fwiw, I was referring to the synaptics options that are there but often unused.

synaptics pointer acceleration is... complicated and almost impossible to
reproduce. Amongst other things, it depends on your screen resolution.

<span class="quote">> Okay, but why can't I set the flat profile from the configuration?</span >
we only expose config options when there's something to configure. In this
case we only have one profile, so no point to expose an option.

maybe. it's always hard to infer "feel" from pure recording and on top of
that i'm bottlenecking quite badly, so any help is appreciated. The
acceleration code is all in src/filter.c and it's not that hard to
understand (there are plenty of comments, anyway).</pre>
