Linux gaming is in a much better state than it's ever been and that's thanks to Proton but there is a modified version of Proton you've probably heard of and maybe even used called Proton GE and here is Glorious Eggroll the developer of this project, also he is the developer of a distro called Nobara Linux
yeah that’s why I don’t think secure boot or anything related to this will makes its way to nobara, even though it seems like Bazzite have gotten a good system figured out
the LGO PM who dropped by the ChimeraOS discord mentioned that they had talked to valve, and valve had refused working with them because Valve was busy at the time. (in hindsight, it was clearly the Deck OLED that they were busy with)
the PM did say that Valve stated that they would be offering SteamOS for free with a license of some sort, if I'm remembering right.
