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.
