I like running Linux on my Lenovo Ideapad. It wasn't expensive and has everything I want, including easily running Linux.

The only thing is it's not a popular laptop so it doesn't have accessories, like cases or whatever.

I was always happy with everything I got from Lenovo (mostly ThinkPads but also IdeaPad), both cheap ones, used and new ones, always worked without any problems.

I'm ok with the XPS 13 from Dell but I had some problems, they needed to replace the motherboard and when you hold it it bends a bit and does register a click on the touchpad.

I hated my Tuxedo laptop, very expensive and very bad quality, had to send it in to repair twice and after a year I gave up on it because it was so broken and bought a used ThinkPad.

Thinkpads, macs and dells are what I use.

They’re cheap and have lots of spare parts lying around.

I cannot say that I have done extensive testing, but the Acer Swift 315-51G and Gigabyte Aero WV8 that I have both worked fine with Linux with zero prior research on my part. No issues with any drivers, even the SD card readers, although I have not checked the fingerprint sensor on the Acer. Maybe I have just been lucky.

Both have hybrid Nvidia graphics, though, and 10-series and prior hybrid graphics especially, as I understand, have issues with high idle power usage unless you manually disable the dGPU when not gaming, which I had to do using envycontrol and nearly doubled my battery life on both. I might avoid hybrid dGPUs and especially older ones unless you need that.

Used laptop-wise, I agree with others that a used business laptop like a Dell would probably be your best bet.

I am gonna get a shit ton of hate for this... MacBook air. Yes, I am on a Linux sublemmy, saying that I like macs but the hardware is just too good to justify spending money on a x86 laptop.

Though, those new snapdragon X Elite laptops do look pretty spicy... Too bad they weren't yet announced when I bought my Mac.
