Universal natural scrolling in Xubuntu 16.04
Using Xubuntu 16.04 with natural scrolling enabling in Settings > Mouse and Touchpad > Reverse scroll direction leaves some apps with natural scrolling and some not. It’s extremely confusing and frustrating and non-intuitive.
To get natural scrolling to work consistently across all apps, uncheck the box in the settings and instead enable natural scrolling in X11:
sudoedit /usr/share/X11/xorg.conf.d/50-synaptics.conf
add the lines in the Section “InputClass” Identifier “touchpad catchall”
Option "VertScrollDelta" "-111"
Option "HorizScrollDelta" "-111"
Reboot and natural scrolling will be applied consistently.
