The trackpoint and associated mouse buttons recently stopped working on my Lenovo P50 laptop. The recent automatic updates (Ubuntu 20.04.3 LTS, October 2021) played havoc with the trackpad, but that was fixed by re-installing libinput and synapics. Unfortunately, this did not fix the trackpoint and its associated mouse buttons.

I've searched stack exchange, and existing knowledge of this is pretty old (relating to bugs from a few years ago), or relating to different problems (intermittent trackpoint failure or issues with the trackpad, not trackpoint).

Would anyone happen to know if there is a standard way to fix this? Perhaps I missed something.

Edit: to add to the weirdness, the trackpoint works again after resuming from suspend. However, it will randomly stop working some minutes later.

I have the exact same issue on a Lenovo x1 Tablet running Ubuntu 22.04, even with the after resuming temporary fix. I haven't figured out yet what might be the problem as it happens even on different kernel versions.
