Backlight

In order to be able to control the backlight, the following changes will need to be applied to /etc/default/grub.

FILE /etc/default/grub

GRUB_CMDLINE_LINUX="acpi_backlight=vendor acpi_osi=Linux"

Then execute grub-mkconfig to apply the changes:

root #grub-mkconfig > /boot/grub/grub.cfg
