Soon I will need a lightweight laptop with Linux for long-distance travel.
Up to 12 inches diagonal and up to 1.2 kg would be optimal. Do you have recommendations there, or you know sources of supply for the completely installed computer?
There are no laptops on which Linux is preinstalled (with good reason)
You would have to buy a normal laptop with 98% Windows on it and then install Linux.
What is the good reason? Because there's so much distros and everyone has their own preferences?
The most important thing you forgot, the budget.
Basically: Thinkpads work very well with Linux, but are also quite expensive if you want a new device. There are laptops with preinstalled Linux but I do not know any in 12 "format.
Because the average consumer has no desire to rumzuärgern with unfinished business and can't fall back on any deeper technical knowledge.
Well there would be synonymous distros that are a little more user-friendly. And anyway, the ottonormalverbraucher would anyway buy a laptop with linux.
I do not understand. Why are Thinkpads working very well with Linux? Did you install a special chip that accelerates Linux?
No, they just consistently use components that are fully supported by the Linux kernel. This does not mean, of course, that all other laptops have any problems with the Linux kernel, but experience shows that you are on the safe side, especially with ThinkPads.
Of course there are some, for example those of Tuxedo: https://www.tuxedocomputers.com/
But there are also other manufacturers.
I'm currently sitting on a 13-inch Lenovo with OpenSUSE. I bought myself refurbished two years ago in Kāṭhmāṇḍau, to just under 300 euro. Once in the store, we booted with the installation stick, and when the installation menu came, I bought it and then installed it for two nights.
This is my fourth laptop, no one has caused me serious trouble installing or operating, at least not from the software side (but I had a weird one from a Chinese company called Hasee, which did not install any distribution except openSUSE, why always).
The fear of self-installation I think frankly exaggerated. Hardly ever gets devices with pre-installed Linux, and if that's the wrong distribution (Linpus, scary!).
Why are Thinkpads working very well with Linux?
Because these are very widespread in the professional field, ie in companies, authorities and organizations (just like Dell) and therefore more developers (who work there mostly) have access to such devices.
I own three Thinkpads here with Arch or openSUSE, but nothing up to date and certainly not under 14 "because of my bad eyesight.
If I had the necessary "small change" I would rather a https://slimbook.es/en/ or a https://www.tuxedocomputers.com/ and "for the sake of" Ixsoft want to aben because they are optimized and some have also built open hardware.

That's not true at all. Please investigate that again correctly.
And while you're at it would be nice if you call these "good reasons" and enough could prove with links.
You would have to buy a normal laptop […] and then install Linux.
What would be synonymous with the vast majority of distributions synonymous no problem, as you are through with 7 steps through and has within 30 minutes a ready-to-use operating system on which you do not have to insert later driver CDs!
