18.04 broke natural scrolling
Solution 1
So after re-installing the Synaptics driver I took another look at my settings and now I feel really stupid. I figured it out.
I don't recall there being separate options in 16.04 for "mouse" and "touchpad", or if there were then I properly set my mouse up so long ago, that when I updated to 18.04 (and it reverted my touchpad settings) I had completely forgotten.
Toggling the appropriate setting worked as expected
Solution 2
Regarding the horizontal scrolling discrepancy, for those who want to keep natural scrolling on, there is a fix in this question: Inverted Horizontal scrolling ubuntu 18.04
Specifically I used this script and an .xsessionrc
in home directory to run the script at startup.
export id=`xinput list | grep -i touchpad | awk -F"=" '{ print $2 }' | awk '{ print $1 }'`
xinput list-props "${id}" | grep "Synaptics Scrolling Distance" | sed 's/[^0-9 \t-]//g' | while read a b c;
do
echo "${a} ${b} $((${c}*-1))";
xinput set-prop "${id}" "${a}" "${b}" "$((${c}*-1))"
done
Solution 3
Running these two commands in the terminal worked for me:
gsettings set org.gnome.desktop.peripherals.mouse natural-scroll false
gsettings set org.gnome.desktop.peripherals.touchpad natural-scroll false
I hope it helps, and if this is not what you are looking for, you can roll back the changes by entering:
gsettings set org.gnome.desktop.peripherals.mouse natural-scroll true
gsettings set org.gnome.desktop.peripherals.touchpad natural-scroll true
My personal favorite is:
gsettings set org.gnome.desktop.peripherals.mouse natural-scroll false
gsettings set org.gnome.desktop.peripherals.touchpad natural-scroll true

A couple of months ago I upgraded from Ubuntu 16.04 to 18.04 as one of many steps in attempting to fix my wireless drivers.
Ever since the upgrade, however, natural scrolling has been broken. Rather, it's been stuck on.
When I go to
Settings > Devices > Mouse & Touchpad
it doesn't matter if I setNatural Scrolling
to on or off, it's always on. When I two-finger scroll up, the page goes down. When I two-finger scroll down, the page goes up.What makes this even more confusing is that natural scrolling doesn't affect horizontal scrolling. So a two-finger scroll right will move the page right and a two-finger scroll left will move the page left. This discrepancy between vertical and horizontal behavior has made it impossible for me to just adapt and get used to the new mouse mechanics.
I tried uninstalling
xserver-xorg-input-synaptics
(per Ubuntu 17.10 natural scrolling) however this did not change anything (other than free up 180 MB of disk space)Minor Update
Uninstalling the Synaptics drivers may have had some affect - but not a positive one. I've started to notice that scrolling will randomly stop working entirely in certain apps or on certain web pages until I restart the app. Natural scrolling is still stuck on, but it goes from being annoying to being outright nonfunctional as the trackpad doesn't scroll at all after some time.
I'm reinstalling the Synaptics driver and we'll see if my scrolling remains consistent.

Admin almost 6 yearsYou installed synaptics instead of libinput. That's OK. In previous Ubuntu versions there was no GUI switch for libinput.

Pilot6 almost 6 yearsYou don't need Synaptics driver for 18.04. Libinput is used.
