Linux

Check out Framework if you haven't already! https://frame.work/linux

They're designed to be upgraded and repaired over time so they're super modular. You can also save some money if you're not afraid to put it together yourself.

Lenovo is renowned for their excellent linux compatibility. I'm sure you'll get a bunch of proponents here saying the same.

BUT, oh boy. Don't get me started...

Too late. Having used various models of thinkpads in recent years, their inconsistent keyboard layouts will drive you absolutely insane. I swear, at this point they're just fucking with us.

I've got one in pieces somewhere, that has/had the ~ key next to the FN key on the bottom row! How the fuck are you supposed to use Linux if you're ~ key is down there? It's fucking stupid.

Not to mention their keys have a tendency to break off with just the mildest of fist slams.

AND the latest work-issued recent model is fucking with us again! It has the FN key ON THE LEFT SIDE of the Ctrl key on the left. Who does that? The Ctrl is always the left-most bottom key. Now, every time I fucking go to press Ctrl+something, I end up hitting FN instead.

Fucking morons! At this rate this laptop will also end up in pieces.

So, tldr; Stay the fuck away from Lenovo if you want to use Linux and not end up in prison for vehicular homicide.

Used Thinkpad from eBay is your best bet to start imo.

I'm a fan of Framework laptops. They have given people the option to upgrade several motherboards by Intel and released an AMD version to boot. I don't think there's ever been a manufacturer that offered three generations of motherboards on the same chassis. The swappable ports are kind of neat, you can choose which ones you want to use

The 13" is already on sale with a 16" coming later this year

I bought a DIY Edition Framework Laptop 13 with an i5 1240p for about $1050 after buying my RAM and SSD on their own. This is the best option if you're into modularity and upgradability and second only to buying used when it comes to environmental friendliness (in my opinion). Battery life isn't anything to write home about at least on 12th Intel though, supposedly 13th gen Intel CPUs do better

Otherwise, System76, Tuxedo Computers, and Laptop with Linux are probably good options if you want Linux pre-installed. All 3 of those take Clevo laptops and make them their own.

Starlabs also looks like an interesting option, but I believe the Starlite is the only option under $1000 USD. As far as I know, they're the only company that makes their own laptop chases from scratch for Linux.

I'm on my second Dell XPS 13 Developer laptop which comes with Ubuntu pre installed. I loved the first one but played too much Minecraft and wore out a couple of keys. I had it long enough that decent replacement keyboards were hard to find so I got a new laptop from the same line. I love the second one even more. My brother, also a Linux-using software professional, made the initial recommendation, so there is at least one other person who liked this line.

You got all the good infos already, but I'll stress:

1. Get Linux preinstalled from a reputable vendor. Linux works on most devices really; but when buying new, you don't want the hassle to even think about drivers.
2. If you cannot buy from a Linux-friendly vendor, buy an older model that's VERY popular with Linux users (like the stereotypical thinkpad). Again, most devices will work, but you don't want the hassle.
3. Intel everything just works out-of-the-box with Open Source drivers and is good enough for work. I'm not aware of the current state of AMD, nvidia drivers.
4. Choose a popular generic purpose distro. They are all good (enough) and should work out of the box. Popular for end users are Ubuntu (although hated by a vocal group) and related ones such Debian or PopOS; maybe Mint. I'd put Fedora/RedHat and Suse on the same level (but I wouldn't know since I settled on Debian/Ubuntu long ago). Then, Arch adresses a different clientele who wants to tinker with there system; not my choice if you want a computer that just works, but great community. Anything else probably has too small of a user group unless it's popular with your friends or line of work
5. Treat it like a Mac. It's different.

If you can you should try to savve up for a framework laptop

If your on a budget, an older Thinkpad is a good choice. I picked up a X220 with a charger and spare battery off of Craiglist a year ago for $60.

Ended up going with Coreboot with a SeaBIOS payload and Debian OS.

If you're thinking of getting one, i personally would recommend getting one from https://www.tuxedocomputers.com/. Extremely good quality and a really clean distro with Tuxedo OS 2 although you are able to install on it whatever you want.

I know you mentioned System76, but I thought an anecdote of the gazelle 15 I bought during covid would help.

It's the 2021 model with a 10th-gen i5, 16GB DDR4 RAM, a cheap 256 nvme SSD, and a GTX 1660ti for $1300. Very good laptop that I've used the hell out of since then. Has an excellent 120hz IPS panel (1080p) that's just buttery smooth, and using pop_os on it has been very stable, even with all their firmware updates including the switch to coreboot for their UEFI. Plays all the games I needed to when I was away from home, and the keyboard is one of the best I've typed on, on a laptop.

Now my only issue with it, is the shell, which was not entirely metal as I was led to believe. It's got some pretty cheap plastic for the bottom side that feels like it will crack if dropped even from a short height. I THINK this has been changed in newer models though, as they were using rebranded Clevo laptops for their chassis. Still, I hate that it's half nice brushed aluminum looking metal and half brittle plastic housing a VERY (at the time) expensive parts. It's the only flaw

Does this change my mind on buying System76? No, because I've seen their newer stuff and it's made leaps and bounds from my laptop in just a couple of years, and I absolutely plan on buying a beefier Oryx Pro or something on the future. They're excellent Linux machines

If you're looking for a cheap but solid laptop, you can get some pretty good deals on Dell Refurbished. Click on Laptops at the top, then look for the 50% off codes at the top of the page.

System 76 customer here. I just replaced my 2011 system 76 lemur with a new lemur. I have Ubuntu installed on both and have never tried pop os. I was very happy with that laptop and the company in general. It actually still runs okay. I did replace the battery after about 5 or 6 years. I'm thinking of trying out nixos on it.

My guilty reason for upgrading was I wanted to play dwarf fortress at more than 5 fps...

Thinkpad T480s if you wanna save money for another something but get a good screen version. To take it to 1000USD on refurb /2nd hand Thinkpad Carbon.

Youre in a Linux thread, these run Linux like a dream.

@PurrJPro You can't go wrong with @tuxedocomputers but it's gonna be hard to stay under 1000USD. Everything they have runs beautifully with linux and their support is far better than you'll find anywhere else. I've bought more laptops over the past 20 years than anyone probably should, and finally going with #TUXEDOComputers was worth the little extra I spent on it.

If you want to just buy some cheap laptop off the shelf, that's okay too, just do your homework first. Find out what hardware that exact part/model number has in it so you can know what sort of problems you may be dealing with later. I've bought at least 2 different models each of Sony, DELL, Acer, ASUS, HP, IBM, Lenovo, Apple, Compaq, 5~6 different off-brands I can't remember. Some work great with no hassle at all, some take loads of fiddling, and some have hardware that just doesn't work at all.

Framework all the way!

System76 is plenty great. Not cheap, though. Thinkpads also have never let me down
