Disable double tap (but keep one tap to click enabled) on touchpad

I normally used the intuitive touchpad options on my MacBook Air under macOS (i.e. tap to click, three finger swipe to change desktops, three finger swipe up to show the window manager...) and want to disable what Ubuntu registers as dragging when I select text by double tapping it and moving the cursor.

How do I do that? I couldn't find any similar questions and don't even know how to search for the answer.

Yes that also means double tapping desktop icons to open them. I guess I'll just double click them without tapping.

If you're using X and libinput, I think that you're looking for the TappingDrag option which is described at https://wayland.freedesktop.org/libinput/doc/latest/tapping.html#tap-and-drag and shown in man libinput:

       Option "TappingDrag" "bool"
              Enables or disables drag during tapping behavior ("tap-and-drag"). When enabled, a tap followed by a finger held down causes a single button down only, all  motions  of  that  finger  thus
              translate into dragging motion.  Tap-and-drag requires option Tapping to be enabled.

You might be able to configure it by running:

gsettings set org.gnome.desktop.peripherals.touchpad tap-and-drag false

per How to disable the "tap dragging"-feature in Ubuntu 18.04 (libinput) without disabling "tap to click"?

Please, state your hardware in the body.

Code in /etc/X11/xorg.conf.d/10-synaptics.conf from [SOLVED] Synaptics double-tap problem - Linux for another attempt to get double-tap to work in your hardware

Section "InputClass"
        Identifier "touchpad catchall"
    Driver "synaptics"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Option "TapButton1" "1"
        Option "TapButton2" "0"
        Option "TapButton3" "0"
    Option "VertEdgeScroll" "on"
    Option "MaxDoubleTapTime" "100"

Not considering wipe with three finger here.

Stability: still much to improve for OS X level

Differential solution: KDE which has builtin configs there so maybe little better support, discussed here for KDE

OS: Ubuntu or Debian 8.x/9.x
Window manager: Gnome 3.14 or one earlier
