I don’t know if it even works, but have you considered relying on their Stealth protocol? While its absence on Linux _{(and Windows)} means that you might not even be able to make use of it in the first place, I’m still interested to know if it makes any difference.

Thank you for reporting back! Much appreciated!

So it turns out, I cannot use my NVIDIA card using distrobox. I guess it only works with AMD?

Interesting. Unfortunately, I don’t own an Nvidia device. Therefore, I can’t tackle it myself. Distrobox should allow the use of Nvidia, but I’m unaware if this applies to the bazzite-arch container as well. The picture you shared and the link to its FAQ-page (found below) do suggest otherwise, unfortunately…

I was wondering if distrobox would somehow allow better performance

FWIW, I’ve always experienced better performance inside the bazzite-arch distrobox container, at least compared to Flatpak*.

I see that this image is used a lot on Steam Deck, which I also don’t understand why (as opposed to having everything native).

Because the distro image it’s used in conjunction with, Bazzite, is Fedora-based, while Steam OS is based on Arch. Bazzite is Fedora-based in the first place, because Arch doesn’t officially have any plans for ‘immutable’ distros yet. As for the remaining distros, only Fedora and NixOS (see Jovian-NixOS) have a sufficiently mature and suitable platform at this point in time.

maybe I am missing some graphical dependencies

This happens way more often than you might expect. Even the so-called ‘toolbox’ containers from Distrobox miss a lot of packages required to support software graphically. Consider running it inside a terminal and pay attention to error codes etc; those might/should help you resolve the issue. Sometimes it helps to explicitly use the -v or --verbose option to ensure that the program actually communicates what’s happening.

Am I wrong to assume that this doesn’t add anything beyond what uBlock on medium mode does already? Except (perhaps) ease-of-use and the blocking of first-party trackers; if those even exist*.

Don’t get me wrong; I love EFF’s work and their commitment to digital privacy. I just want to understand if I, personally, would need it.

I cannot wait to get home and try it out!

Please consider reporting back after you’ve tried it; I’d love to read your experiences.

Wouldn’t it be fun to have “a ready-to-game Arch Linux based OCI designed for use exclusively in distrobox”?

Besides the already mentioned Star Labs and System76, there’s also Insurgo, Nitropad and NovaCustom.

As for an exhaustive list on the matter, unfortunately, I don’t think something like that is out there. Though both Canoeboot (formerly known as Libreboot) and Dasharo do have their own respective lists.

The simple virtue of being able to genuinely express these words; “I don’t know”, “Sorry” and “Thank you” (or any derivative of these*).
