Setting Brightness right on Ubuntu
Well, i accept it. I tried everything available on Google and nothing seems to work for me to control my Lenovo laptop's screen's brightness. So i wrote a little script to get my work done. .setbright.sh: #!/bin/sh if [ $# -ne 1 ] then echo "Usage: bright 50" exit fi x=$((($1*254)/100)) n=$(echo "ibase=10;obase=16;$x" | bc) sudo setpci -s 00:02.0 F4.B="$n" #End of setbright.sh Then modfied my .bashrc as: alias bright=$HOME/.setbright.sh bright 50 #Set Brightness to 50% Now use on command line as: bright 60 Am happy as of now with this!!
