Ubuntu – Keyboard not working after update to 18.04

18.04keyboard

I updated my laptop to 18.04 from 17.10 . The keyboard inputs are recognized only in the login screen after booting. Keyboard also works fine if I switch into the terminal from the login screen. But when logged in no keystrokes are perceived.

Installing xserver-xorg-input solved my problem !

Expanding on the above for the inexperienced, it is possible to turn on the on-screen keyboard (accessibility menu) as it is likely that external USB keyboards will also not work. After that perhaps the command

sudo apt-get install xserver-xorg-input-all

will do it. You need to shutdown and reboot each time (closing the lid usually just puts it to sleep).
