Ubuntu has launched public testing for a Snap package of Steam on ARM64 systems, using FEX emulation to bridge the gap from x86 support. This move aims to bring Valve's gaming platform to ARM-based Linux devices like laptops and single-board computers. The initiative marks a significant step toward broader compatibility, though it remains experimental.
Steam, Valve's popular gaming platform, has long been limited to x86_64 architecture on Linux, forcing ARM64 users to rely on unofficial workarounds. On January 9, 2026, Ubuntu announced public testing of a new Snap-packaged version tailored for ARM64 devices, including modern laptops, single-board computers (SBCs), and servers repurposed as desktops.
The Snap leverages FEX, a user-space emulation layer that dynamically translates x86 and x86-64 instructions to run on ARM64 CPUs. This method forwards graphics and system calls to the host system, bypassing the immediate need for recompiling Steam or games for native ARM support. Testing focuses on key areas: installation reliability, startup behavior, game compatibility, controller support, and overall system integration.
Ubuntu emphasizes that this phase is experimental and not suitable for production use. Feedback from testers will help resolve issues before wider distribution. If successful, this could provide the first officially supported method to run Steam on ARM64 Linux, with native versions remaining a longer-term goal.
Users with ARM64 devices can participate by installing the Snap, as detailed in Ubuntu's Discourse announcement. Early reports highlight improved performance on Linux ARM systems compared to previous emulation attempts.
