    1. Brightness control
    /etc/default/grub

    then change

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    GRUB_CMDLINE_LINUX=""

    to

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"
    GRUB_CMDLINE_LINUX="acpi_osi=Linux"


    To default set the brightness control at boot
    gksudo gedit /etc/rc.local

    #!/bin/sh -e
    #
    # rc.local
    #
    # This script is executed at the end of each multiuser runlevel.
    # Make sure that the script will "exit 0" on success or any other
    # value on error.
    #
    # In order to enable or disable this script just change the execution
    # bits.
    #
    # By default this script does nothing.
    echo 85 > /sys/class/backlight/intel_backlight/brightness
    exit 0

    Replace 85 with your requirement of brightness level
