The composite server NIRI 25.08 has been released, featuring the mosaic method (tiling) layouts similar to Gnome broadcasting Paperwm. In NIRI, windows are grouped into a tape that infinitely scrolls on the screen, expanding when a new window is opened without changing the size of previously added windows. The project is based on the Wayland protocol but allows for running X11 applications using the XWALAND DDX server. Written in Rust, the project code is distributed under the GPLV3 license.
Packages for Fedora, nixos, arch linux, and freeBSD are available for installation. NIRI differs from Paperwm by binding windows on each monitor separately, supporting HiDpi, and working on systems with multiple GPUs.
NIRI features an interface for creating and recording screenshots, with the ability to exclude recording of specific windows containing confidential information. Virtual desktops are created dynamically and displayed vertically, while the windows scroll horizontally. Each monitor can have its own set of virtual desktops, with control gestures on the touchpad for switching between desktops and windows.
Configuration in NIRI is done through a file that allows for adjustments in parameters like framework width, indentation, output modes, and window behavior. Changes in the configuration file take effect immediately without the need to restart the composite server.
