[Weinga-Unity <snaky.1@xxxxxx>]

As discribed in my first post xev reports repeat key, showkey nothing is repeated.
So which source files of xservers are involved and use the same functions of showkey and will create the xevents?

Im interessted in reviewing the code and (if possible) to add debug
informations.

  showkey does not print anyyyyy scancodes:

  ~$ sudo showkey -s
  KB-Modus war ?UNBEKANNT?
  [ Wenn Sie das unter X probieren, muss es nicht funktionieren,
    da der X Server ebenfalls von /dev/console liest. ]

  Drücken Sie eine Taste (Programmende 10 s nach dem letzten Tastendruck)...
