Class equipment for a Kodi-Media Center

I use the remote control for a media center on Kubuntu / KDE 5.3 / Kodi basis *. Within Kodi mouse functionality is disabled, but on the desktop control is accurate enough for casual surfing. The window-closing-X is encountered FullHD with a little practice, but that's rather the limit of accuracy.
Power, + Control Pad, Play / Pause, Fast Forward and Rewind and the Back button operate out-of-the-box and do with it Kodi absolutely controllable. The Keymap plugin (or with the config XML) can be also confirmed by the other keys: Home, for example, for the home screen, Menu for the context menu.
The "Game" button "is recognized under KDE as F6 and serves with me to switch between workspaces. Kodi is on worktop 1 ,, working surface 2 is normal desktop. Switch works perfectly even during video playback.
STB and TV as I have keys for infrared occupancy freely, AI Power I could not prove.

Infrared work with my projector, but not with my (fairly old) Technics stereo. For this and for the design, which feels a bit as if the remote control still in an envelope, a star deduction.
