If that can help anyone, here’s part of my xorg.conf:
Section "InputDevice"
Driver "wacom"
Identifier "cursor"
Option "Device" "/dev/input/wacom"
Option "Type" "cursor"
Option "Speed" "3.0" #I want the speed to be 3 times faster
EndSection
The speed parameter’s default value is 1. Putting it at 3 means that I have a wacom mouse that behaves roughly as fast as my logitech mouse. Pretty important when you have a 1920×1080 screen and the wacom tablet surface is only a few inches.
