[NUC] Programming the Ring LED on NUC6CAY & NUC7ixBN for Linux*
Resolution
Resources to help you program the ring LED when using Linux:
Using WMI to Program the Ring and Button LEDs details two software layers:
- A lower layer, which exposes the LED programming (method) interface in ACPI.
- An upper layer, which exposes the WMI interface for invoking ACPI methods.
While the second (WMI) layer is specific to Windows*, the first layer (ACPI) is OS-independent. There are implementations that support the invocation of ACPI methods in Linux. Here's a place to start: a Linux kernel module that enables calls to ACPI methods through /proc/acpi/call.
The NUC Blog also has information for this: Linux Kernel Driver for NUC LED Control.
