Acer Predator Triton 500 – RGB Keyboard Flicker Fix (Linux)

Fix on-key RGB Keyboard Flicker on Acer Predator Triton 500 (Linux / Ubuntu 24.04) – A systemd + Python script to stop flickering and initialize RGB lighting via USB HID. Works on boot and resume. Tested on PT515-52.

This script fixes the keyboard flickering issue on the Acer Predator Triton 500 (PT515-52) when running Linux.

The fix sends a custom USB HID command to the RGB keyboard via pyusb and sets it to plain white.

It runs automatically on boot and after waking from suspend.

Supported Keyboards: per-key RGB, not 4-zone

This repo supports full per-key RGB control on Predator laptops with individually addressable keys.
For 4-zone keyboards and Turbo button support, see the wonderfull JafarAkhondali's acer-predator-turbo-and-rgb-keyboard-linux-module.

Background

The RGB keyboard on this laptop uses a per-key RGB which start in a chaotic blinking mode, which makes the laptop almost unsusable with background lighting on. It is also very unprofessional. This script sends a SET_REPORT command to reinitialize a stable static lighting configuration.
