As the Title indicates I have some problem with delicate movement of the mouse in Ubuntu fresh installation.

The jerkiness is shown more at small and slow movements when the mouse will move a 2 millimeters to any random positions every 5 centimeters of movements. My mouse is a Microsoft Sidewinder Gaming mouse.

Is there any driver I can use to fix it or any configuration? This is happening both in Unity or inside games and programs.

You may try this to check mouse parameters :

Open a terminal and Run this command:

xinput --list --short

output :

abcd@abcd-abcde:~$ xinput --list --short

Virtual core pointer

↳ SynPS/2 Synaptics TouchPad                id=11   [slave  pointer  (2)]

↳ Logitech USB RECEIVER                     id=12   [slave  pointer  (2)]

for me my pointing devices are a Lgitech usb reciver and synaptic touchpad

To list out device Properties :

xinput --list-props "SynPS/2 Synaptics TouchPad"

check properties like acceleration deceleration and see if they seam allright:

if you need to change any value like suppose this one :

Device Accel Constant Deceleration (267):   2.500000

using this command :

xinput --set-prop "SynPS/2 Synaptics TouchPad" "Device Accel Constant Deceleration" 1.5

You may have to play around with this number a bit to set it exactly as you need.

If you need to set this value automatically every time Ubuntu starts then :

create a .sh file

 #!/bin/sh

 "SynPS/2 Synaptics TouchPad" "Device Accel Constant Deceleration" 1.5

change the file to executable :

 chmod +x

and Put this in the start-up applications list.

that helped thank you :) –  Ba7a7chy Nov 6 '12 at 11:01

Looking at the mouse settings via the GUI, I found they were set to lowest possible acceleration, and lowest possible sensitivity. So I changed them using the GUI app and so far it's working just fine (after 5 mins)
