Bug still exists in  4.10.0-041000rc8-generic #201702121731

After digging a bit, I understood that Asus is using their "Aura" software to control keyboard backlight, so it may change colors etc. Is there any possible linux module for "Aura"?

Exactly the same issues here on an ASUS GL753VD laptop running Fedora 25 with kernel 4.9.8. Seems to be the same keyboard hardware (0b05:1854). No control of keyboard backlight (only airplanemode light is found) and the beforementioned function keys do not work.

Hi guys,

have you tried the patch mentioned in [1]? It fixed my problem with brightness keys, although other keys like volume and wireless were working before.

Also, can you guys add a dmesg output? Thanks.

Hi guys,

I couldn't see anything obvious in your dmesg files. However, as the mentioned patch touches the currently active display, this may not be shown in dmesg.

Can you guys please test the attached patch, or just test 4.10-rc8?

Thanks

lshw output for Asus FX53VD/GL553VD

I am also still getting this issue of no keyboard FN functionality working except for volume buttons. I added my lshw output for my FX53VD (which identifies itself in the BIOS as a GL553VD, must be same internals). This is on kernel 4.11rc2. In addition, I recieve this error on startup regarding ACPI:

[    0.030577] ACPI Error: [PRT0] Namespace lookup failure, AE_ALREADY_EXISTS (20170119/dswload-378)

Not sure if this is related or not. I can get any other info as needed if it would help.

I have an FX553VD. This laptop comes preinstalled with Endless OS(a Linux distro) and not Windows. (I got rid of it and installed Ubuntu on day one though). I compiled the Endless OS kernel from https://github.com/endlessm/linux and installed it. Most the function keys(sleep, airplane mode, brightness, touchpad, sound) are now working. I haven't investigated what changes they have made to the source yet. The keyboard backlight control doesn't work however. The keypress is identified and GNOME shows a notification, but the keyboard backlight can't be dimmed/increased. The folder /sys/class/leds/asus::kbd_backlight/ is missing. The script that is run on pressing Fn+F3/F4 uses a file in that folder to control the keyboard backlight.

Collection of Patches from EndlessOS

Here are the differences I've noted from comparing 4.10.10 to EndlessOS's. I was able to successfully compile and install a kernel with these patches on my Arch install. I'm not sure if I'm allowed to provide these patches or not to officially be included as I did not write them and all credit goes to the Endless team. I also noticed that the keyboard backlight behavior is the same as the previous poster's.

Ok, so those patches are broken because I messed up creating the tar file, however, here is the Github commit that added support just 7 days ago for the FN keys

Fixed collection of patches from EndlessOS

Thanks John! Patched the latest Fedora 25 kernel (4.10.10-200) on my ASUS GL753VD using these patches. Function keys work now, but unfortunately no led control for the keyboard yet.... The USB identifiers in de code seem to match though.

Anyone an idea if Aura (which these Strix keyboards seem to use) is already available in another way ?

I got the function keys and keyboard backlight brightness control working. It seems you need to set a quirk flag to enable the keyboard backlight dimming with the provided patches. I ended up changing the code to force initialization of the keyboard backlight altering code, but this is nog the clean way. If I have some time I will try to get this to work the correct way by setting the quirk flag on module load (should be 0x10 or 16 decimal, so quirk=0x10 as argument to the module.d config file). So basic function is there, now only to find the code for setting the colors and I'm a happy camper ...

I modified a line in hid-asus.c, from
#define KEYBOARD_QUIRKS	(QUIRK_FIX_NOTEBOOK_REPORT | QUIRK_NO_INIT_REPORTS)
to
#define KEYBOARD_QUIRKS	(QUIRK_USE_KBD_BACKLIGHT | QUIRK_FIX_NOTEBOOK_REPORT | QUIRK_NO_INIT_REPORTS)

The keyboard backlight still doesn't work on my FX553VD.

You also need to add the QUIRK flags to the hid_device_id structure for USB_DEVICE_ID_ASUSTEK_ROG_KEYBOARD1. Better solution is to add is to the modules.d config for module load (also need to recreate ramdisk as I guess this driver is loaded from ramdisk first).

There is another check too which I disabled, the one that checks for the SUPPORT_KBD_BACKLIGHT flag during init. I have created a new patch with more logging so I can build a kernel to see what all flags are and which are tested to see where things get blocked. Just need some time to do the debugging ...

Thanks Martijn! I can confirm that the keyboard backlight is now working and controllable on the FX553-VD.  

This laptop doesn't support different colored backlights, just off or three levels of brightness, all of which are functional.

That's great news, can you share what you did exactly to get this working ?

Patches to get keyboard backlight function working

This patch is to be applied on hid-asus.c -- use the one from the EndlessOS tree, or the modified hid-asus.c from John's patch

I did exactly what Martijn said, a few changes in hid-asus.c. I've attached it as a patch in my previous post. I'm using the EndlessOS kernel, but it should work if you've applied already applied John's patches from the EndlessOS tree.

@Karthik, thanks for your answer.

