Boot your Linux live CD/DVD

After the installation on the hard drive the computer should reboot now
  1. In the boot screen of Linux live CD/DVD press Tab and add 
  2. GRUB_CMDLINE_LINUX="acpi_osi=Linux"
  3. Press Enter
  4. When the system loads try press the key shortcut to adjust the screen backlight, in my case <Fn> + <Left/Right Arrow> 
  5. Open the terminal a type sudo gedit /etc/rc.local and add
    setpci -s 00:02.0 F4.B=00;
