Bug#868817: release-notes: Example emulate3buttons snippet should include option "scrollmethod" "none"

[Matthew Vernon <matthew@debian.org>]

Package: release-notes
Severity: normal

Hi,

Section 5.3.3. of the release notes (about the transition from evdev
to libinput) has an example of how to get the old emulate3buttons
behaviour (i.e. use click both buttons as middle-button). It should
also mention, though, that libinput is likely to leave middle-button
and drag as scroll up and down (because the default scroll method is
button, and the default button is 2). This means people who just
wanted a middle button will get the confusing behaviour that their
"middle" button clicks OK, but they can't click and drag with it.

I think this should either be documented, or the snippet adjusted to
add:
        Option "ScrollMethod" "none"

Thanks,

Matthew
