So, I'm trying to get all my laptops up to using libinput because my newest one it just "works" correctly. However have a couple questions about configuring it:

1. On one of my laptops, it MOSTLY works. It has edge scroll enabled instead of 2 finger scroll. I want to disable edge scroll and enable 2 finger scroll (I know the hardware supports it as I was using it on Windows). This laptop I'm still using libinput, but I'd really like to get this fixed since the touchpad works REALLY well with libinput otherwise.

2. On MULTIPLE laptops, it almost works. Single & 2-finger tapping works, 2 finger scroll works, but 3-finger tapping doesn't. These I'm all using synaptics because it fully works. I've tried following the arch wiki for configuring libinput multiple times, but I've NEVER manged to get 3-fing tapping working with libinput on ANY of these. I can stay with Synaptics as it'll probably be quite some time before it's fully deprecated, but I'd PREFER to be able to use libinput since it's usually a bit more predictable in terms of actual touchpad movement, but not having midldle click is simply too big an issue to deal with.

So, does anyone know how to do these configurations, or have a link to a page that describes exactly how to configure them?

Thanks

I’m out and about with only my iPhone currently, but I recommend reading the man page first
The following command is useful to get device attributes reported
Attributes can be set on the fly or via options in an Xorg config file.

The Arch wiki page is a good reference as well.
https://wiki.archlinux.org/index.php/Libinput

YEah, read that page like 10 times now. As I said, nothing I've tried from that page has done anything to help. I've successfully broken the touchpad multiple times, but never managed to get something working that wasn't. I had initially assumed it was just setting the TappingButtonMap to lrm, but that didn't work. I've tried playing with ButtonMapping, but haven't had any success. Nothing else seems like it would affect it.

Now that I'm back in front of my Linux box, I realise the command should have been
From 'man libinput'...

The Xorg configuration option is specified like this...

Unfortunately (as the Arch wiki page) mentions, the "libinput driver has fewer options to customize touchpad behaviour to one's own taste, but far more programmatic logic to process multitouch events (e.g. palm detection as well). Hence, it makes sense to try the alternative, if you are experiencing problems on your hardware with one driver or the other."

This thread suggests that "3-finger tapping" is not possible currently with libinput...

If you feel that the required feature is missing, then a bug report is the best way forward.

It's definitely possible. 4 of my laptops have 3-finger tapping working and are using libinput. Not restricted to a single OS, as they are each running different one (q4os (Debian Stretch based), Arch, Gallium (Ubuntu 16.04 based), and Fedora 27).

AS far as the scrolling, I'm sorry to say that it was a fat fingering that was preventing that from working. I HAD actually updated the correct option, I had mistyped the line, however. I had looked at the line it seems 100 times, and never noticed until I copy/pasted directly from the man...THEN it worked.

I must have misunderstood your opening post where I understood that you couldn't get 3-finger tapping working...
You could compare the 'libinput-list-devices' output between the four that work (with libinput?) and the ones that don't.

That reads like progress.
