An anonymous reader quotes a report from Ars Technica: SteamOS's slow march across the Windows-dominated PC gaming landscape is continuing to creep along. At CES this week, Lenovo announced it will launch a version of last year's high-priced, high-powered Legion Go 2 handheld with Valve's gaming-focused, Linux-based OS pre-installed starting in June. And there are some intriguing signs from Valve that SteamOS could come to non-AMD devices in the not-too-distant future as well. [...] Valve has also been working behind the scenes to expand SteamOS's footprint beyond its own hardware. After rolling out the SteamOS Compatible software label last May, SteamOS version 3.7 offered support for manual installation on AMD-powered handhelds like the ROG Ally and the original Legion Go. Even as SteamOS slowly spreads across the AMD-powered hardware landscape, the OS continues to be limited by a lack of compatibility with the wide world of Arm devices. That could change in the near future, though, as Valve's upcoming Steam Frame VR headset will sport a new version of SteamOS designed specifically for the headset's Arm-based hardware. [...] It's an especially exciting prospect when you consider the wide range of Arm-based Android gaming handhelds that currently exist across the price and performance spectrum. While emulators like Fex can technically let players access Steam games on those kinds of handhelds, official Arm support for SteamOS could lead to a veritable Cambrian explosion of hardware options with native SteamOS support. [...] That's great news for fans of PC-based gaming handhelds, just as the announcement of Valve's Steam Machine will provide a convenient option for SteamOS access on the living room TV. For desktop PC gamers, though, rigs sporting Nvidia GPUs might remain the final frontier for SteamOS in the foreseeable future. "With Nvidia, the integration of open-source drivers is still quite nascent," [Valve's Pierre-Louis Griffais] told Frandroid about a year ago. "There's still a lot of work to be done on that front So it's a bit complicated to say that we're going to release this version when most people wouldn't have a good experience."
