I am a little surprised this prominent bug seems so "quiet". To emphasize my last post:
SOLUTION! for this bug is: lightdm starts a syndaemon instance which MUST be terminated upon session startup. Otherwise two syndaemon instances compete for disabling/enabling touchpad, and will eventually get out of sync. This was simply overlooked when switching from gdm to lightdm as login manager. PLEASE FIX.
