I switched over to pipewire for my audio nearly 2 years a go and had 0 problems migrating from pluse to pipewire in Arch btw. You’ll be running an even newer version so it will be just be a drop in replacement and the worst you’ll have to do is restart the pipewire service when you install it or just reboot.
What I cannot recommend is the Xbox One S controller because the bluetooth latency is absolutely terrible for anything that isn’t turn-based combat and even then navigating menus is still sluggish unless you are using the official MS wireless adapter. That requires a separate kernel module which you have to re-install every time there’s a SteamOS version update.
Flatpak probably has it’s specific uses like trying to use one piece of proprietary software that you don’t trust and don’t want to give it too much access to your system, or most GUI software clients having an easy way to install Discord on your Steam Deck (no terminal usage, Linux is easy yay), but native packages 99% of the time work better.
In terms of plug and play, using KDE Plasma, trying to mount USB NTFS drives with Dolphin fails because udisks2 needs a new release with an NTFS patch so you’ll need to mount those using the terminal (and possibly a umask argument that I can’t remember off the top of my head if you want r/w access instead of read-only). Internal drives that are NTFS worked by clicking on them with no extra steps required surprisingly. This was with a newer kernel that has the ntfs3 driver and not using ntfs-3g fuse driver which also ‘just works’ but is slower.
i do not see the hype for immutable distros, they seem to be for an incredibly niche sub-section of the linux desktop which is already incredibly niche (i’ll probably be answering my own question). good for the devs for trying new things i guess but these seem like hell to use if you are a tinkerer, gnome is whack and won’t convince any new users to use linux. it seems like an operating system i’d install for my tech illiterate parents so i won’t have to troubleshoot anything if it had a desktop like cinnamon or kde because they would have some familliarity with a windows like ui.
“no.”
