Upgrade of libinput on a new Solus installation disables key input from the laptop keyboard inside a desktop environment, (same result when switching from Budgie to MATE).
libinput is upgraded from 1.6.0-10-1-x86_64 to 1.9.0-14-1-x86_64
Input from the integrated keyboard works fine inside the virtual console terminals, tty2 etc. after pressing e.g. Ctrl + Alt + F2 on an external keyboard.
Laptop: Compaq CQ58
