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.
