I have misread the meaning of only in your sentence. Only for gaming and nothing else, almost 0%.

How many people realistically only uses their desktop PC for gaming […].

The majority? Not everyone can or wants to afford 10 gaming gadgets just to play the same games on different devices.

what’s the benefit of using a “gaming” distro

There are some benefits. (I haven’t and don’t plan on watching the video, so I don’t know which they used.) CachyOS has some optimized kernels that help squeeze out more performance out of latency sensitive games. It is not earth-shattering, but there are measurable differences. One personal example was CS2. It ran fine on Fedora 42, but on Cachy there was noticeable less stutter when there was a lot of action.

I can second CachyOS. The last time it caused me headaches was kinda my own fault. VirtualBox needed some dependencies which I didn’t read thru, then it installed an older kernel version for some god damn reason and I lost my ethernet driver. Took me quite some time to figure it out, but as I said, not Cachy’s fault!

Tnx, I’ll give this one a shot.

I understand fully. When I stumbled upon it, I thought it was just their RPi clone with more powerful hardware (it’s even GPIO compatible). At that point I didn’t have much time to reaseach to what extent it was supported and just assumed at least some general functionallity since it came with Ubuntu and not some random embeded OS. I should have known better, but I do now.
What drew me to it was not the AI stuff, but rather the premise of a decent CPU and GPU package in a small form factor, ideal as an HTPC. And that it was just 7€. You can’t buy anything for that much money, even less a whole ass PC.

They have one official image for the Nano. All others aren’t supported and cause issues unless you hold some packages (which is the method I tried to get 20.04 working). HW acceleration still won’t work.

I am looking for something beyond the official docs that would help.
