I found more grist:

https://www.reddit.com/r/linuxquestions/comments/7r7a5e/terminal_typing_on_its_own_only_in_tty_terminals/

(I personally have neither input_polldev nor peaq_wmi loaded here--in
fact the latter is inexistant on this machine according to modinfo).

Actually I'm uncertain peaq_wmi is a loadable module. If you enter,
however, "input_polldev spam" or "input_polldev bug" into a search
engine, it almost feels like hitting pay dirt.
