I'm running C++/QML applications compiled with Qt5.7.0 for RPi3 (Raspbian Jessie Lite) without X (eglfs).
All work fine but when the applications start the keyboard is disabled. I do not need it for the application itself (i.e. there is nothing to edit!) but I can't stop it, nor change tty.
No key is working anymore, even the bloc num/caps led.
I must cycle power to gain again the prompt!
I didn't recall such a behavior with Qt5.6.x. Is there something I need to do? I.e. some env vars to export?
