Enabling Volume Control Buttons on HP TouchSmart Desktop Computer 600-1350 with OpenSUSE Leap 42.1

I have a Hewlett Packard TouchSmart Model 600-1350 Desktop computer, which is Intel Core 2 Duo based running at 2.0GHz with 4GB of RAM, 512GB Hard Disk and Nvidia GeForce 98M [9300 GS] GPU. This system originally came with Windows Vista installed on it and I successfully installed OpenSUSE Leap 42.1 with KDE Platform Version 4.14.18 on this without many problems. However, I would like to know if anyone has come up with a way to make the hardware buttons on the right side of the computer for volume control and mute to work with the KDE desktop Audio Volume? Also, the small round button on the front lower right corner, which has the House symbol on it, has anyone made it functional in KDE?

Thank you,

David A. Smith

I can only write a general reply here. With luck, someone might be able to reply more specifically/completely. It will depend on how these special keys are handled. Some hardware keys/buttons generate ACPI/WMI events and require support via a hardware-specific WMI kernel driver (eg hp-wmi.) Others might generate keyboard scancodes. For the latter, you could test by installing ‘xev’ and run the utility of the same name. Check if pressing these buttons then generate any keyboard event.
