I've no idea why ACPI brightness control method doesn't work.
Please add acpi_backlight=vendor to kernel cmdline, see if there is only one interface(intel_backlight) left under /sys/class/backlight. If so, I can add your system into a blacklist table.

BTW, is there a firmware update for your laptop from ASUS?
