You have been subscribed to a public bug:

Brightness control key is broken on UX302LG laptop.

Other hotkeys work (as per Bug #1270661) .

Soft control works and is able to dim screen brightness.

- Key does not output anything using xev.
- Nothing shows up using acpi_listen when pressing the key.

Tried acpi_type=vendor with no luck.

>From discussions I had, next step would probably be to dump DSDT from
/proc and try to recompile them with the Intel ASL compiler that could
indicate where problem lies, fix the error and use that specific blob at
boot time.

** Affects: linux (Ubuntu)
     Importance: Undecided
         Status: Incomplete
