(picking up discussion left off in other thread)
Note: I now cannot get any response from my trackpad at all (but I CAN use my trackpad inside of lightdm).
Tailing a bunch of logs, nothing interesting happens when I interact with my trackpad (syslog used to print out a lot of lots when I used my trackpad):
tail -F /var/log/{dmesg,syslog,udev,kern.log}
