Bug Description
Report originally created by following https:/
Touchpad worked perfectly in Ubuntu 17.10, with libinput 1.8.2.
After upgrading to 18.04 (libinput 1.10.4) touchpad frequently becomes unresponsive during normal operation, during which he mouse cursor and scrolling does not work. Lifting the finger and starting again makes it work until the next trigger.
Triggered apparently by premature palm detection which misdetects a slightly larger finger area as a palm event. Hence easily reproducible by placing a finger slightly flat.
