screensaver

A simple Linux screensaver framework

Prerequisites

• A X11 based Linux distribution to run the launcher.
  • The launcher does not support Wayland yet.
• A working Go and C compiler and installed Raylib dependencies.
  • https://go.dev
  • https://github.com/gen2brain/raylib-go#requirements

How it works

This framework is composed of multiple parts, a launcher, multiple savers and a command tool to send commands to the launcher. The launcher is responsible for the launching of the savers, while the savers themselves just draw something nice on-screen and exit when input is detected.

The launcher uses a timer, that when expired, will launch the defined executable. Any input will reset the timer and delay the launch.

Install

Just run the install.sh script. This will compile and install the various binaries.

Add to startup

It differs between different Linux distributions but just add the launcher to startup with the necessary options.

Example

screensaver-launcher -timer 15m -saver screensaver-game-of-life > /dev/null 2>&1

In this example you can see the screensaver-game-of-life saver is being executed after the timer expires but any executable can be launched.

Commands

You can use the command tool to send commands to the launcher to control its behaviour.

Command	Description
screensaver-command -reset	Reset the launcher timer.
screensaver-command -activate	Expires the timer and activate the specified saver.
