Saying RAM can help because you can reencode the video to h.264 or h.265 to make use of hardware decoding is more than a bit of a stretch. You can just reencode it to the normal disk instead. Unless it’s the speed of the local block device that’s the bottleneck here (and there’s no indication that it is, and it would be extremely unlikely), using a ramdisk/tmpfs for any part of that is just pointless.

Modern CPUs (from like the last 20 years) will throttle down a lot before they actually shut down. Unless your cooling is completely inadequate or somehow broken, shutdowns because of high load just dont happen. I suspect there is something fundamentally wrong with your hardware.

A problem with cooling could also go some way to explaining your performance problems – but it could also just be that your system just doesn’t have the computing power to do what you want it to. The computing demands from video decoding go up dramatically when you go beyond 1080p. If I recall correctly, the Intel Core CPUs with the “U” at the end were the low-energy models (for longer battery life); of course that comes with compromises on the performance side.

The CPU model suggests that this is a laptop, and a fairly old one at that. I would look for things like blocked air ducts or broken fans if I were you. It’s also possible that the thermal compound between your CPU and the CPU cooler has dried out and needs replacing (although laptops of that power class should be using thermal contact solutions that do not dry out), or that contact has lessened for other reasons. Again, if your computer seriously powers down because of load, it’s borderline broken and in need of maintenance.

As for your other question, no RAM cannot help with that. It can hurt if you have too little of it, but once you have enough, the best it can do is not be a bottleneck.

* Edit: Also, make sure you are not setting down the laptop on anything soft, like a blanket, when using it. It will sink in and have its air intakes blocked if you do that.

Rimworld for me.

(I have never tried Dwarf Fortress.)

Honorable mention goes to War Thunder, while it isn’t on of my favorites, I was still a bit blown away to find out it runs natively on Linux.

The KDE team has already determined that this is not a bug and that both you and me must just be imagining it:

Smartctl works on nvme drives. Use it.

btop for bling

htop for practical utility

top for minimalism, availability, reliability

groundzero

Several years ago now. On at least two of those tries, after maybe a month or some of daily driving, suddenly the fs goes totally unresponsive and because it’s the entire system, could only reboot. FS is corrupted and won’t recover. There is no fsck. There is no recovery. Total data loss.

Could you narrow it down to just how long ago? BTRFS took a very long time to stabilise, so that could possibly make a difference here. Also, do you remember if you were using any special features, especially RAID, and if RAID, which level?

Out of interest, since I’ve not used the “recommended partion setup” for any install for a while now, is ext4 still the default on most distros?

I recently installed Nobara Linux on an additional drive, because after 20 years, I wanted to give Linux gaming another shot (works a lot better than I had hopes for, btw), and it defaulted to btrfs. I’ll assume so does Fedora, because I cannot imagine Nobara changed that part over the Fedora base for gaming purposes.

Well passwordless.

Same thing in this context. But sure, an encrypted partition would work.

Dunno about ideal, but it should work.

It does have quite a bit of overhead, meaning it’s not the fastest out there, but as long as it’s fast enough to serve the media you need, that shouldn’t matter.

Also, you need to either mount it manually on the command line whenever you need it or be comfortable with leaving your SSH private key in your media server unencrypted. Since you are already concerned with needing to encrypt file share access even in the local network, the latter might not be a good option to you.

The good part about it is, as long as you can ssh from your media server to your NAS, this should just work with no additional setup needed.

Interesting. Though it does seem to to require your private key to be unencrypted…

Is sshfs an option? Unfortunately, I don’t think you can put that into /etc/fstab, though…

This is on Ubuntu 22.04.3 LTS, so well within the 5 year window. I’m complaining because I kept getting frantic calls from people using that who didn’t know what was going on.

That would be all absolutely fine and dandy if I could easily just opt out in a way that makes the system stop bothering me about it. But I can’t.

Pro tier is for Enterprise customers who need extra-long term support and are willing to pay for it. Canonical is meeting a market demand so they can remain competitive for use in those environments, which is good for everyone. It’s benign

Then please show me the button (and I mean button, not command-line exclusive settings or config file entries in /etc, and certainly not unofficial trickery like third party repositories that replace Ubuntu advantage packages with an empty decoy) that says “Thank you, I don’t need Ubuntu Pro, please stop nagging me about it”.

Depends a lot on what kind of user. I specified “non-technical” with a reason. I have, in the past, recommended Ubuntu to a small number of friends and family members. These are people who aren’t particularly comfortable using computers in the best of times. They very much don’t need the newest, best and most shiny versions of everything. They need to do billing, taxes, correspondance, email and various other tasks related to their small business, they need that to work reliably, and if at all possible, to work exactly the same way as it did the last five years. And if there is any pop-up they don’t immediately understand (for example because it’s in English instead of their native language, yes that still happens in Ubuntu quite a bit), they will call me on the phone.

I don’t know if you’ve ever had to support non-technical end-users, but for some of them, even something as seemingly trivial as a menubar that has moved from the top to the side can be issue that needs explaining and training. For that kind of user, I really do want to postpone all updates beyond pure bug and security fixes for as long as reasonably possible. Five years sounds reasonable. Six months does not.

And constant non-optional pop-ups nagging you to upgrade to Ubuntu Pro during those five years. I’d actually be kinda okay with it if it were only after, an if just as a reminder that, hey, the LTS period is over, you need to switch to the next LTS release now.

With the LTS versions being the best and obvious choice for your average non-technical user who just wants to get some work done…

They do, including those that are in Debian, but they also have an additional source of faster security updates developed in house, which they hold back from the free path in favor of the pro package.

Personally, I feel a bit torn about this. On the one hand, this should be, officially at least, purely an additional service on top of what’s available in the baseline distro, and isn’t taking anything away from that.

On the other hand, I strongly disagree with holding back security fixes from anyone, ever, for any reason. Also, the claim that it will never take away anything from the free base distro is at least a little bit suspect. I would not be surprised if the existence of the pro path were to gradually erode the quality and timelyness of the base security upgrade path over time. Also, Ubuntu is now very annoying about nagging you to upgrade to pro, and the way to disable that is fairly involved and very much non-official. The whole thing goes against what I expect from a F/OSS operating system. I don’t quite understand why this topic hasn’t been a much bigger issue in Linux circles yet. It certainly doesn’t sit right with me…
