Solved Mouse aceleration with Xorg (UDEV)

[nunotex]

Hello,

New xorg-server option UDEV broke my old acceleration command:

xinput --set-prop ID "Device Accel Constant Deceleration" n

==> property 'Device Accel Constant Deceleration' doesn't exist, you need to specify its type and format

I not using any config files in /usr/local/etc/X11/xorg.conf.d/, it seems that xf86-input-libinput do auto-configuration.

Does anyone knows how to acelerate/decelerate mouse?

xinput list-props 10

Found it:

xinput set-prop 10 "libinput Accel Speed" -0.7

man 4 libinput:
Option "AccelSpeed" "float"
Sets the pointer acceleration speed within the range [-1, 1]

After upgrading to latest xorg-server, my mouse was waaaay too slow. This worked beautifully.
Thanks!
