Well today I learned.
I didn’t think “third party” like homebrew would be preferred over ostree-rpm, but makes sense that you shouldn’t change too much from the tested main image.

For anybody else, here’s the exact caveats with rpm-ostree: https://docs.bazzite.gg/Installing_and_Managing_Software/rpm-ostree/#major-caveats-using-rpm-ostree

Personally I mainly used it for fcitx5 language input method some years ago, but I see now that fcitx5 is included in Bazzite, and also that it should work as a flatpak or in distrobox, https://github.com/ublue-os/bazzite/issues/2996

For keyboard, if you’re still having trouble, you can try connecting from the terminal with the command bluetoothctl . Terminal commands often tell you more details than GUIs about why things failed.

Regarding distributions, you are on Bazzite, which is an immutable distribution, meaning the root file system is read-only. That makes it a bit different from “normal” distribution. The upshot is that most things should just work and the system is harder to break. The downside is that you sometimes have to jump through more hoops and do things differently from “normal” distributions when you want to do some deeper level tinkering.

If you search for “How to do X in Bazzite” you might get fewer results because Bazzite is relatively new and niche (though growing quickly).
If you search for “How to do X on Linux” you might find that the steps don’t work because you’re root filesystem is read-only.
So sometimes you need to search for “How to do X on Silverblue” , because Bazzite is (sort of) based on Fedora Silverblue, which is the immutable version of Fedora distribution.

If you want to install some software that you can’t find in the app store (Flathub) or as AppImage, your next step is to look up the command rpm-ostree. It layers new software on top of your read-only root system. Changes from rpm-ostre take effect on the next reboot

The biggest problem with Discord is that its an information black hole. Its not properly searchable and not indexed by search engines.

Discord is fine for casual chat, but horrible when used for forum-type discussions and even worse when used for documentation.

You see the same problems being discussed and solved again and again, but you cant just “link” someone the solution like you could with a forum thread cause its spread out over 3-10 chat messages that are interleaved in-between other topics being discussed in the same room

Anything of long-term value for the project (forum-type discussions, documentation etc) should not recide in Discord
