I installed Ubuntu 18.10 on my HP EliteBook x360 1030 G3 and can't get all fn-combinations to work.

What works: Volume up/down, Mute, Airplane mode What not works: Brightness up/down, Microphone mute

The often stated kernel parameters as listed here aren't resolving this issue.

Trying the command showkey -k revealed some strange behaviour: For all combinations not working a press and release with the same keycode (465) is generated. The other combinations result in different codes.

When running xev or acpi_listen no event is listed for the malfunctioning combinations.

Would be great if there is a way to get any reaction for this key combinations.

A power reset worked for me! It fixed all hotkeys troubles, AND also a problem with no speaker sound after plugging and unplugging headphones. Running Ubuntu 20.10, see

---> press and hold the Power button for 15 seconds to reset. then all hotkeys were fine.
