I found when I use the hotkey to disable the touchpat and then I have to press the hotkey twice to re-enable it. This is symptom cannot be found if: 1) using Kubuntu. 2) plug the usb mouse (any port is ok) Because it can't be reproduced in Kubuntu, I think it should be an issue of unity-settings-daemon.
