I have the same problem with Kubuntu 04/20.1 LTS after upgrading from Kubuntu 04/18.x LTS. I'm using xserver-xorg-input-libinput as a driver. I've tried other drivers but without success. No change after installing the xserver-xorg-input-evdev driver. And after installing the xserver- xorg-input-synaptics driver, the touchpad worked again, but the keyboard didn't. I don't understand why this bug is classified as low importance. I only use my laptop as a mobile device and cannot use it without a touchpad. And now you have to carry a mouse with you everywhere.
