No keyboard with Microsoft surface Pro 6

[fanfan7110]

Very very motivated to test this OS (It's a genius idea, that said), so I installed it on a surface pro 6. The system boots but the keyboard is non-existent. No functional key, nothing that allows you to enter the slightest character.
It's a strange thing, since the surface pro 6 is 100% recognized by linux distributions.
Is there a way to solve this keyboard problem?

I also think that the screen is not recognized correctly, it is a 2736 x 1824 screen (267 PPI), and the characters that appear on the screen are so tiny that you have to take magnifying glasses to read them (which I did by the way) :)
The graphics card is an Intel® 620 Graphics.
