Arch Linux-based SteamOS 3.7.8 update brings Plasma 6, better battery controls, and Legion Go S support
Valve has officially pushed SteamOS 3.7.8 to the Stable channel, and it’s a hefty one. After months of development in the beta lane, the refreshed version of the Arch-based operating system is finally ready for primetime. This release brings a number of notable enhancements to Steam Deck users and expands support for a growing family of AMD-powered handheld gaming PCs, including Lenovo’s awesome new Legion Go S.
One of the more welcomed changes is the jump to the Linux 6.11 kernel and Mesa graphics stack update, helping to squeeze out more performance and compatibility with newer hardware. But perhaps more impactful for everyday users is the switch to KDE Plasma 6.2.5 in desktop mode, marking a major visual and functional upgrade over the older Plasma 5 environment. This should make the Steam Deck’s desktop experience feel far more modern and snappy.
