SteamOS beta update adds controller support and fixes for Steam Deck and Steam Machine

The latest SteamOS beta introduces significant improvements for the Steam Deck and Steam Machine, including enhanced controller support and critical system fixes. A key update enables the original 2015 Steam Controller to wake the Steam Machine from sleep, alongside a new driver feature that allows the controller to function as a mouse and keyboard replacement even when Steam is not actively running. The update also addresses several hardware-related issues, such as resolving lockups caused by hot-plugging HDMI displays in desktop mode and fixing a bug where TVs with HDMI "Game Mode" caused boot delays. Additionally, the update includes a firmware patch for the Steam Machine to prevent CPU performance degradation after sleep and fixes for Wi-Fi connectivity issues. Beyond Valve’s own hardware, the update expands support for third-party handhelds, including the MSI Claw and OneXPlayer, while resolving input registration bugs. The Linux kernel has also been updated to version 6.18.42, and users are advised that some devices may experience performance regressions while using this beta version.
