[Solved] Laptop keyboard not working in any distro

[Rinkeby]

Hi all! New here.

So after many years of fedora, I am Debian for my laptop. However, my laptop that works well, does not have working keyboard. And just need your help!

Strange part is that it works in Grub. But after that. No matter what kernel I use, even up to experimental kernel in Manjaro. It still doesn't work. I tried debian 10, but wont start instead.

I tried i8042.reset i8042.unlock i8042.nopnp i8042... many of them, The only one that works is i8042.dumbkbd. However. they keys lags a lot, and if i press for example F, it get FFFFFFFFFFFFFFFFFFF.

I also tried different xorg set ups, but might have done it wrongly.

So, any log you need I will provide, but unsure what you want. The computer is an oddball named Cepter

Any help would be wonderful!

[Rinkeby]

OK guys. I guess you are a bit bored answering keyboard problems.

However. I solved it by downgrading kernel to 5.10.209-2 in manjaro.

However. Thats a long way back. And is this a clue what can be wrong in the never kernels?

Or I guess my real question is.how do I downgrade that far in Debian 12?

Hello,

Can you report your general hardware/software configuration ? You can use the following command (the inxi program must be installed):

Hello,

It looks like you are using an AMD Ryzen:

There is an earlier discussion on a similar topic in the Arch forum:

• Index » Kernel & Hardware » [Solved] Keyboard problem - Thinkbook 14+ ARA

According to this post:

• #15

  It's a weird design choice instead of a bug:
  They made the keyboard IRQ active-low instead of the conventional active-high found in almost all other computers.
  The kernel decided to override this, which made the keyboard controller non-functional.

A kernel patch has been proposed:

• #29

  It seems the IRQ issues are being upstreamed in here https://lore.kernel.org/all/20220712020 … gmail.com/ by just checking whether it's ZEN CPU or not ?

This is the code of the proposed kernel patch:

• [PATCH v6] ACPI: skip IRQ override on AMD Zen platforms

  Code: Select all

  IRQ override isn't needed on modern AMD Zen systems.
  There's an active low keyboard IRQ on AMD Ryzen 6000 and it will stay
  this way on newer platforms. This IRQ override breaks keyboards for
  almost all Ryzen 6000 laptops currently on the market.
  
  Skip this IRQ override for all AMD Zen platforms because this IRQ
  override is supposed to be a workaround for buggy ACPI DSDT and we can't
  have a long list of all future AMD CPUs/Laptops in the kernel code.
  If a device with buggy ACPI DSDT shows up, a separated list containing
  just them should be created.

This patch is not included in the linux kernel currently released with Debian Stable:

• https://sources.debian.org/src/linux/6.1.67-1/drivers/acpi/resource.c/#L561

The patch is included in newer kernels available from stable-backports repositories; i.e.:

• https://sources.debian.org/src/linux/6.5.10-1~bpo12%2B1/drivers/acpi/resource.c/#L593

Therefore, you can try installing a newer kernel from the stable backports repositories [1].

Hope this helps. Please, let me know.

hey @Aki

I tried linux-image-6.5.0-0.deb12.1-amd64 from debian backports. But it did not work. However, 6.5 is a pretty high number. But all and all, did I understand your directions correctly?

The kernel 6.5 includes the aforementioned patch.

Sorry for asking: did you boot with the newer kernel ?

Can you report the output of the following commands after booting with kernel 6.5 (using an external keyboard) ?

No worries. Sometimes you are lost in manuals, sometimes you make mistakes. But not this time. Though I installed debian 11.9 to upgrade it to 12 so I could keep the working kernel. If it matters

Hello,

Thank you for your patience.

Can you confirm that the embedded keyboard does not work with kernel 6.5?

Can you confirm that you used an external keyboard to get started and have the log from the previous post with kernel 6.5 ?

Have you tested the keyboard on a virtual console (text console), i.e. booting into rescue mode from grub ?

