1. looking for mouse device id or name




$ xinput --list

⎡ Virtual core pointer                      id=2    [master pointer  (3)]

⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]

    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]

    ↳ CHESEN USB Keyboard                       id=8    [slave  keyboard (3)]

    ↳ CHESEN USB Keyboard                       id=9    [slave  keyboard (3)]




2. setting mouse sensivity




$ xinput --set-prop 10 "Device Accel Constant Deceleration" 4



don't know why there are two same names so have choosen id by random. and it worked out.


3. telling system to do this after logging in


create script:



#!/bin/bash

xinput --set-prop 10 "Device Accel Constant Deceleration" 4

xinput --set-prop 10 "Device Accel Velocity Scaling" 1



then run command:



$ gnome-session-properties



and add the script to the list.

don't forget about chmod +x.
