--- Comment #4 from Britt Yazel <bwyazel at gmail.com> ---
I have a synaptics touchpad. The one in the Dell XPS 13 9333.

I am testing the libinput 0.17 with the low velocity patch, and I think it is
an improvement. That being said, it still feels a bit off. If I get the
acceleration right for medium speed cursor movements, a quick movement sends me
flying over my target. And if I set it right for quick movements, medium speed
movements cause me to undershoot. Slow cursor speeds seem to be ok now though.

I am not sure how to do a evemu-recording, you might need to specify a bit more
how to do it.

Lastly, what is the rationale against having separate settings for both
acceleration and velocity, and rather this dynamically changing acceleration?
