It’s been 2 years that I bought my current laptop: a Asus UX32LA. After a year on Windows, I decided to pass it on Linux. I’m currently using Arch Linux but I had a screen backlight fn keys issue with others distributions too (mainly Ubuntu and Fedora). The fix is very simple but not straightforward to find. You just have to put acpi_osi= in your kernel boot option.

This option disables all strings from the acpi_osi arguments. This arguments changes the list of supported OS interfaces for the BIOS. I hope this help!
