I get it, I got so frustrated with Linux on laptops* -- one literally set my kitchen table on fire and melted the glass when the fan drivers didn't work -- but, to be fair, this thread IS "A good Linux laptop below 1000 euro".

I don't think there is going to be a perfect Linux on a laptop experience anywhere. The manufacturer-supported Linux variants might be better (dunno, never tried), or a Chromebook, but short of that it's mostly shared components by a few OEMs anyhow.

*Recently bought a Mac, reluctantly, after 30 years of Windows on the desktop and decades of Linux on the server. It's a godsend not having to deal with WSL/Multipass/Docker/Lando etc. just to do some quick dev work AND never having to worry about drivers. The UI is fine, if a bit keyboard-unfriendly compared to Linux and Windows. I don't like Apple as an evil monopolist company, but macOS is admittedly pretty darned nice.

The touchpad doesn't work properly on windows either, and the CPU draws a lot of wattage no matter what OS you use. I would bet on most people having a similar experience between the X1 Extreme and the X1 Carbon, but sure, maybe the design has improved too.

The fact of the matter is that the X1 Extreme suffers the same disease as many other Intel ultrabooks. It doesn't have sufficient heat dissipation for the processor, or battery capacity to service its power hunger. And it comes with synaptics touch pad.
