Have you ever tried this under Windows? All brightness up/down and micmute reports the same scancode.
Let's assume it's not a hardware defect, it probably needs special WMI hotkey driver to generate brightness hotkey events. Please raise the issue to the vendor. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1852071 Title: [HP ZBook Studio G5, Ubuntu 18.04.3 LTS] Brightness function keys works as microphone mute function keys To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1852071/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
