Jay is a Wayland compositor.
This is free and open source software.
Features include:
- Configurable by a declarative TOML file or a shared library that gets injected into the compositor.
- i3 look and feel. Colors, sizes, and fonts can be customized.
- Stable. Jay also aims to be forward and backward compatible for existing setups, allowing you to upgrade or downgrade the compositor without having to adjust your configuration.
- CLI – can be used to configure the compositor at runtime.
- Multi-monitor support – can be used with multiple monitors with hot-plug and hot-unplug support. When a monitor is unplugged, all workspaces are automatically moved one of the remaining monitors. When the monitor is plugged in again, these workspaces are restored.
- Multi-GPU support – can be used with multiple GPUs and monitors connected to different GPUs. One GPU is always used for rendering the desktop. You can change this GPU at runtime.
- Supports screen sharing via xdg-desktop-portal. There are three supported modes:
- Window capture.
- Output capture.
- Workspace capture which is like output capture except that only one workspace will be shown.
- Screen locking.
- Supports the zwlr_layer_shell_v1 protocol used by notification daemons.
- Per-monitor fractional scaling support.
- Can use either OpenGL or Vulkan for rendering. Vulkan offers better performance and memory usage but OpenGL is still provided for older hardware.
- Supports explicit sync for compatibility with NVIDIA hardware.
- Supports clipboard managers via zwlr_data_control_manager_v1.
- Splits protocols into unprivileged and privileged protocols. By default, applications only have access to unprivileged protocols. You can explicitly opt into giving applications access to privileged protocols via the Jay CLI or shortcuts.
- Supports leasing VR headsets to applications.
- Supports adaptive sync with configurable cursor refresh rates.
- Supports tearing presentation for games.
- Uses frame scheduling to achieve input latency as low as 1.5 ms.
