First, open terminal by pressing Ctrl+Alt+T and execute following command:

gksudo gedit /etc/default/grub

Navigate to 11th line, there will be GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" line. Add acpi_backlight=vendor next to quite splash so the line would be:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

Save the file, then run update-grub command to apply change you have made:

sudo update-grub

Finally, restart your system

You can't say "11th line" for example I've added 10 comments at the start of my grub – WinEunuuchs2Unix Nov 21 '16 at 05:29
also, whether this will work or not depends on hardware – Zanna Nov 21 '16 at 07:47
