Today I upgraded to 18.04 from 16.04. Everything seemed to work fine, I only had to redo some settings. One of these is that I remap some keys, e.g y to z and vice versa.
After a reboot the keyboard stopped working. I found out that the super key is stuck. Pressing
l, for example, locks the screen. Unfortunately,
enter is affected as well, making it impossible to c&p commands into terminal.
On top of that, there's a bug restricting visual keyboard to few apps only.
What can I do to unlock the super key? Might it be that changing the key mapping caused the issue?
