I am on an Asus Zenbook UX32VD in Ubuntu 12.10. Both in 12.04 and 12.10 I haven't been able to change the mouse speed (i.e. the "sensitivity" in the mouse/touchpad dialog). I can change the slider, but nothing changes.

This is a big problem for me, since the mouse speed is somewhat slow. Any suggestions?

The problem is both for the touchpad and mouse.

I dont have this laptop - so hence this comment. Maybe this Q&A can help - askubuntu.com/questions/130217/… . If you type synclient you have some parameters such as MinSpeed, MaxSpeed & AccelFactor that you can play with. Good luck. –  fossfreedom Oct 29 '12 at 9:35
    
I have installed LXInput from Softwarecenter. It's for LXDE but works also unter Unity. Anja –  Anja May 7 at 20:13

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"

EDIT: Another option: xinput --list-props 11 as 11 is the number that is shown above in its parent property (SynPS/2 Synaptic TouchPad).

Now reduce it's Property values to suit your need :

Device Accel Constant Deceleration (267):   2.500000

using this command :

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

EDIT: Another option: xinput --set-prop 11 267 1.5 11 is the device, just like from above, 267 is the id of the device property (Device Accel Constant Decleration) as you can see when device 11 is being listed all of properties being attached, and finally 1.5 is your desired speed.

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

xinput --set-prop "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.

I'm guessing you mean to put xinput --set-prop in the script, right? Anyway, it works :) Thanks! –  Felix Oct 30 '12 at 12:07
    
you are welcome :) –  Vikash Singh Oct 30 '12 at 15:56
    
I now have the same problem for my wireless logitech mouse with unified reciever. I can change the speed in the same way, but max speed (1) is way too slow! Any suggestions? –  Felix Nov 20 '12 at 12:11
    
Try increasing the acceleration property. <"Device Accel Velocity Scaling" 5> . I also have a Logitech wireless mouse and i can't see any direct speed property. all i got is acceleration and deceleration. Please tell what speed property your device is showing and also try to increase the value of speed beyond 1 and see if that works.. –  Vikash Singh Nov 21 '12 at 4:35
    
Thank you very much. My computer is now much more usable. –  John Satriano Sep 26 '13 at 18:04

Ubuntu 12.10 64-bit, Logitech cordless TrackMan

xinput did nothing for me.

xset q

to check settings

xset mouse 3 0

This sets the acceleration to 3 and the threshold to zero. This sets the acceleration to 3 and the threshold to zero. Not great settings but better than before.

If you enter a decimal value xset will round the values down. If the value is between zero and one and is rounded down to zero xset does not accept the value.

The man page says the settings will be lost on logout/reboot.

If you want to use fractional value, you can enter fraction (i.e. 3/2) instead of floating point number. It's weird, but it works. –  R Burny Sep 2 '13 at 1:16

I used the 'simple' profile to increase the mouse resolution without acceleration.

#!/bin/bash

device="Dell Dell USB Optical Mouse"
resolution_percent="241" # Greater than 100, use constant deceleration otherwise with profile -1. 

xinput set-prop "$device" "Device Accel Profile" 4 # Simple profile with threshold 0 allows constant scaling up
xinput set-ptr-feedback "$device" 0 "$resolution_percent" 100 # Set threshold to 0 and acceleration to $resolution_percent/100

You'll have to modify the script by using your particular device name. You can look that up by running xinput without arguments. Also the script has to be run each time the mouse is connected or when you start the system.

You can use these scripts to set the touchpad and mouse speed each systemstart:

#!/bin/sh
TP=$(xinput --list --short|grep -i touchpad|cut -f 1 | cut -d" " -f 5-|sed 's/\s\+$//g')
xinput --set-prop "$TP" "Device Accel Constant Deceleration" 1.5
xinput --set-prop "$TP" "Device Accel Velocity Scaling" 10

For me, I think 1.5 and 10 are suitable values for the touchpad.


I use a Logitech usb mouse too.
So for a Logitech mouse use this script:

#!/bin/sh
MOUSE=$(xinput --list --short|grep -i Logitech| cut -f 1|cut -d" " -f 5-|sed 's/\s\+$//g')
xinput --set-prop "$MOUSE" "Device Accel Constant Deceleration" 1.2
xinput --set-prop "$MOUSE" "Device Accel Velocity Scaling" 10

For me, I think 1.2 and 10 are suitable values for the mouse.
