I don't think there has been a developer edition with Linux for any XPS models in a while, so the likely answer to your first question is no.

And similarly, XPS models haven't had official LInux support in a while -- so that answer is also likely, no.

There isn't a way to order a system without an OS, and there is no separate charge for Windows.  With recent XPS models, Windows 11 has been the only OS supported.

There are companies that will sell notebooks without an OS -- Framework does, and many boutique gaming assemblers will.  Most of the large OEMs like Dell, HP, etc. will not.

That is not completely true, the XPS 13 Plus 2022, and I believe the 2023 version as well, is indeed Ubuntu certified and can/could be delivered by Dell with Ubuntu preinstalled. At least in Germany, see https://www.dell.com/de-de/shop/laptops/xps-13-plus-laptop/spd/xps-13-9320-laptop (Operating system Ubuntu® 20.04 LTS (64 Bit)). Most (all ?) Lenovo Thinkpads are Linux certified and may be a good alternative as this years models from Dell doesn't seem to support Linux unfortunately. At least for now...

@ejn63​ My last one was purchased Mar 29, 2023, less than a year ago.

Any updates on this question? I've been waiting for a month to see if ubuntu gets available in the website.

I guess they will give an answer when there are back in stock

I'm also very interested if a developer edition gets out for the XPS 13

I'm also waiting for this. I want to buy a new laptop and not sure if I should wait, or just go with the Lenovo Carbon X1

The 2024 editions is like they took everything people hated with Apple (touchbar, capacitive keyboard, no jacks etc) and whom even Apple took back. So sad to see, I had 3 Dell Xps over the years, all with Ubuntu preinstalled, but the 2022 edition might have been my last. Why not listen to the developers/customers Dell?

I wish to buy XPS 13 without Windows in Switzerland. Not available, all links dead

Not currently available -- Windows 11 only.  There's a new XPS 13 (9340 Intel and 9345 ARM/Snapdragon) coming soon.  Whether it'll be available other than with Windows remains to be seen.
