Ubuntu GNOME 16.10 - unable to enable vertical scroll using side of touchpad - Ask Ubuntu


i upgraded ubuntu gnome 16.10 16.04. have hp laptop touchpad. previously scroll using right hand edge of touchpad, no longer. can use two-finger scroll, , don't it, tends not work well.

i tried similar instructions this answer , this 1 too, "touchpad" option missing in dconf-editor under following tree:

org > gnome > settings-daemon > peripherals > touchpad

i have installed gnome-tweak-tool gnome 3.20 (using these instructions), has no options available either.

any ideas how scrolling using edge of touchpad?

update 1:

i looked under 

org > gnome > desktop > peripherals > touchpad

and settings available. scrolling parameter set edge-scrolling (see image below), not seem work.

enter image description here

update 2: created new user. because have fresh settings , show settings may corrupt. new user has same issue.

libinput on x11 workaround. taken directly ask.fedoraproject.org. made work ubuntu gnome.

there workaround libinpunt on x11:

1) determine id of touchpad, me synps/2 synaptics touchpad id of 11:

xinput list

2) create desktop file in ~/.local/share/applications named edge-scroll-workaround.desktop. creates edge-scroll-workaround application.

vim ~/.local/share/applications/edge-scroll-workaround.desktop

3) place here code in edge-scroll-workaround.desktop file:

[desktop entry] name=edge scroll workaround exec=/usr/bin/xinput set-prop **id of touchpad** "libinput scroll method enabled" 0, 1, 0 type=application

4) in tweak tool (available in gnome-tweak-tool package) go startup applications, click on + , in list find edge scroll workaround.

5) run edge-scroll-workaround.desktop, clicking super key , typing edge- , application should appear. logout/login or restart , that's it.
