Custom accel-profile for mouse?

[Lopolin-LP]

libinput has the option to use a custom acceleration profile for pointer devices, but I don't see a way I could take advantage of it from within the niri configuration files. Is there another way I could get it working, or should I make a feature request?

Hey,

Everything libinput related, Check out input-remapper.

I believe it allows you to configure custom curves and acceleration.

I just tried it out, so far it's pretty good, but not perfect:

• It affects "raw mouse input", so in games I notice that my curves are applied there too. On one hand that's probably the intention of the app, so not a bug, but I also can't disable that behavior.
• I can't customize the curve further than "in the beginning a bit faster/slower, and then in the end keep it the same/suddenly go faster".

Still, thanks for the suggestion! It's pretty close to what I imagined, and I will probably use it if nothing better comes up.
