# Orion Unchained: reconstructing Acer Predator Orion lighting control

> Orion Unchained reconstructs Acer Predator Orion desktop lighting control for Linux through a kernel driver, command-line client and desktop app. Its investigation documents PredatorSense lighting payloads, the firmware's AcerGamingFunction WMI methods and the SMBus controller path; the driver uses those findings to set and read lighting effects on the tested PO7-660.
