The Steam Deck game console runs on SteamOS, a variant of Arch Linux. While you typically use the Steam Deck like any other dedicated game machine, you can freely drop into a Linux Desktop mode of surprising and powerful potential.
The Steam Deck, the versatile game console that Valve began selling in 2022, is hardly the first consumer-oriented technology that runs Linux under the hood. Readers of this magazine might have fond memories of the original TiVo boxes, for example, or have noticed a full copy of the GPL lurking in the deepest recesses of their cars' dashboard UI.
