Ubuntu – “Disable Touchpad while typing option” gone in Ubuntu 16.04 LTS

16.04touchpad

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.
