I am trying to change the mouse acceleration for my laptop trackpad. Using the command
xinput --set-prop 15 330 0.55
does what i want, but it resets after rebooting, so i tried creating a .conf file in the /etc/X11/xorg.conf.d directory following the arch wiki entry on mouse acceleration.
The content of 50-mouse-acceleration.conf is:
Option “AccelSpeed” “0.55”
But after rebooting the mouse acceleration is reset back to the default.
