one problem imo is that in nvidias view, their “linux drivers” is just CUDA, since that’s the majority of the market share, and those systems are mostly headless compute nodes anyway the desktop experience might not be worth supporting

can’t speak to lenovo, but i’ve had very mixed results with Dell. it certainly isn’t as smooth as system76 or the old (pre lenovo) think pads but they’re workable. the 13in dell models are better supported then the 15in in my experience
