Natural Scrolling takes no effect in some places

[Xhacker Liu]

Natural Scrolling takes no effect in some places.
For example, in the Ubuntu Tweak Source Center, the scrolling direction is reversed.

Thanks for your report.

I can confirm this bug, and I found that it only work under GTK+2.0 Apps, It doesn't work under GTK+3.0 apps like Software Center.

I will try to research more about this.

[Xhacker Liu (xhacker)]

Seems the issue still exists.
(try somewhere like Ubuntu Tweak Source Center)

[Ding Zhou (tualatrix)]

Oops, except Ubuntu Tweak, everything is working.

Let's me see see.

[Xhacker Liu (xhacker)]

In fact, in some other places, e.g. nautilus, it not works too.

natural scroll is reversed in evince as well (ubuntu tweak 0.7.1-1)

[Nick M. (slimamericanhorn)]

disregard that previous comment, sorry

Not working also in update manager with Ubuntu Tweak 0.7.1.

Oh, and the horizontal scrolling works "unnaturally" too.

This needs to be handled upstream at GTK 3.4; I believe their implementation of 'smooth scrolling' ignores the traditional mechanisms for reversing scrolling direction (Xmodmap).

Too bad, I just upgraded from 10.04 -> 12.04 and stumbled upon this bug. Gtk3/Gnome3 is indeed ignoring my xmodmap settings.

Natural (vertical) scrolling is also ignored in Marlin (from Elementary) but I think that's their fault :)

I can confirm this bug is still relevant, at least on Ubuntu 12.10 on a Gazelle Professional laptop from System76 (has Ubuntu preinstalled).
