3 finger tap middle button stopped working (XPS 13 9350 - 14.04)

Following the latest 14.04 HWE update that brought the 4.4.0 kernel update I can't get the trackpad on my XPS 13 9350 to recognise a 3 finger tap as the middle button.

I've tried running synclient TapButton3=2 which was what was needed to enable it before but no joy.

I do a lot of work on the command line and I'm really missing the double click to copy, 3 finger tap to paste.

I realise that most of the dkms extra modules are locked to only build for the 3.19.0 kernel and a most of them where probably backports from the upstream kernel anyway, but is there a timeline on when we can get a update to the OME packages to fix this?

I suspect it might be the same problem as with ubuntu 16.04

yeah, this is what I thought. See, you have two devices for only one touchpad:

DLL0704:01 06CB:76AE Touchpad


SynPS/2 Synaptics TouchPad

I have already reported this bug but it's still there.

The solution is to disable the second one. You need to create a file /etc/X11/xorg.conf.d/51-synaptics.conf
Here are the steps:

cd /etc/X11
sudo mkdir xorg.conf.d
cd xorg.conf.d/
sudo emacs 51-synaptics.conf

(replace "emacs" by you favorite editor) and then paste into the editor

Section "InputClass"
Identifier "touchpad ignore SynPS/2 Synaptics duplicate"
MatchProduct "SynPS/2 Synaptics TouchPad"
Option "Ignore" "on"

and restart

Cool, that works, my productivity is restored, and there is significantly less swearing going on round here.

Do you have a link to the bug?

I'm glad it worked for you as well.

THANK YOU!  For 2 things.  

 1.  The solution.  Lets hope it works.

2.  Posting a clear series of commands to cut and paste to actually implement the darn thing!  

So often you get solutions that read like "I just blurbled the xfig files using the diddly-daemon" and your average idot (me) has absolutely no clue how to replicate.  I can work through terminal and GEDIT, but I try hard not to.

So thank you for making the Linux world a friendlier place.
