On my 16, the palm rejection fails if my palm touches the touchpad just slightly at the edge. I don’t ever use this are of the touchpad for actual touches. Is it possible to “reserve” this area for palm rejection (to avoid the issue just moving inwards)?
With GNU/Linux, anything is possible except working palm rejection.
I am mostly kidding, but have you had any real luck with it or are you still just dealing with it? I find putting a .7-.8 second delay on the touchpad while typing is the best solution, but your mileage may vary.
