clausmuus:
Eventuell hat sich ja die Ansteuerung der LED geändert. Hier ist die Anleitung zum nuc_led. Teste doch mal, ob Du die auf der Console angesprochen bekommst.

Bei mir funktioniert das neue nuc_led auch nicht, bzw. nuc_led funktioniert jetzt nicht mehr.

Ich lese das in der Anleitung so, dass dieses nuc_led ausschließlich für die NUC8 geeignet ist, wogegen die vorherige Version für die NUC6 und NUC7 bestimmt war:

--- Quote --- Intel NUC8i7HVK LED Control

This is a simple kernel module to control the LEDs on Intel NUC8i7HVK (Hades) kits.

This module is intended as a demonstration/proof-of-concept and may not be maintained further. Perhaps it can act as a jumping off point for a more polished and complete implementation. For testing and basic manipulation of the LEDs, it ought to work fine, but use with caution none the less. This has only been tested on 5.6.x kernels.

This kernel module was initially developed by Miles Peterson (https://github.com/milesp20/intel_nuc_led) for Intel NUC7ixBN and NUC6CAY LED Control, then forked for NIC8ixHVK LED control by Patrick Kullman (https://github.com/nomego/intel_nuc_led).

...jetzt, wo Du das so sagst, würde ich das auch so verstehen... :(

razie:
Was ich grad sehe ... die Syntax für die Ansteuerung der LEDs ist ebenfalls komplett anders.
Es können viel mehr LEDs angesteuert werden...
Vielleicht reagiert die Ring-LED auf eines der Kommandos...

Mal sehen ... vielleicht schaff ich es heute oder morgen mal zu testen, ob man es für den NUC6 doch irgendwie zum laufen bekommt.

@wayne
Hast du da schon was ausprobiert?

Gruß
Ralf
