Public bug reported: I have an ASUS UX305C laptop, and some of the function keys do not work.
The keys in question: fn - airplane mode (f2) fn - brightness down (f5) fn - brightness up (f6) I followed the troubleshooting guide at https://wiki.ubuntu.com/Hotkeys/Troubleshooting with the following results: 1. acpi_listen gives no output when those keys are pressed 2. xev gives no output when those keys are pressed The keys work on Windows 10. On a more recent version of the similar laptop UX430UA-DH74, using the same version of Ubuntu 16.04.3, the same keys work properly.
