how many things do I have to read

Well unfortunately, when using Arch, you will, at some point end up requiring to read a lot of something.

If that makes you hesitate, but you still feel like giving it a try, I'd say one good way is, install Arch using the Arch ISO method and go to https://wiki.archlinux.org/title/Installation_guide and read that once before and then, while installing.

• it is very well simplified (simplified by explanation, not by omission)
• it has handy links for terminology you will find in there, so you won't have to go around finding stuff all the time
• open the page on another device, that you like reading on
  • read it like you are trying to understand it and not like instructions
• while reading/installing it, if you realise you can't keep doing that, you have your answer
• if you managed to install it before getting frustrated at the Wiki, well, know that most Arch wiki pages you will look at, are as good or better than that and you can consider this as another distro you might use.

Arch is not the most widely supported distro (as in supported by the creators of programs). You will see it supported most by some of the more indie open source programs, but beyond that, Debian and Ubuntu are more likely to be explicitly supported.

Arch definitely requires you to read. It's a distro for those who want to assume greater amount of choice and freedom in their system. If you prefer an out of the box experience, try another distro.

You don't want Arch then. I'm sure other people will chime in with recommendations. I'm hesitant to make desktop recommendations because I mostly use Linux on the server, and I've never used an atomic distro or similar. But you probably want something mainstream, stable, and well-supported like Fedora.

The first time I setup Arch from scratch (no archinstall) it took me about 7 hours to get a working desktop environment. A lot of that was figuring what specifics I wanted, like boot loader and desktop environment. If you aren't already familiar with Linux architecture, the kernel, and basic terminal commands, you will be spending a lot of time on the Arch wiki. If you do already have a decent understanding of these concepts, then you will also spend a lot of time on Arch wiki.

Honestly, based on this response from you, Arch isn't this distro for you. It's work to setup, it's work to configure, and it's work to maintain. I jumped straight in myself with basically no Linux experience but about a decade of experience as a sys admin and power user for Windows. It's been a couple of years and I have no desire to even branch out because I enjoy the tinkering and resources.

I have an Nvidia GPU and the first 6 months I had issues, but there have significant improvements and now I almost never have any GPU related.

An example of needing to fiddle with things, I couldn't get audio to pass through my HDMI the other day when hooking my laptop up to a TV. I had to install a couple missing packages and then I was able to see the HDMI option in my sound settings, so then I could sell that as my output. Arch won't ever tell you what you need, it just won't work, so you have to read and figure it out yourself. Fortunately, the community is huge and the Arch wiki is fantastic. There are some shitty neck beards that like to gate keep, but ignore them and your experience will be better.

I use (atomic) fedora and I don't have to deal with drivers or anything system related. Among other good distros, I can highly recommend that for a set it and forgrt it system.
