Well, NixOS is pretty easy to install using their graphical installer and it has one of the largest package repositories. It has basically everything you could need.

I installed hacky ChromeOS to my grandma's laptop a few years ago. She never had issues with the OS itself, rather hardware issues. It's easy to learn and ChromeOS is literally just a web browser, it's not even useful for anything else. Though I would recommend you install something like Fedora Silverblue, Kinoite, or a distro from UniversalBlue instead. Container based distros are secure and hard to break.

I just read more about this, the Hungarian government was questioned about this and denied that any agreement was made. They said "VSquare is spreading fake news", but Viktor Orbán or the police wouldn't answer to any questions about the cameras, writes telex.hu in this article (in Hungarian)

I use an RTX 2060 on Fedora and it work very well. Initial setup is not that hard either, just look for instructions in the Fedora docs. And it works mostly perfect on Wayland, but you need to update through GNOME software so the kernel builds the NVIDIA akmod package. Do note though that updating takes longer this way.

That's what the cameras are for. And from the previous track record of the Hungarian government, they will not do anything about this even if the people protest or resist. See what happened to the teachers. They only got a small raise not long ago because there are upcoming elections. If this happens I'm just gonna move to Austria I guess ¯_(ツ)_/¯
