The suggestion to delete the existing session.conf and let lxqt create a new one was good. It worked for a while, but natural scrolling broke again today (2021-02-20). Last time I had the computer on (2021-02-18) natural scrolling was working fine.
Could this be a problem with the USB bus? The session.conf file has a date stamp of 2021-01-30, so it has not been altered.
