Keyboard Mappings for 14,3 non US non-iso keyboard

[marc-git]

I am using a German 14,3 and since libinput manages keyboard settings I am struggling to set the keyboard to non-iso so that for keys like @ I type Alt+L (where the @ sign is) and not Alt+Q. I think there was some simple flag to indicate that it is a non-iso keyboard. Anybody know how to do that ? I think it applies to all non-us apple keyboards on all distributions, certainly on debian.

I am also quite sure there used to be a setting to disable the touchpad while typing, but can't locate that since reinstalling. Anyone now?
