It just happened right now. I've saved dmesg output and the X's log.
(Attaching them.)

There are no nvec messages in dmesg. But there are two "ec" messages.
Are they important?

I've checked once again the behavior of the touchpad when this happens:

movements don't work,
but scrolling doe work (at the right side of the pad with a single finger),
clicking does work (by hitting the pad, or with the buttons underneath -- both work).

I tried to press F9: this turned the tocuhpad competely off. Then I
pressed F9 once again: and this resulted in the same errpneous
situation: movements don't work, other things do work (scrolling,
hitting).

So it's not a matter of F9. And it's not matter of complete
disconnection.

Please tell me:

What to do further to diagnose the source of the error?

  touchpad stops working (moving the pointer doesn't work)

Bug description:
  Sometimes, in my Ubuntu 12.04 system on Toshiba AC100 (ARM), the
  touchpad doesn't react to movements anymore: i.e., I move the finger,
  but the pointer doesn't move (it is even being hidden because there
  are no movements).

  The buttons under the touchpad do work.

  Also, when I switch windows etc. the pointer does appear, and then
  hides again. So it's not a problem of the pointer in X, it's a problem
  either of the touchpad physically, or of the driver for it.

  I usually notice this when I'm working with a browser (Firefox),
  perhaps even with a map (like Google map) inside it. But this may be
  not related to the causes of the bug.

  A workaround: attach a USB mouse. (It works.)

  As I've found out somewhere under /sys/, the device is an Elantech
  touchpad, and the corresponding driver is psmouse.

  I couldn't find anything relevant in the dmseg output.
