This bug was "fixed" by re-installing Ubuntu 16.04.3 (downloaded from ubuntu.com a few days ago).
The buttons did not work initially when I installed the original 16.04 LTS version released in April 2016, so I'm guessing that version of the kernel did not have that fix. The current version of the kernel used in 16.04.3 fixed this issue. So the bug should probably be with the upgrade mechanism of the kernel.

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.
