GNOME 3.16: Mouse acceleration changed?

Hi,

I'm not really sure how to describe the change, but I'm pretty sure that something about the mouse acceleration has changed with GNOME 3.16. Did anyone else notice this? Right now I'm using an USB mouse, so I don't even have an acceleration option in the menu, so I'm not sure what to make of this. Has anyone of you guys investigated this any further and can, for instance, nail this to a particular commit and/or setting?

Thanks in advance!

Best regards,
Karol Babioch

I've reported this [1], hopefully some developer will have a look at this.

I also noticed this. I just adjusted the pointer speed settings to slower in Mouse & Touchpad settings.

This is definitely an issue for many users: http://www.reddit.com/r/archlinux/comme … chs_repos/

Dropped the following into /etc/X11/xinit/xinitrc.d/50-fix-gnome-mouse-accel.sh (don't forget chmod +x)

#!/bin/bash
/usr/bin/xset m default

But again, a hack... I am also convinced that the gnome update did this (and not libinput), and there's absolutely nothing in the gnome-shell changelog or git log saying anything about mouse/cursor speed ...

You are right and wrong at the same time. GNOME 3.16 switched to libinput, so that's indeed a change in GNOME which made you notice it, but fundamentally it comes from libinput. Besides this, libinput has a bug which introduces a deadzone, so any attempt at gaming is a fail.

In order to get the old behavior, you can remove the libinput X11 driver,

# pacman -Rcs xf86-input-libinput

Good to know, thanks; makes sense that libinput would have a different default behaviour (non-zero acceleration for instance), e.g. specifically for touchpads. It could also be that the value in gsettings for mouse acceleration has changed at the same time than using libinput.

Anyone knows what the previous mouse acceleration value was (i am guessing zero) ? If so, does setting mouse acceleration to the minimal value in the gnome settings revert the old behaviour ?