I have done some debugging, reinstated all checks with additional logging and I could not set the Quirk flag in any dynamic way like as kernel boot argument (usbhid.quirks) or module argument to hid-asus. The only way is like Karthik did, and that is to add the quirk flag for the USB_DEVICE_ID_ASUSTEK_ROG_KEYBOARD1 entry (which is 0 in the original patch).

I don't know if changing it this way will break something (why was this flag not set for this keyboard type in the first place?) and unfortunately i'm no USB kernel module guru in any way.

So as it stands this is currently the only way to get this working. I will tidy up and make a patch as I used on my fedora 25 install that can be used as a drop-in for the rpmbuild process later.

Hello, 

I have also asusFX553VD and i m facing same problem. After many search, someone send me this page link. Please make a simple command list, so I can able to install those patches in my ubuntu 16.04 kernal. 

I tried, but maybe some mistake i didn't patch it. 
Thank you.

I have applied 7 patches: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/drivers/hid/hid-asus.c (in the reverse order, so first "HID: asus: support Republic of Gamers special keys", "HID: asus: fix and generalize ambiguous preprocessor macros" secondly, etc.

I successfully booted up then with the kernel, but the keyboard function keys still do not work. @Karthik's patch doesn't seem work anymore with the last kernel.

Running ArchLinux.

Now, finally.... new kernel this this bug is fixed..98%. Still keyboard back-light is not changing. Rest of all key working fine.

I can confirm that on my FX53VD (different from the FX553VD) the FN keys seem to function properly except the keyboard backlight never changes. However, while running GNOME there is an icon that pops up indicating that the keyboard backlight is trying to be changed, or something similar to that nature? However, the backlight itself never changes.

Yes... @johnHertzog - 

Backlight is not changing, and just popup is appearing. 
No acpi_listion on F3, F4. 

Backlight eating battery power and my battery hardly working for 1H 48Min. same happening with your battery ?

I haven't tested the patch I posted earlier on 4.12. It works on 4.10 however.

Regarding battery life, I highly doubt its the backlight. I get 3~4 hours with the keyboard backlight on. Maybe your discrete GPU is running all the time? Running powertop should give you an idea as to what is draining your battery.

Could you tell if that patch with the 4.10 let all FN keys do work in the OS? Are you still using this version? Are all your FN keys working (if so, how did you make them working)? What's your output of `uname -r` (which precise kernel release did you use to make this patch?)?

My FX553-VD came with EndlessOS preinstalled, but I got rid of it the day I bought it. So I compiled the kernel from their tree(https://github.com/endlessm/linux) and all the function keys except keyboard backlight worked immediately. At the time I cloned their source, it was version 4.10.

For keyboard backlight, I've attached a patch in one of my earlier posts in this thread based on what Martijn said. 

I'm still using that kernel, haven't got around to updating to a newer kernel.

Is there a way to get that 4.10 kernel to patch and compile it? Is it equivalent to the standard Linux kernel?

The EndlessOS kernel has some changes made to hid-asus.c(atleast) which enable the function keys. This is the kernel I'm using.

OR, you could patch a regular 4.10 kernel. John uploaded a patch in this thread with the changes: https://bugzilla.kernel.org/attachment.cgi?id=255913


Either way, after that, you'll have to apply this patch: https://bugzilla.kernel.org/attachment.cgi?id=256023&action=diff.


> Is there a way to get that 4.10 kernel to patch and compile it?
You can pass `--branch v4.10` as an argument to `git clone` when downloading the source. 
If you are talking about the 4.10 version of the EndlessOS kernel, I am not sure. Perhaps you could clone their repo, and use git checkout to get to the kernel's state on April 17th(which is when I compiled the kernel).

My system hardly run 1.48H without NVIDIA GPU. And when I enabled, generally GPU is taking around ~300MB. I don't know what is problem with it... (i m using netbeans n some development apps). 

Now, for powertop... when i calibrate system using powertop, on that time i get 1.48H. without it 1.30H max.

@karthik suggest me more so i can resolve it.. or any other link available for discussion for battery...  (this thred for backlight and Fn key)     

Thank you !

Oh, I forgot to reply. It worked, thanks.

Please stop annoying people with off-topic requests. There are a lot of relevant guides on the internet for what you're asking.

Diff from original 4.12 kernel to make backlight and its keys working on GL553VE

Finally, almost all keys are working for my GL553VE on 4.12 kernel from stock.

Backlight/F3/F4 were still disabled, however, I managed to get them working with the given diff on 4.12 kernel (based on Karthik Karanth patch). There is no way to change color, but the backlight and its keys are now working.

This diff is purely guess-based, so it needs to be cleaned up/reviewed by a experienced developer. At least it is working.

I've tried to apply this: https://bugzilla.kernel.org/attachment.cgi?id=257399 on a 4.12.3 base kernel, but the patch failed. Why?

Maybe because of changes in 4.12.3 kernel? I pathced the 4.12.0 one, there are some changes afterwards.

Try ignoring whitespace with the --ignore-whitespace flag. I had to do that to get 4.12.2 to patch, haven't tried 4.12.3 yet.

