pranklock

Based on the original work of @Adimote in this version.

Locks the screen with a screenshot of the desktop. If any key is pressed, or the mouse moves, capture an image with the webcam, and lock the screen again using that.

Dependencies

• i3lock
• ffmpeg
• xdotool

Usage

1. Install the above dependencies
2. Run the pranklock script to lock your screen

By default, the first webcam (/dev/video0) is used. To change this, pass the video device as an argument (eg pranklock /dev/video1)

3. To safely unlock without showing the webcam image, press the Escape key. You can then unlock as normal.
