[SOLVED] HP ZBook Power G9, Keyboard issues on Linux

I have several issues with the keyboard on a HP ZBook Power G9 and no idea how to solve that:

When NUM pad is enabled, the arrow keys are not working anymore, up down left right are all sending display DIM low.

fn+F8 for Mic mute does not work.

I can't use the Print Screen button for screenshots. Applying a button for screenshots in Xfce, I press the Print button and it's detected as Print button. But when using it, it is only lowering the display brightness and not starting a screenshot. The shortcut for CTRL+Print works.

Recently Backspace stopped working by some misconfiguration and I can't figure out why: [1]

All solved after removing i8042.* from CMDLINE as mentioned in [1], not sure what they were required for in the past...
