I just did that on my own laptop, trying to figure out why it was running like crap. Turns out I set it to quiet mode instead of cool, so it underclocked instead of running the fan

I bought a new one recently. Apparently they’re doing a subscription thing now, so look closely at which model you’re buying. But other than that, it works just the same as my old one.

Yup, it works great. I actually did it myself when migrating from a centos to debian host. Worked first try, no issues (except one thing that was already broken but I didn’t know because I hadn’t accessed it recently). Containers are great for this.

This. Cloud-init, or autoinstall for Ubuntu, to get the install done, then use ansible for anything more.

Bind mounts. I’ve never bothered to figure out named volumes, since I often work with the contents outside Docker. Then I just back up the whole proxmox VM. (Yes I’m aware proxmox supports containers, no I don’t plan to convert, that’s more time and effort for no meaningful gain to me.)

You can restore that backup to a new VM. I just make sure it boots and I can access the files. Turn off networking before you boot it so that it doesn’t cause conflicts.

Does it work if you unplug and replug? If you hit a button other than power does it wake up, or does it say “no signal” or something? Does the laptop see it? Anything in any log? Can you force a redetection from the laptop?

The DJ is the artist. Each set is an album with one track. What’s broken about that?

You’ll need to check the logs for your display manager, probably kdm if you’re using KDE.

Jellyfin should be fine. Why do you say it breaks it?

On Lenovo it’s usually the delete key, I think. You should check the manual. It should also be an entry in the boot options list.

You might also try a reset, but it would also be helpful if you shared the “few rolling lines of text”.

How little ram and swap do you have that this is a problem?

You might just use ulimit: https://unix.stackexchange.com/a/746762/90708

I feel like there’s a better way to do this, unless you’re intentionally trying to run out of RAM.

In whatever centos uses for a prompt, it says “press tab for echo”, and it works. You’ll need to provide more info about your environment if you don’t have that option.

Yes, you can convert RAID1 to 10. At least in theory, your controller has to support it. Check the system documentation. TrueNAS ought to.

But gradual upgrades in general are rarely supported. The recommendation is always to do a complete array replacement.

Don’t put important stuff in /tmp. Put it in /opt or something.

Yeah. For a small shop, it won’t help. Just show up and be willing to work and learn. Save that money.

If you use the ISP one, you’ll rapidly find you can’t configure it to do what you want. Run your own, lock it down, and keep it up to date.

The apps you list need decent gpu and gpu doesn’t virtualize well.

That’s not really true any more. To actually get it working, especially sharing a GPU between multiple VMs, is finicky, especially if you’re not using the very narrow supported configuration and expensive enterprise hypervisor features. But it is possible, and you can find plenty of articles from people who have gotten it working.

But I still wouldn’t recommend it. I’d give one whole GPU to one VM with PCI passthrough, and let multiple users remote in. Hopefully the apps support that.

Depends on how you want to define “securely”. A sufficiently motivated attacker could attack the remaining encrypted data, either through brute force or exploiting a weakness in the algorithm.

Students, as in you’re a teacher? Talk with your school’s IT department first.

No idea, you’re the one that bought it. I did the same thing for a few years and never bought a plex pass.
