Well, i’ve upgraded latest Dell’s laptop to Ubuntu 18.04 and my keyboard suddenly stuck when typing and not reacting on pressing keys. Only alt-tab’ing helps and this happened to me when i’ve used to chat in Telegram messenger (snap installation).
I’ve found a solution for this 🙂
sudo apt install xserver-xorg-input-all
Just install this software and reboot your pc.
If i remember right, some parts of dependencies are not installed properly, but still that fixed my issue.
Also I’ve deleted telegram messenger that was installed via snap and installed base Ubuntu Store version.
snap remove telegram-desktop
