Through countless hours of searching, I've compiled two different
scripts into one short bash.
#!/bin/bash
# backlight control (sudo apt-get install xbacklight)
# props to everyone in the ubuntu community ~shyce
xrandr --output LVDS --set BACKLIGHT_CONTROL native
sudo /etc/init.d/acpid restart
app=`which xbacklight`
current=`$app -get`
ans=$(zenity --scale --text "Set LCD brightness 0-100" --value
"${current%%.*}");
$app -set $ans
Enjoy! Something was noted about xrandr not being needed anymore - which
would comment out the first two line, is this true? If so, would you
mind sharing exactly what needs to be done to update our xrandr?
