Locker Screensaver

This Python program creates a screensaver that locks the screen and prevents the system from going to sleep. It also moves the cursor to random positions on the screen at regular intervals.

Features

  • Saves display resources and elecctricity by turning off the backlight and screen
  • Fullscreen mode with hidden cursor
  • Customizable text display
  • Cursor movement to random positions at regular intervals
  • Prevents system from sleeping
  • Handles Ctrl+H to exit the application
  • Ignores Home button press

Requirements

  • Python 3.x
  • tkinter module
  • xdotool utility
  • xset utility

Installation

  1. Install Python 3.x if not already installed.
  2. Ensure tkinter, xdotool, and xset are installed on your system.

Usage

  1. Clone the repository: 
    git clone https://github.com/aronbergman/screensaver_linux.git
cd screensaver_linux
  2. Run the program: 
    python locker.py
    If screen dimensions are not provided, the program will detect them automatically.

How It Works

  • The program creates a fullscreen Tkinter window with a hidden cursor.
  • A label with custom text (currently empty) is displayed.
  • The cursor is moved to random positions on the screen every 55 seconds.
  • The system is prevented from sleeping by calling xset regularly.
  • The program handles Ctrl+H to exit and ignores Home button presses.

Customization

  • To customize the displayed text, modify the text variable in the locker.py file.
  • Adjust the cursor movement interval by changing the time.sleep(55) value in the move_cursor function.
