Problem with 100 % brightness after reboot
Laptop does not remember brightness, after rebooting it sets brightness to 100%

Workaround

 * Install acpid and xbacklight


 * Create and copy scripts which save and restore actual brigthness

/etc/acpi/actions/backlight.sh                                                                                                             brightness=`cat /sys/class/backlight/acpi_video0/actual_brightness` brightness_max=`cat /sys/class/backlight/acpi_video0/max_brightness` brightness_out=$(((100000/brightness_max*brightness+500)/1000)) echo $brightness_out > /etc/backlight
 * 1) !/bin/sh
 * 2) It saves actual backlight percentage to /etc/backlight

/etc/acpi/events/backlight event=video/brightness* action=/etc/acpi/actions/backlight.sh %e After backlight.sh and backlight created it needs to apply it with

This script need to be added to startup, for example /bin/sh /home/user/Scripts/brightness.sh, run it as user brightness=`cat /etc/backlight` xbacklight -set $brightness
 * 1) !/bin/sh
