Roguauto (ログアウト)

Roguauto is a lightweight and configurable power-menu daemon for Wayland, written in Rust.

The application runs as a persistent per-user daemon and displays a native wlr-layer-shell overlay when requested through its local ipc interface.

App features

• Lock, suspend, hibernate, reboot, shut down, and log out.
• Native Wayland rendering without GTK or inheritance from the system theme.
• A fully application-controlled visual style.
• TOML configuration with filesystem-based hot reloading.
• Keyboard and pointer navigation.
• A persistent system D-Bus connection to systemd-logind.
• A simple Unix-domain-socket daemon interface.

Compatibility

The compositor must support the wlr-layer-shell protocol.

The application was developed and tested primarily on Niri. Other compositors implementing wlr-layer-shell, including Hyprland, Sway, Labwc, KWin, etc, are expected to work.

GNOME Shell does not currently expose wlr-layer-shell, so it's not supported.

Power operations additionally require Linux, a working system D-Bus, and systemd-logind. Some actions may require authorization through PolicyKit.

Usage

The daemon is started with:

# A path to a config file can be optionally given.
rogu daemon [-c <file> | --config <file>]

In a second terminal window while the daemon is still running:

rogu show
rogu hide
rogu toggle
rogu quit

However, normally, you would want to start the daemon as part of your compositor's startup or autostart processes. And then, bind a keyboard shortcut to rogu toggle and/or the remaining commands.

Architecture

The main thread runs a Calloop event loop responsible for:

• Wayland and Smithay Client Toolkit events,
• keyboard and pointer input,
• shared-memory buffer management,
• rendering,
• configuration reload notifications.

A Tokio runtime handles asynchronous work such as:

• systemd-logind calls through zbus,
• daemon IPC,
• other background I/O.

Results from asynchronous tasks are returned to the main thread through a Calloop channel. Wayland objects remain confined to the Calloop thread.

Rendering

The menu is rendered using shared-memory buffers with Tiny Skia. Cosmic Text performs text shaping and glyph rasterization, while embedded SVG assets provide scalable action icons.

The renderer does not use GTK and therefore does not inherit the user's GTK theme. Colors, dimensions, typography, spacing, and corner radii are controlled by the application's configuration.
