I am running Debian stretch (with a newer kernel, 4.14) on an HP 8460p. The trackpoint (pointing stick), when pushed left or right, seems to send a very long stream of F9 or F10 keys, possibly along with other keys, preventing me from using the keyboard until I unjam it by switching VTs. How can I disable the trackpoint functionality? It doesn't seem to have an associated xinput device, and the properties on "SynPS/2 Synaptics TouchPad" or "AT Translated Set 2 keyboard" don't mention any trackpoint settings.
