Also, not sure if it's relevant or connected evem but some combinations (the ones for sound volume) were visible in both `acpi_listen` and `xev` output. Another thing, there's also the... Numpad key (or where reasonable vendors put the numpad key, at least), which launches an application on Windows (forgot which one it is, but it's an ASUS thing, I believe). So, I guess that would correspond to `XF86XK_Launch6` event, maybe? please attach the output of "cat /proc/interrupts" and "grep /sys/firmware/acpi/interrupts/*" both before and after pressing the hotkeys. BTW, please make sure those kernel options are enabled in your kernel, CONFIG_ASUS_LAPTOP, CONFIG_ASUS_WMI, CONFIG_ASUS_NB_WMI. I don't have the laptop with me right now, but just to make sure: What should I grep for in /sys/firmware/acpi/interrupts/* Or should I just run `grep /sys/firmware/acpi/interrupts/*` (I feel like that won't produce any output, though). Created attachment 208061 [details]
Output of `cat /proc/interrupts` before I tried any of the FN keys.
Created attachment 208071 [details]
Output of `cat /proc/interrupts` after I tried some of the non-working FN keys.
Created attachment 208081 [details]
Output of `cat /proc/interrupts` after I tried some of the working FN keys (volume ones).
Additionally, here is the output of `zgrep CONFIG_ASUS /proc/config.gz`: CONFIG_ASUS_LAPTOP=m CONFIG_ASUS_WMI=m CONFIG_ASUS_NB_WMI=m So, I assume this means that all of the kernel options you asked about are indeed present. I am still not sure what to do with `grep /sys/firmware/acpi/interrupts/*` :) (In reply to Nino Miletich from comment #0) > Created attachment 203751 [details] > Includes boot entry for systemd-boot, output of dmesg, DSDT dat and dsl, > EDID, lshw output in text and HTML, lsmod output, lspci -vvv output, and > uname -a output > > I am not entirely sure the OS can fix these problems, since it *might* be a > BIOS issue, but I am posting it here in hopes that it can be fixed by Linux, > since, same ACPI events work in Windows.

Yeah, /proc/interrupts shows that there is no ACPI events fired after pressing all of the hotkeys, which suggests that these hotkey events are not handled by ACPI IMO.

I am not 100% sure they're ACPI events, but I managed to pinpoint it to an ASUS driver called `ATKACPI` whose sole purpose is to provide the hotkey functionality (without it, they do not function on Windows either). I realise this whole thing might be more of a vendor issue than a Linux issue, though.

BTW, I actually meant "grep . /sys/firmware/acpi/interrupts/*". I have same problems with Asus ROG G752VT. OS- Slackware-current, vanilla kernel 4.4.9 And sure, all modules are loaded.

The /sys/firmware/acpi/interrupts/* files all show zeroes. There is a full dmesg as well as acpidumps in there. Just noticed that lid close does also not trigger any ACPI events, similarly /sys/firmware/acpi/interrupts/* stays zero. Let me know if there is anything that can be tried, or if you need SSH access. Bug 115021 turns out to have a different cause. Nino, can you attach the output of the acpidump command? I am interested in the contents of the ECDT table, but you have only included the DSDT. Please boot with: acpi.trace_state=enable dyndbg="file ec.c +p" Your kernel must have CONFIG_DYNAMIC_DEBUG=y for dyndbg="...", but this is the case for Arch Linux kernels. But the former requires CONFIG_ACPI_DEBUG=y which is not enabled in the Arch kernel. Can you build the kernel with said options enabled? Hi,
Please give this patch a try:

Hi, Peter & Nino I'll leave this bug as platform specific issue. If any help you want from ACPI developers, please feel free to re-assign it to ACPI category. Thanks Lv Hi,
I confirm the same behaviour on Linux Mint 18.

Pedro, I think you should attach to your own, *new* bug report, all possibly relevant files for the 4.10.5 kernel . See my bug #194719 for such listing. Hijacking bug report of other is not helpful. Be sure to include the BIOS-related files. Then add link to your bug number from here.

I have been informed that there are people (Chris Chiu and Daniel Drake) working on ASUS ROG models, and their patches are already slated to be released with kernel 4.12: https://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid.git/log/?h=for-4.12/asus Unfortunately I'm not able to apply those patches by myself. It would be great if some of you Linux people affected by "ASUS G752VS - Touchpad and Fn keys" problem can test mentioned patches and enter in contact with Chris and Daniel. Yes, the hot keys should be fixed on these models with the mentioned patches. I think this bug can be closed. If anyone wants to post the contents of /proc/bus/input/devices I will double check that we have the right device IDs included. Created attachment 255647 [details]

You could try modifying the code to add it and see if it works. See commit "HID: asus: support Republic of Gamers special keys". You need to add the ID to the ignore list in hid-core and then add it to the supported device list in hid-asus. Maybe I make something wrong, but nothing happiness.

New /proc/bus/input/devices with Asus ROG patch
Sounds like we will need a different type of fix for your keyboard then. The way we fixed it for the other models was to use the hid debugfs interface to see what events are generated when those keys are pressed. I'm not very advanced, but if you say how I can use hid defugfs for see and write you required events of keyboard.... One year ago I buy ROG 752VT, and can't normally work. Many users of ASUS too have similar problems. Created attachment 255667 [details]

Run "cat /sys/kernel/debug/hid/ID_of_ASUS_ROG_g752vt_keyboard/events" Now for every key press you should get some output. Press and release one of the unsupported hotkeys and note which lines of output correspond to that, and paste them here. Nothing. Only show 'p' for Fn+F8(display) ^[[25~ for Fn+F10(mute) ^[[26~ for Fn+F11(volume down) Strange then no output for Fn+F12(volume up), 'cause this work in X and really Volume UP Maybe i need compile in kernel additional driver? Need .config and lsmod? Hello Daniel Drake, Is it possible to apply a PATCH to kernel 4.10 that will be used in Ubuntu 17.04 or to kernel 4.8 used by Ubuntu LTS so I could have keyboard in ASUS G752VS? Probably, the question was nonsense. At least is presumptuous, I admit. Although those versions will have working nvidia drivers sooner or they have already, something I'm very interested in using. Note: I haven't built kernel 4.12, ergo don't know if anything works by now.
