Welcome to the forum!
Please read the pertinent information in the two posts below. 
I didn’t use a tutorial video… I just did it manually… I went to hardware configuration and then I right clicked on a driver and installed … I only have integrated graphics card… So I now think it is unfixable… I am in the verse of installing manjaro xfce…
Probably vesa…
I still dont understand why people click random things.
(or why vesa isnt hidden in the GUI or something)
Its not difficult to recover … but if you are already reinstalling …
