Linux on the Asus ZenBook UX333

Generally, on any major distro about everything will work. This is with the exception of the hardware screen brightness down button. Screen brightness up will work, but not down. In order to rectify this, the following arguments need to be passed to the kernel at boot:

acpi_osi= acpi_backlight=native

Adding this to /etc/default/grub's GRUB_CMDLINE_LINUX and running grub2-mkconfig should be sufficient to have a working brightness down button on reboot.
