For Rebellious Screen Backlights

I had a problem on every Linux distro I ever used on this specific laptop. The light setting wouldn't change, no matter how much I pressed on the designated buttons.

On the #korora IRC channel, I got this very good tip from csmart I thought I should share:

As an administrator, open /etc/default/grub, and then locate the line that starts with GRUB_CMDLINE_LINUX. On that line, inside the quotes, add "acpi_osi=Linux acpi_backlight=vendor" (no quotes) and then you need to refresh your grub information and finally reboot.

You can get more information on the Arch Wiki.
