Public bug reported:
I am running Ubuntu 20.04 on a new ThinkPad P14s AMD. I noticed that my
trackpoint was very laggy and choppy.
After a while I realized that the trackpoint is smooth as long as I am
not touching the trackpad (very difficult). Even with the trackpad
disabled in GNOME and the BIOS (which seems to only affect Windows) the
interference continues. Using the command "libinput debug-events" I can
see "POINTER_MOTION" events being registered despite the trackpad being
off. This seems to be what is causing the trackpoint lag.
Disabling the trackpad in the BIOS does not help. I have the same
behaviour on a 21.04 live USB session.
