Public bug reported:
After waking the computer from sleep (initiated by closing the lid), I
can't move the mouse using the touchpad. The touchpad will still click
and scroll, the mouse cursor is visible but it doesn't move. The
TrackPoint mouse still works, and plugging in an external mouse works.
If I turn the Touchpad off and on in the Mouse & Touchpad settings, then
it resumes working.
Stack trace in /var/log/Xorg.0.log (presumably attached) looks relevant:
(EE) [dix] SynPS/2 Synaptics TouchPad: unable to find touch point 0
(EE) BUG: triggered 'if (priv->num_active_touches > priv->num_slots)'
(EE) BUG: ../../src/synaptics.c:2644 in UpdateTouchState()
