Touch pad stopped working after installing Ubuntu 14.04 while it was working on Windows 8.

I tried to install by using the following command:

sudo apt-get install synaptics

it displays the message:

xserver-xorg-input-synaptics is already the newest version.

I have a dell inspiron 3451 laptop

Please suggest.

You could remove the touchpad and then re-install. Sometimes that fixes issues like that.

See if it's listed on xinput with

xinput list

If it is, check to see if it's enabled or not. If it's not on the list, then uninstalling and reinstalling the drivers with apt-get seems to be the best option, given I don't know your hardware specs.

What laptop do you have, and what type of touchpad?

  • Well when I type : xinput list , it shows : ↳ SynPS/2 Synaptics TouchPad id=14 [slave pointer (2)] – Lor Wem Nov 26 '15 at 12:58

    @LorWem That means the device is recognized, but it's not working properly. Try uninstalling and reinstalling the drivers for it if you're having any issues. [If you just want to temporarily disable it, you can do xinput disable 14, and then it'll be disabled until you restart your system.] – Anxionos Dec 02 '15 at 13:39
