Karabiner-elements: 0.90.84 breaks Fn keys on external bluetooth keyboard

[hostmaster]

I've got Kinessis Freestyler2 Blue keyboard after upgrade to 0.90.70 all hot keys are broken. for example f4 performs volume up. If karabiner is quited everything works as expected.
My config is simple

{
    "profiles": [
        {
             "name": "Default profile",
            "selected": true,
            "simple_modifications": {
                "caps_lock": "f19"
            }
        }
    ]
}

Same here -- brightness up/down does not work anymore on my apple bluetooth keyboard. The capslock key LED is permanently lit up. I'm using the standard config that maps caps lock to escape.

@hostmaster I guess your keyboard is not sending properly function key events in order to simulate macOS function keys. (eg. your physical f4 key sends f12 key events)
Please modify the function key mapping in Function Keys tab in Karabiner-Element Preferences.

[tekezo]

The brightness up/down highly depends on the display hardware.
Please upgrade to v0.90.72 and try the apple_display_brightness_decrement and apple_display_brightness_increment in Function Keys tab.

About the caps lock LED, if the caps lock LED is lit up before Karabiner-Elements start, Karabiner-Elements keep the state.

[hostmaster]

@tekezo it is not the case, all keys are working properly if karabiner-elements is not running.

after upgrade to 0.90.72 Fn keys are functional again but mapping cap lock -> f19 does not work now.

I followed the article CapsLock input source switching in Mac OS X but seems like now cap lock does not generate events at least EventViewer shows nothing.

and the same thing has happened for internal keyboard as well

[tekezo]

@hostmaster Due to the macOS limitation, Karabiner-Elements have to change f1-f12 keys to media control by itself. So, Karabiner-Elements changes f12 key event to volume up.
Some Mac Model keyboards sends improper key event for physical f3 and f4 keys because macOS has interpreted f10-f12 key events to mission control, dashboard.
These combination causes your issue.

About caps lock key, there are any error message in Log tab of Karabiner-Element Preferences?

[hostmaster]

@tekezo volume up/down, dashboard and mission control work as expected with 0.90.72

there are warnings in Log tab

@hostmaster Thank you for information!

There is an issue that Karabiner-Elements requires to reboot after install (eg #527 )
But I have not succeed to reproduce the issue yet.

I would like to know the result of this command in Terminal.

sudo kextload /Library/Extensions/org.pqrs.driver.Karabiner.VirtualHIDDevice.kext

[hostmaster]

@tekezo thank you the output is below

sudo kextload /Library/Extensions/org.pqrs.driver.Karabiner.VirtualHIDDevice.kext

I'm not rebooting the system in case you need more details.

[tekezo]

@hostmaster Thank you for information.
It's very strange, the installation post process seems to be not executed for some reason...
Could you install Karabiner-Elements again?

[hostmaster]

@tekezo after some re-tries and system reboot the module is loaded finally. However it breaks hotkeys (Fn) keys again. Some Fn keys has no effect now (Dock, Volume)

From the EventViewer. Karabiner is running. I pressed MissionControl key (F3)

From the EventViewer. Karabiner is running. I pressed Dashboard key (F4)

From the EventViewer. Karabiner is not running. I pressed MissionControl key (F3)

From the EventViewer. Karabiner is not running. I pressed Dashboard key (F4)
There are no events at all.

[tekezo]

@hostmaster Thank you for feedback.

About f3 key

I'm confirmed that the key order is swapped with the hardware macro keys.
(eg. your f3 key which sends control+up)

I've fixed this issue at v0.90.73.

About f4 key

I guess your f4 key sends f12 key event.
Please try this configuration.

[hostmaster]

@tekezo 0.90.73 MissionControl key (F3) works now.

I made the change you have sugested. Dock key (f12) shows dock key still. f4 shows launchpad with dashboard and with launchpad

F12

[tekezo]

The f12 key seems sending some key combination like f3 key.
Can you bind the key combination to your desired function in System Preferences > Keyboard > Shortcuts?

[hostmaster]

yes it is. you are right. however there are some issues still.

Power button does not work on external keyboard.

I recorded all these events when karabiner did not run. When KE runs EvenViewer is empty.
