ThinkPad E540 turn off TrackPad

[UltraCookie]

Solution:

Props to avj the hint on xinput.

Open a terminal by pressing [Ctrl+Alt+T].

To get a List of mouse and keybord devices do:

Code:

xinput --list

output:

Code:

⎡ Virtual core pointer                       id=2   [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                 id=4   [slave  pointer  (2)]
⎜   ↳ SynPS/2 Synaptics TouchPad                 id=10   [slave  pointer  (2)]
⎜   ↳ TPPS/2 IBM TrackPoint                      id=11   [slave  pointer  (2)]
⎣ Virtual core keyboard                      id=3   [master keyboard (2)]
    ↳ Virtual core XTEST keyboard                id=5   [slave  keyboard (3)]
    ↳ Power Button                               id=6   [slave  keyboard (3)]
    ↳ Video Bus                                  id=7   [slave  keyboard (3)]
    ↳ Integrated Camera                          id=8   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard               id=9   [slave  keyboard (3)]
    ↳ ThinkPad Extra Buttons                     id=12   [slave  keyboard (3)]

Get the device ID of the device you want to edit. I want to edit the TouchPad properties so the ID is 10

To see the device properties do:

Code:

xinput list-props 10

This will give out a pretty long list of properties. We are interested in the deceleration of the courser. The properties controlling this are at top of the list and are called:

Code:

Device Accel Constant Deceleration (262):    2.5
Device Accel Adaptive Deceleration (263):    1

To stop the courser from moving when the Touchpad is used heavily increase these values (I put both to 1000, maybe less also works).

Code:

xinput --set-prop 10 "Device Accel Constant Deceleration" 1000
xinput --set-prop 10 "Device Accel Adaptive Deceleration" 1000

To make sure this gets done on every boot do:

Create an empty file called 'no_touchpad.sh'

Open it in a text editor of your liking and copy/paste this code into it:

Code:

#!/bin/bash

# For TouchPad to stop moving the courser

xinput --set-prop <your ID> "Device Accel Adaptive Deceleration" <your value>
xinput --set-prop <your ID> "Device Accel Constant Deceleration" <your value>

exit 0

Put the file in a directory of our liking and make it executable by doing:

Code:

sudo chmod ugo+x /your/directory/no_touchpad.sh

Go to the main menu and search for 'startup' and open 'Session and Startup'.
Add a new startup with the command:

Code:

bash /your/directory/no_touchpad.sh

If the changes where made and the touchpad can still move the courser you need to put the two values even higher or this solution does not work on your device.
