have a look on the web, then :"Your card is only supported by the 340 legacy drivers series, which is only available up to buster."

Damn right it's disappointing like you I've spent major time trying to get the Nvidia proprietary driver to work.
Don't know who to hold at fault on this.
I'm leaning towards the developers.
==> people buy a computer regarding main perfs and especially the price, not the graphic gpu manufacturerThe moral of the story is: "don't buy Nvidia"
