This option, which was present in the "Mouse and Touchpad" settings panel in previous versions, is for some reason absent in 16.04 LTS. Does anyone know why this is, and/or how to fix it? Thanks.

I found a similar question AskUbuntu which provided a link to the details needed to solve this issue.

In short, edit your quirks file:

sudo vim /usr/share/X11/xorg.conf.d/51-synaptics-quirks.conf

And add the following to the end of the file:

# Disable generic Synaptics device, as we're using
# "DLL0704:01 06CB:76AE Touchpad"
# Having multiple touchpad devices running confuses syndaemon
Section "InputClass"
        Identifier "SynPS/2 Synaptics TouchPad"
        MatchProduct "SynPS/2 Synaptics TouchPad"
        MatchIsTouchpad "on"
        MatchOS "Linux"
        MatchDevicePath "/dev/input/event*"
        Option "Ignore" "on"
EndSection

Now restart Xorg:

sudo systemctl restart lightdm

Now, just start syndaemon as usual:

killall syndaemon
syndaemon -i 0.50 -m 0.10 -d -K

Note: For some reason, two-finger scrolling didn't work until I fully rebooted my laptop, but it eventually started working.

Edit

I eventually installed touchpad indicator like another answer suggests, when I had to switch to a different Dell laptop, and this fix no longer worked.

This works fine for me (ubuntu 16.04): 

sudo add-apt-repository ppa:atareao/atareao  
sudo apt-get update  
sudo apt-get install touchpad-indicator

Launch touchpad-indicator, and go to the Actions menu. Select the Disable the touchpad on typing option.

Adding to DevNull's solution, I added this command:

syndaemon -i 0.50 -m 0.10 -d -K

to my startup application's command. In this way, it still works even after rebooting.

When searching the internet for an answer to this problem, I found a page that suggested using syndaemon to accomplish this (found here: http://www.webupd8.org/2009/11/ubuntu-automatically-disable-touchpad.html). I used the command "syndaemon -i 2 -d -K" in terminal for my needs. This command disables the touchpad while typing for two seconds (-i 2), except when modifier keys such as Alt or Shift are used (-K).

Hope that helps!

The touchpad settings are gone probably because libinput has been installed. It does not have GUI settings.

In Ubuntu 16.10 it is installed by default.

You can either remove xserver-xorg-input-libinput or xserver-xorg-input-libinput-hwe-16.04 to get GUI back, or use a config file for this kind of settings.

In gnome exists an extension that works perfect: https://extensions.gnome.org/extension/131/touchpad-indicator/
