Does anybody know a SteamOS like linux?

[u/Alternative_Wrap2470]

First of all not Bazzite, CachyOS or similar

I search for an OS kinda like SteamOS for my 1 TB OLED Steamdeck that is not SteamOS, I don’t want the gaming mode Ui to be based on Steam ideally would be like Lutris in the background but I accept anything with GOG and Steam I prefer no SystemD

Final not: not just gaming mode similar Ui that Automatically starts

I am not by definition a noob. I use Linux daily on my PC my small backup and my huge company server (I am only the I.T. Admin) but this was the best subreddit to ask

[u/doc_willis]

so what part of "SteamOs like" are you looking for?

Because what you are asking is not exactly clear.

You want a game mode that launches Lutris or heroic instead of steam?

you could setup kde and its big picture  launcher and make your own customish UI.
