How to disable Touchpad permanently

J_angel2000 · 08-30-2014, 07:19 PM

I have an Ubuntu 14.04 and a new Sony Vaio with an annoying huge touchpad. How can I disable it forever?

On system configuration it works but just until next reboot. Then it reenables itself again.

On the Bios I don't find any option to disable it.

Thanks a lot!

Are you using the Gnome DE? If so, you can disable using 'deconf-editor' as described here:

In particular...

Quote:

In order to disable touchpad permanently on your laptop, invoke dconf-editor.
$ dconf-editor

Then go to "org"->"gnome"->"settings-daemon"->"peripherals"->"touchpad" on dconf-editor, and uncheck "touchpad-enabled" field

Hey, I have done it that way too but after rebooting it gets enabled by itself again

Find out how it connects and either remove support for it or blacklist the driver. Might be possible to disable in bios too.

Then maybe an executable script in ~/.config/autostart/ directory that executes

Code:

synclient TouchPadOff=1

which will take effect after logging in.

I'm very newbie, ferrari. How can I do that?

Since you're an Ubuntu user, the easiest way to do this is to use 'Startup Applications'

You'll want to use the command given previously.

Another example here:

Hope that helps.

Hi,

I use this script;

Code:

~$ cat touchpad.sh

----cut-----
#!/bin/bash

# touchpad.sh Written by Atanas S / Siteground Support Team

# First we need to get the device ID from the xinput
# if it does not work for you, you may need to set the cut -f option to another number
# I would suggest that you test the command in your terminal first to see the result
# It should output an integer usually between 8-15, at least on my lap top :D

getdev=`xinput list |grep pointer |grep PS |cut -f 2`
devid=${getdev/id=/}

#Second we need to get the device status, if it is enabled or not

# if it does not work for you, you may need to set the cut -f option to another number
# I would suggest that you test the command in your terminal first to see the result
# It should output 0 or 1

getstatus=`xinput list-props $devid |grep 'Device Enabled' |cut -f 3`

#once we get the device status depending on the status we set it the other way arround
        if [ "$getstatus" == "1" ]; then
        newstatus="0"
        else
        newstatus="1"
        fi
`xinput set-prop $devid "Device Enabled" $newstatus`
----end cut------

I just run the script locally via Kconsole vt, no issue. You can use the same script to toggle the touchpad back on.
Hope this helps.
Have fun & enjoy!

Not a permanent solution, but I've put aliases in ~/.bashrc:

Code:

alias tpoff='synclient TouchpadOff=1'
alias tpon='synclient TouchpadOff=0'

It's more often off than on, but not always.
