Google has published a test release of Chrome OS 101.0.4943.0 (14583.0.0), which offers support for the Steam game delivery service and its gaming applications for Linux and Windows.
Steam is currently in alpha status and is only available on Chromebooks with Intel Iris Xe Graphics GPU, 11th Gen Intel Core i5 or i7 processors and 8GB of RAM, such as Acer Chromebook 514/515, Acer Chromebook Spin 713, ASUS Chromebook Flip CX5/CX9, HP Pro c640 G2 Chromebook and Lenovo 5i-14 Chromebook. When choosing a game, first of all, an attempt is made to launch the Linux build of the game, but if there is no Linux version, you can also install the Windows version, which will run using the Proton layer based on Wine, DXVK and vkd3d.
Games run in a separate virtual machine with a Linux environment. The implementation is based on the "Linux for Chromebooks" (CrosVM) subsystem provided since 2018, which uses the KVM hypervisor. Inside the base virtual machine, separate containers with programs (used by LXC) are launched, which can be installed as normal applications for Chrome OS. Installed Linux apps run similarly to Android apps on Chrome OS, displaying icons in the app drawer. For the functioning of graphical applications, CrosVM provides built-in support for Wayland clients (virtio-wayland) with the execution of the Sommelier composite server on the side of the main host. Both Wayland-based applications and regular X-programs are supported (the XWayland layer is used).
