Many thanks. I'll work through that - bit by bit (It's years since I did techie work).

If you then run

   xev

you get information about hardware that might move the mouse pointer.

Perhaps the hardware is broken. I guess that assumed the software should be
fishy, it won't display something, when the mouse pointer moves, but this
not necessarily is ensured, so better disable the mouse pad and connect an
external mouse for testing purpose.

Run

   xinput --list

and then

   xinput disable NUMBER_OF_THE_TOUCHPAD

An example, since I don't have a touchpad, I show how to disablen and
enable my optical mouse.

   xinput --list
   ⎡ Virtual core pointer                       id=2    [master pointer  (3)]
   ⎜   ↳ Virtual core XTEST pointer                     id=4    [slave  pointer 
 (2)]
   ⎜   ↳ USB Optical Mouse                              id=8    [slave  pointer 
 (2)]
   ⎣ Virtual core keyboard                      id=3    [master keyboard (2)]
       ↳ Virtual core XTEST keyboard                    id=5    [slave  
keyboard (3)]
       ↳ Power Button                                   id=6    [slave  
keyboard (3)]
       ↳ Power Button                                   id=7    [slave  
keyboard (3)]
       ↳ AT Translated Set 2 keyboard                   id=9    [slave  
keyboard (3)]

To disable the mouse I need to run

   xinput disable 8

and to enable it

   xinput enable 8

Ralf