I can confirm that Cabalbl4 (i-vohmin)'s  (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1662316/comments/11) pre-compiled 4.12.0_custom kernel makes all the F1 to F12 keys work on my ASUS GL753 VD.

So, the patch still works with the latest 4.14.5 kernel and is necessary to make backlight keys work. Would this patch break other keyboards? What is preventing this from being submitted upstream?

Just to let you know that the backlight keys works ok with the 4.15 kernels, without any patches. Running it on my ROG GL753VD.

Unfortunately for me does not work. I have GL553VW with last 4.15 (Linux apeelme-GL553VW 4.15.0-041500-generic #201801282230 SMP Sun Jan 28 22:31:30 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux) and does not work except the volume keys.
Missing /sys/class/leds/asus::kbd_backlight and acpi_listen can not "hear" anything on press Fn+F3/F4/F5/F6 etc.!

apeelme

Kernel 4.15 enables keyboard backlight control for me (GL553VE). No more kernel patching needed.

I understand, but GL553VW not working!!!!

Have you tried applying my patch to kernel?
It kind of force-loads Asus quirks regardless to any conditions.
If it solves issues for you, then loading conditions need to be adjusted
If not, seems that your hardware differs a lot from my VE model

Im not. Sorry for my question...but im not build every day....
build own kernel procedure (ubuntu 16.04.3 LTS):

1. apt-get source linux-image-$(uname -r)
2. apt-get build-dep linux-image-$(uname -r)
3. chmod a+x debian/rules
   chmod a+x debian/scripts/*
   chmod a+x debian/scripts/misc/*
   fakeroot debian/rules clean
   fakeroot debian/rules editconfigs
4. patching files
5. fakeroot debian/rules clean
6. fakeroot debian/rules binary-headers binary-generic binary-perarch
7. and install sudo dpkg -i 3 deb files?

Ok i make a fast test, modified in drivers/hid/hid-ids.h line #183:
-#define USB_DEVICE_ID_ASUSTEK_ROG_KEYBOARD2 0x1837
+#define USB_DEVICE_ID_ASUSTEK_ROG_KEYBOARD2 0x8176

build, and install *.deb's, reboot and worked all Fn buttons!!!!!!!!

The keyboard backlight works amazingly on my FX53VD (which identifies to Linux as a GL553VD) with 4.15.3

Yes! After 4.15 it started to work like a charm, out of the "box"  :-)

Linux shivangpatel 4.15.3-041503-generic #201802120730 SMP Mon Feb 12 07:31:14 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux


I am also confirming that, my asus FX553VD working fine with 4.15. If you found any problem related to display, then you need to update nvidia drivers and install new one.

Thanks.

4.15.3 and 4.16-rc1 also does not work for me!!!! (GL553VW)

Serious? Who should write a letter to move the story because it has the solution??????

Like shivangpatel, i recently buy an ASUS FX553VD. And it working fine under v4.15.4.

Hello everybody. I hope this post is still not dead. I have Asus-FX553VD and i am new to Linux.

I also have a problem with keyboard backlight. I don't understand how to apply a patch, could someone help me please?

Here's uname-r

4.17.0-041700rc6-generic


Only on that kernel my touchpad is working and i have no problems with gpu's. 

My FN keys also don't work (except of volume FN+F1, FN+F2, FN+F3).

Hi.
Opensuse tumbleweed. Kernel 4.18.5-1-default
KDE 5.13.4
module asus-nb-wmi - load
ASUS ux430ua

 Fn+F3 & Fn+F4 - don't work backlighte keyboard.
Fn+10/11/12 - volume control - don't work.
Monitor backlight working fine by using menu slider.

if i used
>echo 0(1,2,3) >>
>/sys/devices/platform/asus-nb-wmi/leds/asus\:\:kbd_backlight/brightness
 - can control backlight

is start notebook with KDE Neon User Edition 20180823 live image (kernel 4.15, Plasma 5.13) - all work

I don't think drivers/platform is the appropriate place for this one.  The reported issues with the GL553VE are nearly identical to what I experience on a GL502VE.

My observations:
There are almost never any WMI events on this system.  The only time I see WMI events is when unplugging/plugging AC.  (The system is sending some unrecognized event codes in the kernel, but KDE seems to still recognize AC state properly.)

Rather than use WMI, it appears that Asus ROG laptops with per-key RGB lighting are using what is effectively a USB-attached ROG Claymore ( https://www.asus.com/us/Keyboards-Mice/ROG-Claymore/ )

Presses of the unrecognized Fn keys ARE viewable in /dev/hidraw3 or /dev/usb/hiddev0 - they're coming in as nonstandard HID reports instead of via WMI events.

Control of RGB backlight via Armoury Crate on Windows when Wireshark is running using USBPcap shows traffic to the compound USB device.

I'll attach wireshark traces and kernel logs later this week.  This is a work in progress, I just discovered this a few minutes ago and came across this bug report when searching for info on the Claymore and Linux.
