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.
