Instructions for getting backlight working on UX301LAA ultrabook
View Instructions
Core problem:
Fn buttons are controlled via ACPI. ACPI is configured via a board specific firmware called the DSDT. The DSDT sections for backlight broken for UX301LAA, so it needs fixing. I have attached my DSDT file which work on my machine (I have not tested it extensively, but backlight works at least).
#1 Dump the current DSDT to a file:
cat /sys/firmware/acpi/tables/DSDT > dsdt
#2 The DSDT is compiled, so we need to decompile it
iadsl -d dsdt
#3 Often, the file is not properly decompiled, so re-compile it in order to discover any de-compilation errors. Fix any errors (the code is probably unparsable if there are errors, so you need to guess the correct semantics).
