When I replug in Ergodox to PC, it shows always "de" layout.
setxkbmap -query
% setxkbmap -query rules: evdev model: pc105
work-around is call setxkbmap -layout use. That's a bit annoying.
The right solution is giving the right one via udev. https://askubuntu.com/questions/337411/how-to-permanently-assign-a-different-keyboard-layout-to-a-usb-keyboard
