Windows can’t read your linux partitions, it doesn’t support them, so it’s almost impossible for it to damage your installation. It used to be that it could mess with the bootloader, but since UEFI got implemented, that’ become less likely.
What does it do when you boot into normal mode? Does it get to the login screen or not? Do you see error messages?

If you get to login but no further, it could be a problem with your user, like a bad shell setting, since rescue mode logs you in as root usually (I’m not very familiar with debian/ubuntu based distros), otherwise it could be you installed/updated/removed the wrong package(s), unfortunately as far as I’m aware apt doesn’t have history rollback capabilities, so undoing that is going to be difficult.

This is an unpopular opinion, but when you’re still inexperienced with linux, the quickest way to fix your system is just reinstalling. Back up your whole home dir beforehand and you’ll just have to drop it back in place to get all your data and settings back. If you have more than one user you may want to be careful with the UID, you may have to chown -R the whole directory.

No

Cazzate

YES SIR!

the whole 3 or 4 of them?

Watch out for the slippery slope!

I think you better fix it, what if ChairmanMeow searches for Johnny Pneumonic?

Lol Johnny Pneumonic

For me it’s the opposite, generic names make searching for issues on the web stupidly difficult.

No one has problems figuring out that Dolphin is the file explorer, and if you search for “file” in the KDE menu, it returns Dolphin as a result.

eh, it’s not all root, essentially just the binaries. /etc and /var are RW

did three major version upgrades so far and they have been flawless.

To be fair, I’ve upgraded normal Fedora for like… 8-10 versions in a row maybe, and never had a problem

Holy shit can you guys read the article please? It’s an existing standard and a dedicated keycode

Yeah but if we’re talking about Amazon, we’re not talking about groceries

It’s less green tho. Everybody going to the store vs. one vehicle going door to door.

Yeah, USBC and HDMI cables are a crapshoot. My phone came with a fast charger and it always only worked with the cable that came with it, now it also works with Arzopa’s one.

I have a non-touch 1080p one I got for work, 80€, brand is Arzopa. Works fine, uses USBC for power and video which is quite cool since it’s a single cable, it has 2 usbc ports, I guess if you have a lower power output on your PC’s port you can add a power brick, they’re also both functional so if one breaks you still have the other one. It also has a mini HDMI port.
It came with three cables: usbc-usbc, usbc-usbc, miniHDMI-HDMI, all three good quality.
It has folder case but carrying it in my backpack damaged it anyway, I have a couple bright spots, but they’re rarely visibile.

Wireguard is quite magic itself

If you take charge of maintaining this system, maybe it would be easier to install HA supervised in a docker container and have another container for wireguard+syncthing.

A pi5 with 8gb should be enough unless your parents’ HA is an hypertrophic installation with hundreds of devices.

I had an embedded Celeron server, passively cooled with 1 hard drive and 2 SSD which used to idle in the range you mentioned, measured at the outlet… It had a random PSU that came with the mini case it was in.
Realistically, how low do you aim to go? Disks for example add a lot of wattage.

I’m sure he doesn’t know your family as well as you do, but as for jellyfin, that’s exactly what you do, open it in a browser and stream, I don’t understand what’s your objection to that
