Disable the TinkPad touch screen in Ubuntu

Originally having a touch screen is a fun thing, but the screen is cracked, causing frequent automatic clicks and affecting normal use. After installing Ubuntu, I searched for a long time and finally found a working solution. The main idea is to use ***xinput to disable the driver to solve ***, the disadvantage is that it fails after shutdown.

The environment used here:

• ThinkPad-S3-Yoga-14。
• Ubuntu 18.10

xinput

1. Type xinput in the terminal

Find the name of the touch screen in the list of input devices listed. Here is SYNAPTICS Synaptics Touch Digitizer V04 and its id: 14.

note:

• Every time you insert new hardware such as mouse and keyboard, the id number may change, so please use the corresponding id number
• In principle, this method is applicable to various brands to disable the touch screen, but the touch screen driver of each computer may be different, please choose from the list as appropriate.

2、 Set the enabled attribute of the touch screen to 0, disable the touch screen###

xinput set-prop 14"Device Enabled"0

3、 View the list of touch screen attributes###

xinput list-props 14

Configure automatic execution at boot##

It is obviously very troublesome to configure the above settings manually every time you start it. At this time, we can completely set it up automatically by writing a shell script and loading it on boot.

Create sh script###

Created here in the /home/windcoder/documents/ss directory

vi disableTouch.sh

Enter in the file:

#! /bin/bash

# Disable desktop touch screen

DESKTOP_DEV='SYNAPTICS Synaptics Touch Digitizer V04'

HAVE_DISKTOP_TOUCH=`xinput list | grep "$DESKTOP_DEV"`if["$HAVE_DISKTOP_TOUCH"!=""];
then
 echo "The touch screen starts to turn off"if[`xinput list-props "$DESKTOP_DEV" | grep "Device Enabled" | awk  -F ':' '{print $2}'`==1]; 
 then
  echo "The touch screen is turning off"
  xinput set-prop "$DESKTOP_DEV"'Device Enabled'0
  echo "The touch screen is turned off successfully!"else
  echo "Shutdown failed. . ."
 fi
else
 echo "Program closed"
fi
echo "Completely over"

The echo statement in the script can be deleted, and it is only added here to test the script.

Configure boot

Use in the terminal:

sudo vi /etc/profile

Add at the end:

. /home/windcoder/documents/sh/disableTouch.sh

Save and exit, and finally execute the following:

source /etc/profile

Restart at this time to find that the corresponding driver has been automatically disabled.
