Hello Coderus!

Thank you for your answer!
The problem was not related to the PM, but was related to this package: https://openrepos.net/content/pengui...arian-keyboard

I have installed that in the past, but it had not had any effects (the Hungarian keyboard was indentical to the English qwerty). I have forgotten to reboot my device then, what I did now, so the keyboard disappeared. Swithching back to English layout and rebooting the device and it works again.
