Keyboard layout

TODO

Apparently, evdev is a rule.
xkbcomp compiles XKB keyboard descriptions.
setxkbmap ch
setxkbmap us
setxkbmap us -option 'caps:swapescape' (Compare with /usr/share/X11/xkb/symbols/capslock)
Exporting the keyboard configuration to a file: 
$ xkbcomp -xkb $DISPLAY exported-configuration-file
What does evdev mean/refer to?

Arch linux

/etc/X11/xorg.conf.d/20-keyboard.conf
localectl list-x11-keymap-layouts
localectl list-x11-keymap-models
localectl set-x11-keymap [layout] [model] [variant] [options]
