I'd like to get the raw multitouch data from my touchpad in order to.

I've tried using libevdev but my success was limited and I couldn't do what I wanted. I found out about libinput which might be more abstracted, and found out how to use it to automatically get the gestures (for example using libinput-debug-events) but I find them limited and would like to get the raw input (with each finger's movement).

Is there any way to do this with libinput, or not?

I couldn't find any helpful documentation: I found this one but couldn't find any example or route to follow. Actually, I think that I could make myself a way through my problems if I understood how to use these functions, but it's far from clear, and I'm getting in a lot of trouble installing libinput itself (for example, commands like libinput debug-gui aren't recognized by my system).

Any help is appreciated.

Don't know if this helps or not, but on my distro (Ubuntu) I installed libinput-tools.

sudo libinput debug-gui

Also gives me an error:

debug-gui is not a libinput command or not installed.

However, 

sudo libinput debug-events

will print out events in the terminal just fine.

    For me it doesn't log raw data but rather high-level events, without the exact coordinates for each finger. – m93a Jan 06 '19 at 15:52
