Not Working with Kernel 5.13 (Ubuntu 21.10) #33

Closed macbrownzie closed 2 years ago

Good Evening,

I updated my ZenBook to Ubuntu 21.10 (Kernel 5.13) today and tried the remove and reinstall. Like 5.11 the keyboard special keys seem to work okay, but the /sys/class/leds/asus::screenpad folder is NOT being created so the brightness file isn't accessible.

Any assistance would be greatly appreciated.

Thanks in advance

Thanks SO much to Dave Jensen (jibsaramnim)!!

With his help I was able to determine that the issue with loading this on Ubuntu 21.10 (Kernel 5.13) was some kind of loadable module order or priority error. When the mfd_aaeon kernel module is loaded BEFORE the asus_wmi and asus_nb_wmi, the /sys/class/leds/asus::screenpad folder is not created properly.

If the mfd_aaeon, asus_nb_wmi and asus_wmi are rmmod(ed) and modprobed after boot-up the necessary files are created and the screenpad functions as expected.

Another solution is to simply blacklist the mfd_aaeon module and then the asus_wmi and asus_nb_wmi work as expected.

If anyone has any information on what the mfd_aaeon module is, please post it here.

Thanks, _Macbrownzie
