The settings, have exactly these options you posted. I hope that is to make not necessary answering the other questions.
The issue, is that "Pointer threshold" is limited to 20, while I want it to be a higher value.
Basically, I don't want any acceleration, I want the pointer to move, accordingly to the mouse movement, without any acceleration.
In other words, when I move the mouse(well touchpad, but same crap) distance X, I expect the pointer to move distance Y on the screen. Without any relativity to the duration of the movement, velocity of the mouse, or anything else. Whenever the mouse is moved X distance, pointer moves Y distance. 2X - 2Y, etc'.
That can be achieved, by acceleration 0, I suppose, although minimal is 0.1. Well, 0.1 is close enough to 0, I won't complain.
