Introducing Stasis: A Modern Solution for Idle Management on Wayland
The transition to Wayland has brought significant security and performance improvements to the Linux desktop. However, this modern display server protocol handles certain tasks differently than its predecessor, X11. One of the most critical functions affected is idle management—detecting when a user is inactive to trigger actions like screen locking or changing a status to “away.”
A new tool, Stasis, has emerged as a clean, modern, and efficient solution to this challenge. It acts as a dedicated idle manager for Wayland, providing a crucial piece of infrastructure for a secure and functional desktop experience.
The Core Problem: Idle Detection in a Secure Environment
Under the old X11 system, applications could easily monitor system-wide input events to determine if a user was active. While functional, this approach posed a significant security risk, as any application could potentially act as a keylogger.
Wayland, by design, isolates applications from one another to prevent such vulnerabilities. This means a random application can’t simply spy on your keyboard or mouse to see if you’re there. While this is a massive win for security, it creates a new problem: how do applications legitimately know when to perform idle-based actions? The answer lies in using a standardized protocol, and that’s precisely where Stasis comes in.
What is Stasis and How Does It Work?
Stasis is a lightweight daemon that correctly implements the ext-idle-notify Wayland protocol. This protocol is the modern, officially sanctioned method for securely handling idle state notifications.
In simple terms, Stasis runs quietly in the background, monitoring for user activity. Other applications can then ask Stasis two simple questions:
- Is the user currently idle?
- Please notify me after the user has been idle for a specific amount of time.
This approach provides a centralized and secure service that any application can use without compromising the core security principles of Wayland. It is desktop-environment agnostic, meaning it can be used on any Wayland compositor that supports the necessary protocol, from Sway and Hyprland to GNOME and KDE.
Key Benefits of a Dedicated Idle Manager
Implementing a proper idle manager like Stasis provides several tangible benefits for security, usability, and system efficiency.
- Enhanced Security: This is the most critical advantage. By reliably detecting user inactivity, you can trigger your screen locker to engage automatically after a set period. Properly configured idle-locking is a foundational security practice, preventing unauthorized access to your machine when you step away. Stasis ensures this process is dependable on Wayland.
- Improved User Experience: Many applications can benefit from knowing the user’s idle state. For example, a chat client can automatically set your status to “Away,” or a video player can prevent the screen from sleeping during playback.
- Greater System Efficiency: Stasis can be used to trigger power-saving features like turning off displays after a prolonged idle period. Advanced users can even script it to run resource-heavy background tasks, such as system backups or data processing, only when the computer is not in use.
Actionable Security Tip: Integrating Stasis with a Screen Locker
To get started, you’ll typically install Stasis through your distribution’s package manager or by building it from the source. Once installed, integrating it is straightforward.
For example, to lock your screen with swaylock after 5 minutes (300 seconds) of inactivity, you could use a simple command in your startup configuration:
stasis-client -t 300 'swaylock -f'
You can also configure a second timeout to turn off your displays for power saving:
stasis-client -t 600 'swaymsg "output * dpms off"'
This simple but powerful integration ensures your system is both secure and energy-efficient, leveraging the modern architecture of Wayland without compromising its security.
As the Linux community continues to embrace Wayland, tools like Stasis are essential for bridging the functionality gap left by older X11 utilities. It provides a robust, secure, and standardized solution to a fundamental desktop requirement, making it a must-have for any security-conscious Wayland user.
