Well it’s hard to find it since github removed it for naming issue but it’s on an alternative git repository hoster.

Has an issue with the speaker and not updated for a while but probably work otherwise if upgraded to testing/sid …

A bit sad how Valve made a mess with Steam OS since it moved to Arch, they could had baked drivers/firmwares/feature into the Linux kernel, they made a Frakenstein Arch build mostly using flatpaks and an immutable partition locking up the device a stupid way …

So SteamOS console mode is polished but the desktop experience quickly fail to deliver …

Valve stayed true to their promise, no major upgrade but it also mean that oled versions are mostly worthless unless you need an upgraded feature, the aim is to keep all the steam decks relevant for a long time as games consoles of Microsoft, Nintendo and Sony, otherwise a major upgrade would have killed all their efforts, so expect minor upgrades when new standards start or when hardware cost goes lower.

A Debian testing (unstable/sid otherwise until hardware work on testing) setup with libregaming github tools, game streaming tools/services like on boilingsteam website and a vfio setup check reddit) should do. [most games should work that way apart really few fps games]

You could use a time machine like backup tool or btrfs snapshots.

DAW will be best with a low latency kernel, pulseaudio, Pipewire and jack, check Bitwig, Ardour and Reaper. [still complex on Linux]
