Horizontal scrolling is not "Austrailian"

Please describe your issue:

In Chrome OS settings I have set the touchpad to the "Austrailian" (aka "natural") setting.

After installing crouton, the crouton/xiwi windowed apps I run do not scroll horizontally the same way Chrome OS does.

Crouton/xiwi apps do obey that setting for vertical scrolling.

Please advise if there is a crouton config or anything I could try to get natural scrolling horizontally. Alternatively, if there's a different crouton install, target, etc. that should yield better results that would be helpful as well.

If known, describe the steps to reproduce the issue:

Chromebook model: Google Pixelbook
Crouton install: $ sudo sh ~/Downloads/crouton -t xiwi,touch

We only process the wheel messages we receive; see https://github.com/dnschneid/crouton/blob/master/host-ext/nacl_src/kiwi.cc#L610

I dunno if we have access to the australian scrolling setting to do anything smarter. @drinkcat?

I inserted the following as line 125 (right after the if of # Crouton-in-a-tab: Start fbserver and launch display) in /usr/local/bin/croutonxinitrc-wrapper inside the chroot:

xmodmap -e "pointer = 1 2 3 4 5 7 6"

This works for me for both windowed and full-desktop (KDE) apps. Scroll direction (both horizontal and vertical) remained consistent between ChromeOS and the xiwi apps even as I toggled between traditional/Australian scrolling.

The solution from @ibrado worked perfectly for me.

Is there something we can do to detect Austrailian and apply this automatically for people?

[ibrado]

Actually, it works for me either way (Australian or traditional), so perhaps this can be applied as a general patch. I haven't tested it in other desktop/X11 environments though. Which one are you using, btw?

[DavidFrahm]

I'm just using plain xiwi with the extension to run one app (WebStorm IDE) in a window.

My crouton install:

$ sudo sh ~/Downloads/crouton -t xiwi,touch

My app launch:

$ sudo enter-chroot xiwi webstorm
