Backlight control does not work after updates (16.04)

by Mathieu   Last Updated July 17, 2017 10:02 AM

After updating my software on my computer, I can't change the brightness, either through the Fn keys or by going in System Settings --> Brightness & Lock. While backlight control does not work at all, there are entries in /sys/class/backlight. The few fixes suggested here having to do with ACPI give no results.

If I try to use Fn keys to change the brightness, I still get the indicator showing brightness changes -- but there isn't actually any change in brightness.

I'm on a UX305C Asus laptop with Ubuntu 16.04 LTS.
