From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I don't think you're right on this. When DELL is branding a laptop as "linux supported", then the hardware normally works out of the box with at the very least, Ubuntu (and probably by most other distros too). If you're seeing hardware incompatibilities, it's probably because the Linux kernel itself might have dropped some of the older hardware drivers from its list of support. I'm writing this on a DELL Latitude 5480 from 2017, and I have installed the latest ubuntu without any hardware issue whatsoever. Everything's just supported out of the box. No special image from DELL was ever required. So if you're seeing your hardware stop working, you should look if DELL provided closed source drivers or firmware for your laptop's hardware. If that's the case, then you didn't have a "linux supported" laptop, you had a laptop with specifically-added Linux support after the fact. I wouldn't have bought that in the first place.
You have this view because your hardware is from an era where fingerprint reader largely weren't a thing and webcams were connected via internal usb. The issue is not that the Linux kernel drops anything (between you and op, you're the one with the old hardware). The issue is, that fingerprint readers became a commodity without ever gaining universal driver support, and shengians like Intel pushing its stupid IPU6 webcam stuff without paving the way upstream beforehand
In that case, the solution is to buy hardware that is linux-certified.
So not Dell, apparently. OP has a valid point. Dell claims to support Linux but in practice doesn’t.
Specifically the shitty IPU6 situation is on Intel, and is invariant to any laptop manufacturers. I also have a Thinkpad X1 with that issue. So for that the situation that one manufacturer would support it properly (i.e. upstream) and others don't can't exist, as soon as anybody puts it upstream it works for everybody. Thankfully there's some progress (search for libcamera) and in the not too distant future it should work ootb. For fingerprint readers it is a different story though, as there are many different ones, so that one is on Dell indeed
