Ubuntu: F3 and F4 buttons do not change the brightness.

HP Probook 440 G6
Linux

I have recently bought a HP ProBook 440 G6 and the F3 and F4 buttons are not working to alter the brightness. Instead they turn on/off the microphone, just as the F8 button does. How can I properly reassign or fix them. Switching to Windows is out of consideration.
Tried on:

  • Ubuntu 18.04
  • Ubuntu 19.04
  • Pop!_OS 18.04
  • Pop!_OS 19.04

I'm sorry, but we here are not equipped to provide detailed Linux support.

The primary "challenge" to using Linux on any HP PC is the availability of Linux drivers. Any hardware that does not work will then range from simple (if there are Linux drivers available) to impossible (if there are NO Linux drivers available) to fix.

Since HP does not provide Linux drivers, your best bet for Linux support is to contact the support forum for the Linux distro you are using -- in this case, the Ubuntu Forums: http://ubuntuforums.org/
