This behavior was first observed on a Tuxedo notebook and was belived to be a hardware quirk. However, it seems that i simply misunderstood the manual of the OEM software for Intel NUC devices. The correct behavior is: - fn_lock_toggle_enable enables/disables FN lock mode - super_key_toggle_enable enables/disables the super key Rename both sysfs attributes to avoid confusing users.

The driver uses a ACPI interface to talk with the embedded controller, but relies on a ACPI WMI interface for receiving event notifications. The driver is reverse-engineered based on the following information: - OEM software from intel - https://github.com/pobrn/qc71_laptop - https://gitlab.com/tuxedocomputers/development/packages/tuxedo-drivers - https://github.com/tuxedocomputers/tuxedo-control-center The underlying EC supports various features, including hwmon sensors, battery charge limiting, a RGB lightbar and keyboard-related controls.
