Hi Jarkko, Thank you very much for your response! I did the procedure you described and it solved the problem! Brightness function keys started working properly in Ubuntu. I repeated this procedure on other ZBook Studio G5 laptops we have here and it also did the job. However! I have dual boot - after logging into Windows 10 (where buttons always work perfectly fine) and then logging again into Ubuntu brightness keys stopped working again (they were recognized as Microphone key, again). I had to do the Power Reset procedure once more which fixed the issue in Ubuntu. After testing multiple restarts Ubuntu -> Ubuntu: brightness function keys are always working fine. After just one Ubuntu -> Windows -> Ubuntu restart: brightness function keys stop working in Ubuntu (but work fine in Windows).
So each time after I used Windows I must do the Power Reset procedure if I want to have brightness function keys working in Ubuntu. -- 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
