Description David Strobach 2016-10-31 21:53:25 UTC 
Since the org.kde.KWin.InputDevice interface is exposed on D-Bus it is possible to alter the input device configuration. The configuration gets however reset back to defaults once the user switches virtual terminals.
Comment 1 Martin Flöser 2016-11-01 07:10:57 UTC 
Not completely unsurprising: when switching vts we lose all input devices. On gaining vt we get the device recreated.
Comment 2 Martin Flöser 2016-11-03 10:47:06 UTC 
My suggestion is that we start to store configuration when a device gets configured. When a new device is added, we check the configuration and restore the settings as in the config.

This would make the changes not only persistent when doing a VT switch, but also in general (system restarts).

Implementation for the idea outlined in comment #2 at https://phabricator.kde.org/D3264