Since your motherboard firmware is really brand new (date: 10/12/2023), I would test the latest kernel version available for Debian Unstable. You can download and install it with the following commands (as root user):

Code: Select all

wget http://ftp.us.debian.org/debian/pool/main/l/linux-signed-amd64/linux-image-6.7.7-amd64_6.7.7-1_amd64.deb
dpkg -i linux-image-6.7.7-amd64_6.7.7-1_amd64.deb

These commands will simply add it to the already installed kernels, so that you can test it with your keyboard (after restarting the operating system).

[Rinkeby]

Hi,

Yes, I can confirm this. However, now when i tried secure mode from grub. Grub is now also "broken" in terms of keyboard.

And the kernel you sent me, just like in manjaro with higher number, makes the keyboard work. BUT, when i press a key, lets say A this time, i get AAAAAAAAAAAAAAAAA. Same with i8042.dumbkbd.

I can now also ad something mysterious (typically me debugging). And that is that both Manjaros Grub and Debians Grub got broken from booting to secure boot. Very strange. So, then I booted up windows. Rebooted. And then Grub worked normally again. So might this all be dual boot thing? UEFI? Perhaps install debian clean as solo OS without Grub?

[Aki]

Is windows completely shut down when starting Debian(i.e. not suspended and not hibernated) ?

Is Widows fast boot disabled ?

[Rinkeby]

I been extra careful with this. So no fast boot. No secure boot for windows, and no hibernation. And it seems strange that windows would effect Grub. Then Live CDs would not work or anything. However, the old kernel still works well. So there is no stress with this from your side.

Hello,

Even if it is a different brand, also this kernel bug report is relevant to your issue:

• Multiple AMD Lenovo laptops keyboards do not work under Linux (including V14/V15 G14 AMN)

The bug is reported as "fixed" with this patch:

• x86/i8259: Skip probing when ACPI/MADT advertises PCAT compatibility

This patch is included in the kernel 6.7.7 (currently in Debian Unstable) I suggested you to test:

• https://codesearch.debian.net/show?file=linux_6.7.7-1%2Farch%2Fx86%2Fkernel%2Facpi%2Fboot.c&line=153

I would rule out the possibility that your keyboard was not working properly with kernel 6.7.7 due to a previous malfunction (as you reported that grub was also affected at some point).

You can also temporarily add the kernel parameter "i8042.debug=1" with different kernels to collect logs about the i8042 keyboard and mouse controller. After adding it, you can filter system logs with the following command (as root user):

Code: Select all

script i8042.log
journalctl -b --no-pager -g i8042
exit

You can report logs in one the following ways:

• paste them into the Debian Pastezone service (https://paste.debian.net) and report the URL/link of the paste in a follow-up message

• attaching the logs to a follow-up forum message as a compressed zip or gz file

• paste logs into the body of a follow-up message between code tags (if they fit the size of a forum message)

Hope this helps.

Hi,

Yes thank you for your help. Very interesting to meet such support. And I will do what you told a bit later. Meanwhile I will do some extra research on my own, and perhaps post new finds here?
(And as the older kernel works so well, I just wish there was a way to screen the differences between 5.10. and 6.1 for example)

Thanks again. I think we were close, but some step more.

[Aki]

Hello,

And as the older kernel works so well, I just wish there was a way to screen the differences between 5.10. and 6.1 for example

You can try bisecting kernel commits using git:

• https://www.kernel.org/

You will need to set up a kernel build environment and rebuild/test kernels (so adequate time and cpu / disk resources are required) according to selected commits, until you identify a single or a few commits that, if compiled/not compiled, make the issue appear/disappear:

• Kernel documentation - Bisecting a bug

• Debian Wiki - BisectDebian

It is time consuming. It can also be tricky to identify a single affecting commit between major kernel versions (i.e. 5.10 -> 6.0) due to the high number of commits or if it is not caused by a single commit.

[Rinkeby]

While looking into your direction. here is the log difference between 6.7.7 and 5.10.

[panpan]

Check this solution: https://bbs.archlinux.org/viewtopic.php?id=255362

Solution:
For unknown reasons the PS/2 controller can't be found immediately when starting (not restarting) . The solution is to add the following lines to grub:

i8042.notimeout i8042.nopnp

In addition, as described above, the i8042 module has to be added to mkinitcpio.conf.

[Rinkeby]

Hey @panpan

Not working either. Looked promising.
