Help for the setup part..

[akaibukai]

Hi @ldrahnik!

Just noticed that you're also a maintainer/author here :) Thanks!

So I tried to install this in order to the my keyboard keys I have above my numpad. It seems it correctly installed what's necessary when running bash install.sh which I did by selecting the ux582z model..

However, at first it was not working.. Looking at the error messages (python) I was able to get that I needed to add the keys_wmi that was not present by default in the config file... Basically following the Setup part of the readme.. Then, using the commands to discover the keycodes/keys value, I noticed the values in the default ux582z.py were correct for me. So here is the layout.py file I updated:

# /usr/share/asus-wmi-hotkeys-driver/keys_wmi_layouts/layout.py
from libevdev import EV_KEY

KEY_WMI_SCREENPAD = 0x6A  # 106
KEY_WMI_TOUCHPAD = 0x6B  # 107

KEY_WMI_CAMERA = 0x85  # 133
KEY_WMI_MYASUS = 0x86  # 134
KEY_WMI_SWITCHWINDOWS = 0x9C  # 156
KEY_WMI_FAN = 0x9D  # 157

keys_wmi = [
    [ KEY_WMI_SCREENPAD ],
    [ KEY_WMI_SWITCHWINDOWS ],
    [ KEY_WMI_FAN ]
]

I'm only interested with those 3 keys as the others are already working in my case.

But, unfortunately, it was still not working. I tried to debug a little bit (using good old print statements lol).. And when I hit one of these keys it runs down to this part of the asus_wmi-hotkeys.py file (including relevant variables content as comments and skipping unrelevant parts)

# /usr/share/asus-wmi-hotkeys-driver/asus_wmi_hotkeys.py
L142 def handle_events(device, udev):
L143 while True:
L144         # If device (e.g. Asus WMI hotkeys) sends something
L145         for e in device.events():
...
... # e is InputEvent(EV_MSC, MSC_SCAN, 157) for example when pressing KEY_WMI_FAN)
...
L163                 find_custom_key_mapping = list(filter(lambda x: e.value in x or e.code in x or e in x, keys_wmi_layouts.keys_wmi))
# Here find_custom_key_mapping = [157]
...
L277                     try:
L278                         udev.send_events(keys_to_send_press_events)
L279                         udev.send_events(sync_event)
L280                         udev.send_events(keys_to_send_release_events)
L281                         udev.send_events(sync_event)
# with the following values:
# keys_to_send_press_events = []
# sync_event = [InputEvent(EV_SYN, SYN_REPORT, 0)]
# keys_to_send_press_events = []

So it seems that the format of find_custom_key_mapping (one dimension list) is not correct and it's not triggering the for loops we have on the lines 252, 260 and 268:

for ___ in find_custom_key_mapping[0][1:]:

Can you help me figure out what is wrong in here?

Thanks!

Little update.. When I hit a key (e.g. KEY_WMI_FAN), I got in reality a bunch of events at once:

InputEvent(EV_MSC, MSC_SCAN, 157
InputEvent(EV_KEY, KEY_UNKNOWN, 1)
InputEvent(EV_SYN, SYN_REPORT, 0)
InputEvent(EV_KEY, KEY_UNKNOWN, 0)
InputEvent(EV_SYN, SYN_REPORT, 0)

FWIW, when I hit a working key in my case (the keys that are on the Fn row like KEY_WMI_CAMERA) I got the following:

InputEvent(EV_MSC, MSC_SCAN, 133)
InputEvent(EV_KEY, KEY_CAMERA, 1)
InputEvent(EV_SYN, SYN_REPORT, 0)
InputEvent(EV_KEY, KEY_CAMERA, 0)
InputEvent(EV_SYN, SYN_REPORT, 0)

So it seems the KEY_UNKNOWN part is probably the culprit..

Also for completeness here are the other 2 keys that I wanted to get working:

# KEY_WMI_SWITCHWINDOWS
InputEvent(EV_MSC, MSC_SCAN, 156
InputEvent(EV_KEY, KEY_UNKNOWN, 1)
InputEvent(EV_SYN, SYN_REPORT, 0)
InputEvent(EV_KEY, KEY_UNKNOWN, 0)
InputEvent(EV_SYN, SYN_REPORT, 0)

# KEY_WMI_SCREENPAD
InputEvent(EV_MSC, MSC_SCAN, 106
InputEvent(EV_KEY, KEY_UNKNOWN, 1)
InputEvent(EV_SYN, SYN_REPORT, 0)
InputEvent(EV_KEY, KEY_UNKNOWN, 0)
InputEvent(EV_SYN, SYN_REPORT, 0)

@akaibukai Hi again, code below listen for scan codes 106, 156 and 157. The code allows you to send different keys to KEY_UNKNOWN and change value of your fan thermal policy between 0,1,2 changeable for my previous temporary laptop gu603zi via file /sys/devices/platform/asus-nb-wmi/throttle_thermal_policy:

# /usr/share/asus-wmi-hotkeys-driver/keys_wmi_layouts/layout.py

from libevdev import EV_KEY

KEY_WMI_SCREENPAD = 0x6A  # 106
KEY_WMI_SWITCHWINDOWS = 0x9C  # 156
KEY_WMI_FAN = 0x9D  # 157

key_wmi_screenpad = [
    KEY_WMI_SCREENPAD, # we listen for scan code 106
    EV_KEY.KEY_TOUCHPAD_TOGGLE # and in this case will be sent touchpad toggling evdev key instead of unknown one, choose what you want
]

key_wmi_switchwindows = [
    KEY_WMI_SWITCHWINDOWS, # the same as above here, but you can send for example multiple keys together as me <left shift>+<left meta><t>
    EV_KEY.KEY_LEFTSHIFT,
    EV_KEY.KEY_LEFTMETA,
    EV_KEY.KEY_T,
]

KEY_WMI_FAN_THROTTLE_THERNAL_POLICY = '/sys/devices/platform/asus-nb-wmi/throttle_thermal_policy'
KEY_WMI_FAN_THROTTLE_THERNAL_POLICY_VALUES = [
    0,
    1,
    2
]

key_wmi_fan = [
    EV_KEY.KEY_PROG4,
    [
        KEY_WMI_FAN_THROTTLE_THERNAL_POLICY,
        KEY_WMI_FAN_THROTTLE_THERNAL_POLICY_VALUES

    ]
]

keys_wmi = [
    key_wmi_screenpad,
    key_wmi_switchwindows,
    key_wmi_fan
]

What a keys you can use as EV_KEY.xyp you can find here. For fans at first try manually in the terminal whether works echo "0" | sudo tee /sys/devices/platform/asus-nb-wmi/throttle_thermal_policy, echo "1" | sudo tee /sys/devices/platform/asus-nb-wmi/throttle_thermal_policy and echo "2" | sudo tee /sys/devices/platform/asus-nb-wmi/throttle_thermal_policy.
