Dear armbian experts   For a kiosk-like system with a touch screen only, I need a virtual keyboard that pops up on demand and hides again when not needed.   I have installed successfully the onboard keyboard package, see https://launchpad.net/onboard.   The software has all the desired features and works fine so far. Only auto show / hide does not work, i. e. something seems to be wrong with the communication between onboard and other applications like Firefox etc.
