Rickroll from seemingly unlocked laptop

At work we have a tendency of sending highly inappropriate content from other colleagues laptops, if they forget to lock them

If you have similar, neat working environment – and want to have fun with the lurkers that await for a unprotected computer – fetch never-gonna script and start it before leaving your machine

Python code with bindings to Tk GUI simply shows an image of your like, one that resembles unlocked desktop (i.e. IDE with opened project or some emails) and actually locks screen with xflock4 on any keyboard or mouse event, showing our dear Astley in a genuine rick-rolling fashion

Proper Rickrolling

Correct image is important, so here is how to get the most prominent Astley representation – retrieve the signature song in best video quality and extract a recognizable photo for the lock screen

Dev setup involved XFCE, Mint and light-locker, but the code can be used in any DE / screensaver combination

Fetch py code, install tkinter (e.g., sudo apt-get install python3-tk) and Pillow (pip install -r requirements.txt) and ensure lightdm-gtk packages are in place


Fire up lightdm-settings, choose Mr Rick for the background, toggle Draw user backgrounds, update HONEYPOT and XFLOCK in astley.py and enjoy subtle jesting
