Hi, thanks for the comments. The acceleration schemes and coordinate
filters are different in the ws+wsmouse setup, so it's inevitable that
the feel of it is different. Even if I could reproduce the synaptics
behaviour, I wouldn't want it. By and large, it is usable and
acceptable, but I think it has flaws - which lead to a lack of
precision, especially in short movements.
However, if it is only the base speed of the pointer that doesn't suit
you, there is a simple way to adjust it by changing the value of
wsmouse.tp.scaling
in wsconsctl(8).
Scrolling is a different thing. The new driver has actually a
comparatively high threshold before it starts scrolling, and the scroll
speed is moderate. Maybe I'll lower the threshold, that's not settled
yet.
