ram. The problem is that i can't change the brightness in the desktop while i work, see videos,play, or other thing, i can change the brightness modifying etc/rc.local but this is uncomfortable because i have to reboot t (Hardware)
