Title:
two finger touch on touchpad part active, even though it was
deactivated
Status in linux-meta-hwe package in Ubuntu:
New
Bug description:
Disabled touchpad on Lenovo t460s notebook over "Mouse and Touchpad
setting". Touchpad seems to be deactivated in normal behaviour, but
two finger touch on touchpad seems to be part activ while press left
touchpad button.
So if I press left touchpad button while my both hands lays on
touchpad because of 10 finger typing, it seems it notice 2 touches on
touchpad (2 finger touch). I am a trackpoint user, so typing and mouse
interactions are quite good solution, but touchpad must be deacitvated
while working, because both hands lay down on touchpad will cause
mousepointer interactions. So i decided to disable it. But if boths
hands lay on touchpad and I click the left touchpad button for example
to mark a part of text, it will be like the left button is locked.
This behaviour will go away if i do not lay down my both hands on
touchpad. So it seems that touchpad is not fully deactivated, the 2
finger touch seems part active.

same behaviour.
