I'm using Kubuntu 12.04 LTS.
I'd like to know where I can put the script of mine described below to run immediately after the splash screen of the initialization begins.
#!/bin/sh
contrast=`echo "scale=2;6/10.0" | bc`
brightness=`echo "scale=2;40/1.0" |bc`
xgamma -quiet -gamma $contrast
xbacklight -set $brightness
PS.: This script (for while) changes the brightness and the contrast of my screen. I would like to improve it to perform other things but first I need to know how can I solve the problem described above.
