Natural scrolling [SOLVED]

Hi amm,

I'm no expert and so I'm sure there are better/easier/more efficient ways and I really don't even know if this will work for you. But here it is. A couple of versions ago I had an issue with getting Tap-to-click working. I did some rudimentary search and found xinput. So here's what I did to get the tap working. I suspect the scrolling can be done too. It's not a small program so if someone has a better idea you might want to go that way. Anyway, here it is:


Enable “tap to click” on TouchPad:
>install xinput: sudo apt install xinput
>list the devices to find pointer: xinput --list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ VGA Webcam: VGA Webcam id=10 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]
↳ Acer WMI hotkeys id=13 [slave keyboard (3)]

[note the ID number, 12]
>list the properties of the pointer: xinput --list-props 12
Device 'SynPS/2 Synaptics TouchPad':

libinput Tapping Drag Enabled (279): 1
[there are a bunch more. note the property, 277]
>enable tapping: xinput --set-prop 12 277

Bumping this with content from the old forum as I've just done this on Bodhi 6 and confirmed it works:

First (as root) created an empty directory /etc/X11/xorg.conf.d

In that directory, 40-libinput.conf with these contents:

Section "InputClass"
Identifier "libinput touchpad catchall"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
Option "Tapping" "on"
Option "TappingButtonMap" "lmr"
Option "ScrollMethod" "edge"
Option "NaturalScrolling" "on"
EndSection

Note that before this change, both two finger and edge scrolling were active on my touchpad, but afterwards only edge scrolling is. That's fine with me. The TappingButtonMap option "lmr" sets one finger tap to left click, two finger tap to middle click and three finger tap to right click. It's possible to use other combinations, like "lrm".

My understanding is that this is the preferred method for systems using libinput, as Bodhi is.

What about:
check <settings><settings panel><input><mouse><touchpad><scrolling><natural scrolling> (in "scrolling" section, after also checking "Enable Devices Extra")
does to trick for me (bodhi:6.1.0 / moksha:0.3.4)

context: just installed bodhi on my 2010 macbookpro and tuning it to my own (mac-biased) comfort.
