[Bug 1270579] Re: On laptops, screen brightness and keyboard backlight isn't memorized between sessions


Not fixed in 15.04. G75VW keyboard backlight and screen brightness
settings are not saved. Also, the screen flashes like hell when trying
to change the brightness using the 'Fn' keys.

Bug description:
    1. Boot a laptop.
    2. Set a different screen (or keyboard) backlight brightness level.
    3. Reboot.

    Backlight is not memorized.

    A. For Ubuntu 12.04 LTS and 14.04 LTS install my package from PPA
      sudo add-apt-repository ppa:nrbrtx/sysvinit-backlight
      sudo apt-get update
      sudo apt-get install sysvinit-backlight

      1. If you have installed previous non-deb version, please remove it carefully manually
        sudo rm /etc/rc?.d/?25backlight /etc/init.d/brightness /etc/rc?.d/?25brightness
      2. If you have installed previous version from my PPA on Ubuntu 14.04, please reinstall the package by:
        sudo apt-get purge sysvinit-backlight
        sudo apt-get install sysvinit-backlight
      3. Version 0.1ubuntu1 supports save/restore of keyboard backlight too.

    B. Ubuntu 14.10 is near EOL (really in July 2015), so users should upgrade it to Ubuntu 15.04 (see C below).
       My script seems to be incompatible with this Ubuntu version - remove it with
        sudo apt-get purge sysvinit-backlight
        sudo add-apt-repository -r ppa:nrbrtx/sysvinit-backlight

    C. Ubuntu 15.04 has systemd-backlight@.service. It saves and restores screen and keyboard backlight levels.
       My script is incompatible with this Ubuntu version.
