AMD is no problem. Only nvidea (of the big mainstream hardware manufacturers) does not supply Linux drivers.
In fact AMD will most likely make it easier than Intel if something doesn't work. Intel pretty mutch only thinks about Winows, so if there are driver problems, there are only windows drivers to download on their website (but there shouldn't be an problems in the first place anyway)
Where did you get that from? Intel officially supports their drivers on linux and has many engineers working on support for their products in the kernel and mesa.
It's rare that I see something this false on here, damn.
Nvidia does supply Linux drivers and they are 95% painless nowadays (still much worse than what is found in Mesa for Amd or Intel, but the bar is high).
Intel has excellent Linux support, better than AMD in some cases (think wifi chips). Anectdonally, I have had a bit of issues with my Amd laptop, and the flaws were all related to the integrated GPU!
Yeah I was pretty surprised. There are still some frustrations now and then but the Nvidia driver has gotten much closer to AMD lately. There's even an open driver being developed.
