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.

  • Refreshing the topic: did you get to any conclusion? I am facing the same issue with hp 1040 g5 on both Ubuntu 18.04 and Ubuntu 20.04. What is worst the built in mic doesn't work and I wonder if it is related to not working mic mute key (xev and acpi_listen doesn't show any event for this key) or it is a different issue. – jaz Dec 09 '20 at 12:19
  • There were some bugs opened on launchpad. But not really a satisfying solution...

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.

  • I second that. A power reset on a HP notebook worked for me too. –  Oct 06 '21 at 23:23
  • none of the function buttons were working on my Elitebook G10 after an Ubuntu system update and this fixed it for me – kdarras Feb 09 '24 at 08:18
