  ======

  using xinput --query-state can actually see the button press event

  ⎡ Virtual core pointer id=2	[master pointer (3)]
  ⎜ ↳ Virtual core XTEST pointer id=4	[slave pointer (2)]
  ⎜ ↳ syntp id=6	[slave pointer (2)]
  ⎜ ↳ ELAN Touchscreen id=11	[slave pointer (2)]

  #xinput --query-state 11
  2 classes :
  ButtonClass
   button[1]=up
   button[2]=up
   button[3]=up
   button[4]=up
   button[5]=up
  ValuatorClass Mode=Absolute Proximity=In
   valuator[0]=398
   valuator[1]=1652
   valuator[2]=5
   valuator[3]=3
   valuator[4]=0
   valuator[5]=399
   valuator[6]=1653

  #xinput --query-state 6
  2 classes :
  ButtonClass
   button[1]=down
   button[2]=up
   button[3]=up
   button[4]=up
   button[5]=up
   button[6]=up
   button[7]=up
   button[8]=up
  ValuatorClass Mode=Relative Proximity=In
   valuator[0]=1
   valuator[1]=394

  touchpad's button and touchpanel's
  valuator[2] and valuator[3] will changed after we press the button (or monitor)

  Also I found press "super" on keyboard will recover the
  touchscreen/touchpad loss.
