I am running Faustus and Aurora to control keyboard backlight which worked perfectly, until setting secureboot for a couple of games on Windows (dual boot, separate physical drives) I had to create a MOK for Faustus so it wou= ld load correctly. Let me know if I can be of more help. ------------ Chatty G output: On ASUS TUF Gaming A16 (board FA608UM), the kernel module mfd_aaeon binds e= arly and prevents asus_nb_wmi from loading. This causes asusd to fail with "MissingFunction('asus-nb-wmi not found')" and breaks keyboard backlight control and other ASUS WMI features. Symptoms: - asus_nb_wmi fails with "No such device" - asusd fails to start This occurs regardless of Secure Boot state. Blacklisting mfd_aaeon restores correct behavior. Expected behavior: asus_nb_wmi should bind to the device on this system, or mfd_aaeon should n= ot bind on this DMI match. Workaround: blacklist mfd_aaeon ------- Hardware: System manufacturer: ASUS Product name: TUF Gaming A16 Board name: FA608UM ------- $ dmesg | grep -E "aaeon|asus_nb_wmi|asus_wmi" [ 3.733678] asus_wmi: ASUS WMI generic driver loaded [ 3.738550] asus_wmi: Initialization: 0x1 [ 3.738692] asus_wmi: SFUN value: 0x21 [ 3.767492] asus_wmi: fan_curve_get_factory_default (0x00110032) failed:= -19 [ 13.315905] asus_wmi: Unknown key code 0x4f -------- $ sudo dmidecode -s system-manufacturer sudo dmidecode -s system-product-name sudo dmidecode -s baseboard-product-name [sudo] password for preen:=20=20=20=20=20 ASUSTeK COMPUTER INC.
