Ubuntu – Natural Scrolling on Ubuntu Gnome isn’t working

There’s a way through dconf Editor; so:

1. open dconf Editor through the Dash;
2. go to org > gnome > settings-daemon > peripherals > touchpad;
3. check horiz-scroll-enabled, as you see in the screenshot.

Edit: Dconf Editor was pre-installed on 13.04, where I first faced the problem; but on 13.10 and 14.04 it’s easier to use gsettings, see Samuel Cavazos’s answer.

According with this answer, you can enable both two finger scrolling and edge scrolling using the following commands in terminal:

synclient VertEdgeScroll=1
synclient VertTwoFingerScroll=1

The problem is that these commands are not persistent after a system restart. To prevent this, let's put them to run at start up.

First, make a new small bash script called scrolling with the following code inside:

#!/bin/bash

synclient VertEdgeScroll=1
synclient VertTwoFingerScroll=1

Save it in your ~/bin directory, and don't forget to make it executable using the following command in terminal:

chmod +x ~/bin/scrolling

Second, search for Startup Applications in Dash, and open it:

Then add the script scrolling to run at startup:
