What's the difference between steamOS Holo and the one that's directly from Steam?

[kitnoman]

I have a newbie question. I've seen steamOs Holo and chimera guides. But how different are those from the one that Steam actually provides, steamOS and the actual steamOS for steam deck? Was there any video or guide, where they successfully installed the one that's provided by steam?

Steam's direct download only has drivers for the Steam Deck, while HoloISO has drivers for most non-Nvidia desktops. Getting the SteamOS software running on anything but the Steam Deck would require modifications that would be identical to the modifications for HoloISO, so you might as well just use that. 

 

That other SteamOS you found is SteamOS 2.0, which bares no internal resemblance to the SteamOS on the Steam Deck (SteamOS 3.0). It's a remnant of when Valve tried to make a console (Steam Machines) that was more or less just an ITX gaming PC with nothing proprietary inside like the Steam Deck has. It was a pretty decent distro, but because it was running Debian, it took a while to get updates to things like Wine and Proton, so getting games to run was harder than the much faster moving Arch that SteamOS is now based on.
