Logitech Presenter R400 in Linux Mint

In general the Presenter R400 works fine, it’s immediately active after the USB receiver is plugged in and the keys representing Page Up/Down are working out of the box. Thus presentations in LibreOffice/OpenOffice, PDF Viewer (in my case Okular) and Google Docs are stepping forward and backwards using the main keys.

In contrast the smaller keys for jumping to presentation mode and disabling the display are sending codes, that the KDE desktop can’t process.
