I just installed Kubuntu 19.10 on this machine. Most is working out of the box, even Wifi, but there is an issue with the touchpad. It works only partially, I cannot choose by tapping (highlighting a word, f.e.) and scrolling only works with 2 fingers. F6 activates the touchpad, it is activated.

My kernel: linux 5.3.0-19-generic

$ xinput list

⎡ Virtual core pointer                          id=2    [master pointer  (3)]

⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]

    ↳ AT Translated Set 2 keyboard              id=11   [slave  keyboard (3)]

I've searched on the internet and found that I am not the only one, but it is strange, some people say they have to make kernel compilations and some people say that with a newer kernel it worked perfectly.

Here is some more information:
