KLap: Laptop Klipper Optimizer

A lightweight, no-nonsense utility to optimize x86 laptops for Klipper / KlipperScreen duty.

This is part of my Klipper Laptop guide: https://kanrog.com/klipper-laptop-install

Why Klap?

When running Klipper on repurposed "e-waste" hardware, you shouldn't have to fight the OS to keep the printer alive. This script automates the standard tweaks so you can focus on printing, not troubleshooting.

What it does:

• Lid Switch: Disables system suspend when closing the lid, keeping your print running even if the laptop is tucked away.
• NetworkManager: Adjusts polkit authentication to ensure your screen connects without credential prompts.
• KlipperScreen Cursor: Automatically forces the mouse cursor to appear so you can navigate the UI with a trackpad or mouse.

Installation & Usage

1. SSH into your host and run the following commands:

# Download the script
curl -s [https://raw.githubusercontent.com/Kanrog/klap/main/klap.sh](https://raw.githubusercontent.com/Kanrog/klap/main/klap.sh) > klap.sh

# Make it executable
chmod +x klap.sh

# Run with root privileges
sudo ./klap.sh

2. Follow the on-screen prompts and reboot when finished to apply all settings.

Troubleshooting

• "Command not found": Ensure you are in the folder where you downloaded klap.sh and that you used chmod +x.
• Missing Cursor: Ensure your KlipperScreen.conf is located at ~/printer_data/config/KlipperScreen.conf. The script will automatically detect and configure this for you.
