SteamOS Linux 3.8 released as stable
Points and comments are a snapshot, not live.
SteamOS 3.8 stable release lands with KDE 6.4.3, Wayland, and third-party handheld support.
Valve released SteamOS 3.8.10 for all users, updating the Arch base and adding initial support for upcoming Steam Machine hardware. The release includes KDE Plasma 6.4.3 with Wayland by default in Desktop Mode, support for HDMI VRR, Bluetooth headset mic use, and preliminary hibernation support. The Linux kernel is updated to 6.16. The non-Deck section adds controller and system support for devices including the ASUS ROG Ally series, Legion Go 2, and MSI Claw, and reduces handheld controller input latency from 5-8ms to 100-500us.
What commenters are saying
Commenters are excited about the update, especially the jump to KDE 6.4.3 and Wayland in Desktop Mode. Several warn that SteamOS is not designed as a general-purpose desktop OS, recommending Bazzite or CachyOS instead. A key point is that SteamOS does not support NVIDIA GPUs. Some discuss immutability as a feature, while others ask about using SteamOS without logging into Steam. The thread notes the update ships packages about a year old, but views this as acceptable for a gaming device.
