That's my script 'lumino' :
#!/bin/bash
file=$HOME/lumino
med=40
if [ -f $file ]
then
l=$(cat $file)
else
echo $med > $file
l=$med
fi
case "$1" in
"+")
l=$(( $l + 5 ))
[ $l -gt 95 ] && l=95
;;
"-")
l=$(( $l - 5 ))
[ $l -lt 5 ] && l=5
;;
esac
echo $l
sudo setpci -s 00:02.1 F4.B=$l
echo $l > $file
Before to execute it, modify the /etc/sudoers file with sudo visudo and add (or
modify) this line :
user user-samsung140 = NOPASSWD: /usr/bin/setpci
Use the good name user and the good machine name.
This is for don't request the password for root.
I will try the solution of Fortunato.
