Natural scrolling

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
