Asus Fx553VD - Keyboard LED backlight controls are not working # kernel-bug-reported-upstream

[R.Erol]

Hi , i'm using this laptop with it's latest bios (V303 - https://www.asus.com/Laptops/ASUS-FX553VD/HelpDesk_BIOS/ )

Kernel : 4.14.0-041400-generic x86_64

I can't control keyboard LED backlight level with it's dedicated FN keys or anything else. FN keys are recognized by Linux Mint 18.2 and Ubuntu 16.04 but pressing them have no effect.

Kernels from 4.10 to 4.14 are the same on that regard.

And also i have these errors on "inxi -F && dmesg | grep -i error"

[ 0.031175] ACPI Error: [PRT0] Namespace lookup failure, AE_ALREADY_EXISTS (20170728/dswload-378)
[ 0.040665] ACPI Error: 1 table load failures, 10 successful (20170728/tbxfload-246)
[ 0.506425] acpi PNP0A08:00: _OSC failed (AE_ERROR); disabling ASPM
[ 1.694527] RAS: Correctable Errors collector initialized.
[ 9.833145] EXT4-fs (sda2): re-mounted. Opts: errors=remount-ro

I'm not a developer but only a user. So if i opened that issue to the wrong place can you point me the correct place to open it?

Thanks.

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

Please follow the instructions on the wiki page[0]. The first step is to email the appropriate mailing list. If no response is received, then a bug may be opened on bugzilla.kernel.org.

Once this bug is reported upstream, please add the tag: 'kernel-bug-reported-upstream'.

Hi Joseph.

I already did it actually but i don't know if it is in at the right place or not.

https://bugzilla.kernel.org/show_bug.cgi?id=197889

On thing to note ; as i mentioned above this keyboard backlight issue also happened with Ubuntu provided kernels also , from 4.10 to 4.13.

And because of that i decided to install a more recent one via Ukuu to see if it helps.

So it is not only an upstream specific bug , it is also an Ubuntu kernel bug.

Is there any information i can provide here or there to ease committers work?

[Alexandre Pereira Nunes (alexandre-nunes)]

I'm not sure this is entirely related, but someone should try https://github.com/archerhush/linux-fx553vd/blob/master/kbd-backlight.patch

[R.Erol (leopard1907)]

Hi Alexandre. I don't know how to try it.

[Kai-Heng Feng (kaihengfeng)]

Can you try the daily kernel? It has some new commits on hid-asus.

[R.Erol (leopard1907)]

Hi Kai.

I installed this 4.14 kernel via Ukuu , is there a way to install this daily kernel from it or if isn't ; how can i try it?

I'm not so experienced

[Kai-Heng Feng (kaihengfeng)]

This one:

http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/linux-image-4.14.0-999-generic_4.14.0-999.201711192100_amd64.deb

[R.Erol (leopard1907)]

Kai , thank you so much!

That one works nicely , i can adjust the brightness of keyboard and turn on and off my keyboard light.

Thanks again.

One last question though ; what can i do for ACPI errors?

Unless it breaks your system, otherwise I think it’s safe to let them stay where they were.

Glad it worked for you. For anyone who has linux-stable on git (like me), if your kernel version lacks this, it's a matter of git cherry-pick 339ee3fcbdab736adbc30b7a3d675005c61a2a40 and there you go.

Btw this should work on any "gamer" laptop who have this USB keyboard:

[R.Erol (leopard1907)]

Thanks Alexandre.

When will this change merged into mainline kernel? Any guess or it will make it on 4.15 stable?
