It is usually a good idea to at least Cc the relevant linux mailinglist on questions like this.

The keyboard has a physical switch for "Windows" and "Mac" modes, however in both cases the kernel recognizes it as an Apple keyboard and loads the "hid-apple" module. However it does *not* recognize the 'Fn' key and disables it. But the keyboard has one and I have to enable it manually either via: > > # as root: > echo 2 > /sys/module/hid_apple/parameters/fnmode > > or permanently: > > options hid_apple fnmode=2 > in /etc/modprobe.d/hid_apple.conf > > Without this, I cannot use the Function-keys, they will always be used as Multimedia-keys, regardless if you press Fn + F1 or not. > > Here's the relevant dmesg output when i plug the keyboard in. > > [ 6.234069] apple 0003:05AC:024F.0004: input,hidraw3: USB HID v1.11 Keyboard [Keychron Keychron C1] on usb-0000:06:00.4-1.2.1.2/input0 > [ 6.234261] apple 0003:05AC:024F.0005: Fn key not found (Apple Wireless Keyboard clone?), disabling Fn key handling > [ 6.294181] apple 0003:05AC:024F.0005: input,hidraw4: USB HID v1.11 Keyboard [Keychron Keychron C1] on usb-0000:06:00.4-1.2.1.2/input1 Ok, so the keyboard presents itself as 2 interfaces. and the "Fn key not found" message is only being printed for the second interface. So I guess that the trouble F1-F12 keys are actually coming out of the first interface (the 0003:05AC:024F.0004 device above). What my patch does it completely disables the fnmode handling, similar to setting the fnmode parameter to 0, but unlike my (Maxxter KB-BT-001 Bluetooth keyboard) "clone" your keyboard does actually advertise a Mac style Fn key in its descriptors, at least for the first interface so it is treated as a standard Mac keyboard where the non Fn behavior of the F-keys is to send the multimedia events. Normally pressing Fn + F1 - F-12 should then result in the kernel actually sending F1-F12 and setting fnmode=2 should just invert when you need to press Fn. Basically the way the actual mac keyboards work is the simply always send F1 - F12 events and a separate Fn event and leave it up to the OS to translate this to either plain F1 - F12 or to the multimedia codes. Where as normal keyboards handle the Fn press internally and actually send different "scancodes" over the wire to the computer when Fn + F1 - F12 is pressed. But if I understand you correctly then the Fn translation hid-apple is doing to make things work as expected with Mac keyboards is not working for you, IOW with fnmode=1 pressing Fn + F1 does not result in F1 being send, correct ? This means that your keyboard behaves more like a normal keyboard instead of as an apple keyboard. I also wonder if the Fn key sends any events at all (or if it is fully handled internally)... > I have no idea how to fix this, but I can provide additional information if needed.

Here's the evemu-record output for the first device. I pressed F1, Fn, and Fn+F1 as requested, however only the F1 key produced output. Fn did nothing and Fn+F1 decreased the display backlight but didn't produce output.

Can you try (temporarily) disabling secure boot in your BIOS, that should fix things (otherwise there are other ways to get the descriptors but in my experience this way is the easiest) >> Also please as root run: >> >> sudo evemu-record >> >> And then select the device belonging to your keyboard and press F1, Fn and Fn + F1, >> please repeat this for all input devices belonging to your keyboard and then >> copy and paste the output of each run into your next email. > > Here's the evemu-record output for the first device. I pressed F1, Fn, and Fn+F1 as requested, however only the F1 key produced output. Fn did nothing and Fn+F1 decreased the display backlight but didn't produce output.

Which means that your keyboard really should just be handled by a the standard hid-input driver rather then being handled by the special hid-apple driver. Now if only it would have not "hijacked" Apple's USB vendor and product id and would just have used their own then everything would just work. IOW this is another clone like the Maxxter kbd I added, but the current clone-detection code is not detecting it (at least not for the first of the usb interfaces which it has). Just to make sure I'm not missing anything, can you redo the evemu-record tests with the switch set to mac mode. And when you gather the rdesc files can you do that twice too, once in windows mode and once in mac mode ? Please unplug and replug the keyboard after changing the switch to make sure that Linux sees the changed descriptors (assuming they change at all).

At least for a Windows-like (i.e. non-Apple-) mode of operation that would be my expected default mode anyways. Thank you for the logs and sorry for being so slow to respond. So looking at your evemu-record output, the keyboard is actually behaving like a real Apple keyboard when put in Mac. mode. This means that you should be able to send a "F1" keypress without specifying any module parameter at all by pressing "Fn + F1" when the keyboard is in Mac mode. IOW in Mac mode everything should work fine, except that you may not like the default behavior of F1-F12 being to send "multi-media" key events instead of just plain "F1" - "F12" (and that you can change with the fnmode=2 module parameter). Since the keyboard is also using an Apple vendor- + product-id code when in PC mode, things won't work as well in PC mode though since then the "Fn" key likely does not actually send an event to the machine to which the kbd is connected, causing the keys to be stuck in "multi-media" mode regardless of the Fn key state since when Fn is not pressed this is the default behavior and when Fn is pressed then the key-press gets reported on the second interface / device as a multi-media key-press. This is really all the fault of the kbd-manufacturer, it should really use different (non Apple) vendor- + product-ids when in PC mode. So the reason why I asked for the descriptors is to see if there was some way to distuingish this keyboard from real Apple keyboards, but I've already found a way to do that: > # Properties: > N: Keychron Keychron C1 The "Keychron Keychron C1" here comes from the USB device strings; and we can use that to tell that we are dealing with this Apple clone. So now the question becomes what to do with this info though. As I already said, I believe that in "Mac" mode all is working as it should. The problem is the "PC mode", the only thing which I can come up with is to make fnmode=2 the default on this keyboard, since that will also work in Mac mode (albeit different as on real Mac keyboards) while also working in PC mode. Does anyone (including you, Bastian) has any opinion on making fnmode=2 the default on this keyboard model ? Regards, Hans ^ permalink raw reply [flat|nested] 11+ messages in thread

If i understand you correctly, you're saying you cannot make the fnmode depend on the Mac- or PC-mode that the keyboard is currently running on? I mean that would be of course the best solution, but if that is not possible I'd prefer the fnmode=2 switched on by default as this is not a Mac keyboard AND this is not an Apple operating system.
