Maybe you were a double acceleration victim before - it's by design in
I also added a small fix, so it now also scales for a (presumed)
synaptics reporting rate, and tries to get the algorithm's accel
parameter right. Maybe it's better now.

Fun fact: As long as you're in profile 1 (device-dependent), xset won't
do anything. X accel default settings seem to make no sense to the
synaptics accel, so it left them side-by-side.

Guess why I added accel stuff to xorg.conf.d ;) Of course, your average
DE will simply over-xset it all ;(

Nice to hear - that's exactly what it should achieve.
