Thanks for your comments! Enabling 2-finger scroll did end up in crash
for me previously, but it's fixed in git already. I did enable it with
$ xinput set-prop "SynPS/2 Synaptics TouchPad" "libinput Scroll Method
Enabled" 1 0 0
Well, can't say I'm a fan. It's possible I haven't got used to it yet,
but for me it's not very comfortable because when I'm trying to scroll
with 2 fingers, the cursor also starts moving at the beginning, so if
e.g. I'm trying to scroll something small, or if my cursor is simply at
the top of a scrollable widget — it can quit out of scrollable zone. And
even when it starts working, it's sometimes stops scrolling and cursor
I dunno, it might have something to do with my touchpad being "wobbly"…
Either way, side scrolling definitely have no such point of failure,
it's always reliable.
