In my case if I logout then I can log back in but the touchpad no longer accepts tap input and I have to use the left button adjacent to the touchpad instead. As you say restarting X returns the system to normal touchpad behaviour.
I was not up to date enough - I just updated and now have the same behaviour as above - i.e. after logout no keyboard input.
By the way great to see administrator mode working now - excellent!
