--- Comment #8 from Aaron Lu <aaron.lu at intel.com> ---
The ACPI dump shows that firmware doesn't provide a video output device that is
capable of backlight control, so no chance for ACPI to create a backlight
interface. The best bet would be the GPU driver to create a native interface,
especially the firmware claims support of windows 8/8.1. Re-assign to GPU/i915.
