nVidia has zero incentives to play open for linux, they release the binary blobs, next to zero docs and support, and you deal with it. The last nVidia card I bought was 20 years ago, and it was so bad for linux (low perf and freezes for the open drivers, manual re-install hell and pray on each kernel update for the binaries) that I switched to ATI. Since then, ATI or Intel always were decent with zero headaches.
Intel looks like they'll leave the dedicated GPU space, so it's a bit doubtful if the drivers will ever catch up.
I've seen several stories like this. Which is a shame since Intel offers the best value GPUs on the market.
I guess it's possible they'll still make workstation GPUs while skipping the consumer market.
