When moving the pointer (touchpad), it appears to "freeze"- if i lift off the
touchpad and try again, the pointer usually works. however, it sometimes also
seems to be suck in a "selection" (i.e. depressed) mode, and won't exit until i
make a click.
During these times, the following messages are of course printed to the
journal:
Jun 26 22:48:01 cylon /usr/lib/gdm/gdm-x-session[1649]: (EE) kernel bug: Touch
jump detected and discarded.

for details
I have two touchpads showing up; apologies as I don't know which one it'd be.

This is for a Samsung NP940Z5L-X01US ("ATIV Book9 Pro"). Regretfully I don't
have a measuring device on me so I can't get the dimensions of the touchpad in
mm (if there's a way to get this from dmidecode, etc. do let me know)</pre>
