I saw another post here, that it is working on the same model. But it is not working at all here (Manjaro). The Neo 16 has these randomly blinking keys at startup and these remain blinking. But I have the same model

sudo dmidecode -s system-product-name
Predator PH16-71

and I have checked, that the directory exist

file /sys/bus/wmi/devices/7A4DDFE7-5B5D-40B4-8595-4408E0CC7F56/
/sys/bus/wmi/devices/7A4DDFE7-5B5D-40B4-8595-4408E0CC7F56/: directory

The acer_wmi module is unloaded and I have the facer module loaded:

facer                  53248  0
platform_profile       12288  1 facer
i8042                  57344  1 facer
sparse_keymap          12288  1 facer
rfkill                 40960  10 iwlmvm,bluetooth,facer,cfg80211
video                  81920  5 nvidia_wmi_ec_backlight,facer,xe,i915,nvidia_modeset
wmi                    32768  4 video,nvidia_wmi_ec_backlight,wmi_bmof,facer

The character device is there:

ls /dev/acer*
/dev/acer-gkbbl-0  /dev/acer-gkbbl-static-0

But no matter, what I configure with keyboard.py or facer_rgb.py, I only have the randomly blinking keys.
