This may be a controversial inclusion, and it’s based on my relatively unsophisticated understanding of Linux. I believe the reason casual computer users hate Linux (generalizing here) is that “Linux” is not one thing.

Commercial operating systems are monoliths. Windows 11 is Windows 11. macOS is macOS. Apart from a few surface-level settings, all instances of them are the same. If you know how to use that operating system, you can go to almost any computer running that OS and start using it, just like you use the one you have at home.

“Linux” is entirely modular. There’s no single thing called “Linux.” You can pick and choose each component to build up your own customized OS from the ground up, and distros take advantage of this. I know just within my household, I have three Linux systems, and casual usage varies wildly across the three. One is a SteamDeck, which is a different kind of thing, but if I just take the two computers as an example, on one, you have an application menu in the top left where the other has an application menu in the bottom left. Also, those menus look completely different. That alone is enough to frustrate a casual user. Now take the fact that they each have different settings panels, different bundled apps, etc. and you have a recipe for making users always feel lost when moving from one system to another.

I don’t think this means you need to teach how to use every available desktop environment, window manager, or sound settings panel, but I do think it would be useful to introduce this concept as part of your curriculum. The sad part is that I think a lot of your audience will tune out at this point because they never had to know that on the commercials OSes, but I think it’s important to be forthcoming about it rather than having your audience blindsided by it.

I’m on a much weirder setup than you’re proposing — Bazzite Linux with a Pico 4 connected wirelessly via ALVR — and it mostly just works. I had to jump through a few hoops to get everything working to start, mostly related to tweaking wireless and audio configuration, but these are things I doubt you’ll encounter at all with an Index. I haven’t tried a game yet that doesn’t work. I mostly just care about Beat Saber and a couple of others, but they’re all working well. I’ve even bought a few new games since switching to Linux, and I can’t recall any I’ve tried that don’t work, out of maybe a dozen or so total I’ve tried. I suspect you’ll have a much smoother experience with the Index.

I’ve tried a few of these, and I’ve never found one that doesn’t feel like I’m inviting a sales rep to live on my home server. They’re technically open source, but it’s obvious their primary purpose in this form is to upsell you. I understand it, but it’s just not what I want so I’ve ended up getting rid of each one after tinkering with them for a while.

I guess the same could be said for n8n, but I find it more tolerable. I have set up a Valkey instance though and use it for persistent storage through n8n’s Redis support. That works well enough for my fairly limited use case.

My brother used to work for an SEO company. They charged clients to have their web sites on directories which would improve their Google pagerank… until Google updated the algorithm to penalize sites listed in these directories. The company quickly pivoted to charging the same clients to have them removed from the directories they had just charged them to be listed in.
