Bazzite is an alternative OS to SteamOS for the deck and other handheld PCs. Unfortunately due to a mistake, anyone who installed Bazzite before July 3rd 2024 won’t get automatic updates.
If this affects you, I’d suggest checking out the article to get instructions on fixing it.
It has all the advantages of steamOS, can boot straight into game mode, supports Decky plugins, etc.
However it also supports installing traditional Linux programs permanently (which steam OS generally won’t let you do), and has other benefits too.
