I'm using ubuntu 16.04, after an update, my touchpad stopped working properly.

Tap to click no longer works, the cursor speed is lower than it was, and scrolling got reversed.

I was using libinput before the update, I had a problem and someone suggested to install it to fix the problem, and it did, https://askubuntu.com/a/886098/625501

I tried opening the file /usr/share/X11/xorg.conf.d/90-libinput.conf put I think it's messed up or something, I'm not sure.

It looks like this

I tried sudo apt-get dist-upgrade and then sudo apt install xserver-xorg-input-libinput but it says it's up to date.

Edit the /usr/share/X11/xorg.conf.d/90-libinput.conf

And add to the touchpad section after Driver "libinput"

Option "Tapping" "True"
Option "NaturalScrolling" "True"

Then log off and on. This will enable tapping and reverse scrolling.

  • Oh, that touchpad section, I Was looking at "Inputclass", thinking there was something wrong. It works now, thank you. BUt the cursor speed is still slow. – MichaelX Aug 15 '17 at 9:22
  • You can adjust cursor speed too, but I am leaving now. Meanwhile you can ask "how to adjust cursor speed in libinput" as a new question. If nobody answers, I will look at it tonight. – Pilot6 Aug 15 '17 at 9:25
