Update October 11, 2021 = Touchpad issue corrected with a reboot of the Laptop.
I was working on my laptop recently. I pressed something by mistake and can't remember what I did. After that, my touchpad does not move at all when I slide using one finger. But it does when I do with two fingers as if the function has changed to one extra finger. Similarly, the function of two keys that is 'scroll and zoom', only happens when I use three fingers. I have tried resetting the touchpad to default settings several times but it still doesn't get fixed. Can anyone help me, please?
