Keyboard input is not working in 18.04. It always works till I unlock - type in password. After that it works only sporadically.
A stop icon is also displayed sometimes over the screen. Why does this happen? I think this could be a software problem because this never occurs while typing in password. How do I fix this? Screenshot attached.
I'm using a lenovo ideapad 320, ubuntu is the only OS in the laptop.
This problem seems to go away when Florence is running.
Update: This affects the virtual keyboard as well. This problem only occurs in workspaces.
