I've been going through lots of pages trying to figure out how to enable two finger scroll with my touchpad. I tried setting evdev options but they don't work. I tried installing the Synaptics drivers but installation fails because of package dependencies. Has anyone firgured out how to approach this?

These are the outputs I'm getting:

Trying to install some of those dependencies manually wants to remove KDE among lots of other packages so I obviously didn't continue.

I did find a very similar question and with sheer luck this person has exactly the same 2-in-1 as I. Unfortunately I didn't find the solution there either.

Is it at all possible to install Synaptics drivers in KDE Neon? Or can I somehow enable two finger scrolling with the default evdev driver? Unfortunately KDE touch pad settings tell me there is no touchpad found so I can't fix it there either.

I used Opensuse Tumbleweed for a while and two finger scrolling worked just fine out of the box. I only switched to KDE Neon for stability issues and because of its Ubuntu base and better software support (deb seems to be more widely adopted by developers than rpm).
