Hi Marcin, Try to perform a power reset: https://support.hp.com/ph-en/document/c01684768 That is: turn the computer off, remove all cables, press and hold down the power button for 15 seconds. Turn the computer on and reconnect the cables. The brightness buttons should start working.
Worked for me with the exactly same computer with Ubuntu 19.10. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in 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 Status in linux package in Ubuntu: Confirmed Bug description: 1.
