Restore tap to click in Ubuntu 16.04 on Dell XPS 13

  • 772

This question follows on from this one about natural scrolling.

Before I made changes, I could simply tap on the trackpad of my Dell XPS 13 to generate a click. Now I have to explicitly click, which requires extra effort. I would like to restore tap-to-click if that is possible.

I have a Dell XPS 13 which, by default, has a very sensitive trackpad. As you are typing, if you brush the trackpad by accident, the trackpad considers it as a click and the text insertion point jumps to wherever the mouse happens to be. I found and installed this fix for this issue:

sudo apt-get install xserver-xorg-input-libinput

This inverted the scrolling direction, so I also edited the entry for MatchIsTouchpad in /usr/share/X11/xorg.conf.d/90-libinput.conf:

Section "InputClass"
        Identifier "libinput touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
        Option "NaturalScrolling" "true"
EndSection

With this new setup, tap-to-click does not happen. Is this inevitable? Is this the only way to prevent accidentally brushing the trackpad from generating a click? Or is it possible to regulate the sensitivity so that a deliberate tap is treated differently from a fleeting touch?

    Adding...

        Option "Tapping" "True"

    ... to the entry for MatchIsTouchpad does the trick.
