Why do all these Linux laptops use Nvidia GPUs?
Because they are just rebranding oem devices
Then why isn't there a single one of them that picks an AMD OEM device to rebrand? Why sell a Linux gaming laptop at all if the key piece of hardware that makes it a gaming laptop is one with infamously bad Linux driver support?
Aren't any AMD based ones? Seems to be very few laptops with AMD gfx overall.
I am very happy with my RX6800 based Asus Zephyrus G14 laptop :)
My RX6700 based 2022 is a beast. I think Valve did an amazing job with the AMD based Steam deck leveraging Linux as well! You can hook up the little handheld to a monitor or a TV and still have a blast with nearly all of your existing Steam library for not much money.
Few, yes, but not zero. Unless you want one with Linux on it from the factory, then it's zero.
Yes and it sucks, I would love one
AFAIK there are no OEMs that build AMD dGPU-equipped laptops. Most "small brand" and Linux-first laptop manufacturers actually sell rebadged Tongfang or Clevo laptops, and 99% of their products are Intel anyway. AMD CPUs are often only found in "gaming" laptops with nVidia dGPUs.
That's why I've put a deposit on a Framework 16. Zen 4 CPU, optional RDNA3 dGPU module, upgradable and repairable. They're not preinstalling Linux like Tuxedo or Slimbook, but they're at least Linux-friendly.
Framework isn't available where I am yet unfortunately.
