Actually such an aggressive response (from the GP, not you) is precisely the kind of thing I'd expect from someone who has an easy life. I live in pretty crappy conditions, including a crappy computer with crappy touchpad drivers. I just refuse to let such mundane things give me hypertension.
I have an old X1 Carbon that I use at the grunge travel laptop, like throw it in the backpack in a paper bag and go for a hike level of grunge.
Its trackpad is junk, phantom movements, zero palm rejection. I coded up some lock scripts so that it locks out the buttons if the cursor is moved. I fantasize about DeepTrack, the AGI that will finally give me trackpad bliss on a Linux desktop.
