I've noticed that, "localectl" was no longer reporting my preferred X11
keyboard model - should be:

 # localectl 
System Locale: LANG=de_DE.UTF-8
    VC Keymap: de
   X11 Layout: de
    X11 Model: cymotionlinux
  X11 Variant: de_nodeadkeys
  X11 Options: terminate:ctrl_alt_bksp
 # 

Was:

 # localectl 
System Locale: LANG=de_DE.UTF-8
    VC Keymap: de-nodeadkeys
   X11 Layout: de
    X11 Model: microsoftpro
  X11 Variant: nodeadkeys
  X11 Options: terminate:ctrl_alt_bksp
 #
