For what it’s worth, the multi-user experience in my case has been pretty seamless. Here’s my setup if it helps anyone:

My roommate and I both have separate steam accounts (it sounds like you may be looking for a ‘child’ account or something like that, those may be a thing but I’m unfortunately completely unfamiliar with that, so ymmv if you use that).
We set up family sharing between us to access each other’s games, but did that I think entirely on a computer via that steam client. No pins or anything were necessary iirc, just a slightly convoluted sequence of logging in and out of steam on the same computer and clicking the needed ‘family sharing’ buttons.

Then I set up the deck with my account, logged out, and had my roommate log in. There’s an option somewhere to start the steam deck at the account select screen every time it turns on rather than automatically logging in to the last used account.

It sounds like most of the difficulty is coming from the family sharing setup. Like I said, I’m not knowledgeable on if steam has ‘child’ accounts that can be linked to other accounts, if so it’s possible that none of what my process was like applies.

Hopefully that’s at least somewhat helpful

Rankine gang rise up

If it started: 0.999… = 1 - lim(1/n) then maybe we can talk, but I have no idea where 0.999… = 1 - lim(1 - 1/n) comes from, that’s just incorrect

“I thought that by stating that I would not tell lies, that I would be giving you more accurate information”

If you just believe in yourself enough, you can make anything you say true!

It’s kinda cool (to me at least lol) how literal the terms “additive” and “subtractive” for color mixing are. With additive mixing (such as on a computer screen), you start with black and add the primary colors (RGB) in different combinations. If you add all of them you get white.

Subtractive mixing (like pigments) starts from white and “subtracts” those same RGB colors. You can think of cyan, magenta, and yellow as “minus red”, “minus green”, and “minus blue” respectively, since that’s which wavelengths thise pigments absorb. So mixing cyan and magenta for instance gives you “white (RGB) minus red minus green”, which leaves only blue.

Just to clarify, with pigments (subtractive color mixing) the primary colors are in reality cyan, magenta, and yellow, which is why printers use CMY (and K, which is black). Blue and red are kinda close to cyan and magenta though, so those are sometimes stated as the primary colors along with yellow even though that’s not exact

Firefox with uBlock Origin has been working well for me, for ads at least. I haven’t looked too much into blocking trackers but I think Firefox has some ability to do that

For me it was pretty gradual. In my university research a couple years ago I needed to work with the university’s supercomputer running RHEL, so I got some exposure there. At some point I put Mint on my laptop, keeping Windows on my desktop “in case I needed to do any real work”, then about a year ago I put linux* on my desktop as well. I do still have a Windows dual-boot just in case there’s some weird software I need to use, but I haven’t touched it more than once or twice since. I switched partially out of curiosity, but largely as part of an effort to de-google and de-microsoft my stuff so I’m more in control.

*distro-hopped a bit, but now am settled on EndeavourOS

I was surprised at how much you needed the terminal, but also how easy it was to use the terminal after a bit of practice. I prefer it to GUIs for a lot of things now (like git). Also, installing software from a package manager rather than going to a website and downloading it. I didn’t like that at first, but I love that concept so much more now, since I can just sudo apt upgrade and everything is up-to-date (no downloading the new version after an update).

I’m now to the point that when I do need to use a windows machine for some reason, it takes me a second to remember how things work. It’s kinda a weird feeling tbh haha
