I have a problem with my brightness setting. When I decrease brightness to 1 and I reboot the computer, it reset to maximum brightness value. I tired to adjust it and decrease it again to 1. Why the setting doesn't save the last brightness setting for me? How can I save the current value and restore it after reboot via programming?
I also tried to add
echo 0 > /sys/class/backlight/intel_backlight/brightness in
/etc/rc.local file, but after rebooting, it reset to the maximum again.
