How to install Homebrew package manager on Steam Deck

(See also installing Distroboxm, which is included in SteamOS 3.5 and newer: https://distrobox.it/ )
(See also installing Nix package manager: https://determinate.systems/posts/nix-on-the-steam-deck )

You can install Homebrew (a package manager for macOS and Linux) without disabling the read-only partition with sudo steamos-readonly disable.
The package manager can be used alongside Flatpaks. Some software is only available on Flathub, and some software is only available on Homebrew.

1. Switch to desktop mode (hold power button until a menu appears, then select "Switch to desktop mode")
2. Click the logo at the bottom left, go to System, then go to Konsole

How to record or stream SteamOS 3.X in gamescope (Gaming Mode)

Here is another method that uses Flatpak and obs-vkcapture, which don't meet my personal needs but are very likely to be useful for you. In the comments there there is also an obs-gstreamer method.

Here is another method for recording that has its own GUI for Gaming Mode built with Decky Loader.

Force SteamOS to behave very much like Arch Linux

Key phrase: very much like, not identical. Always treat this as more unstable than Manjaro and only expect support with it in my comments section here.

1. Set a password (if you haven't already) and disable read-only rootfs (yes this means after updating SteamOS [not Steam Client] this will all be deleted and you will have to do all this again if you want

Booting the Steam Deck recovery image

https://help.steampowered.com/en/faqs/view/1B71-EDF2-EB6D-2BB3

SteamOS runs a custom grub to cater it's needs for it's A/B partition design. So far the said custom grub does not boot for me on ovmf/intel uefi (maybe it boots on amd? some said they managed to just rufus the image and boot it)

skip to https://gist.github.com/Kethen/698cfa8cf387e131ebd36fbfbfe9272e#gamescope-and-non-amd-gpu if it just boots for you

Upon closer inspection the official bootloader does load some kind of amd firmware before booting the kernel

"""Flatpak CLI Shortcut Generator

A simple no-argument tool that generates launchers with traditional non-flatpak
command names for your installed Flatpak applications in ~/.local/bin/flatpak.

Does full collision detection and warns you if you forgot to add its output
directory to your PATH. Also overrules the command-line specified in the
``.desktop`` file if the Flatpak maintainer didn't include support for
command-line arguments.
