I've just noticed that the gpointing-device-settings step needs to be
done after rebooting, touchpad works after a reboot. Another bug?

Temporary workaround:
sudo apt-get install gpointing-device-settings sudo gpointing-device-
settings
From there, set the touchpad to off. and make sure to keep the System -
Preferences - Mouse - Touchpad - Disable touchpad while typing
setting off, otherwise the touchpad will just be re-enabled
