Setting Mouse or TouchPad Sensitivity in Ubuntu Linux

Problem

On Ubuntu Linux (14.04) your mouse or touch pad move too fast even though you have set the sensitivity level to its lowest setting.

Solution

Here are the steps. See the link at the bottom of this post for more details.

1) Use the ‘xinput’ command to get a list of pointing devices.

xinput --list

Virtual core pointer                  id=2    [master pointer  (3)]
    Virtual core XTEST pointer        id=4    [slave  pointer  (2)]
    A4Tech USB Full Speed             id=10   [slave  pointer  (2)]
    A4Tech USB Full Speed             id=11   [slave  pointer  (2)]

2) Use the same command to set the pointer speed. For example:

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

3) To set the mouse at startup, create a shell script.

#!/bin/bash
xinput --set-prop 10 "Device Accel Constant Deceleration" 4

Your settings may vary. My trackpad and mouse required different values.

4) Use the gnome-session-properties to add the script to the list of startup scripts.

That should be it. Your pointing devices should work better now.
