Keyboard and Touchpad Not Working in New Lenovo V15 Gen4 Laptop

[Pradip Kumar Das]

[Impact]

Keyboard and touchpad doesn't work on some recent systems, and also s2idle is broken.

[Fix]

Two upstream commits.

128b0c9781c9f26 x86/i8259: Skip probing when ACPI/MADT advertises PCAT compatibility
3bde7ec13c97144 platform/x86: Add s2idle quirk for more Lenovo laptops

[Test case]

boot a fixed kernel and test that input and s2idle works.

[Where problems could occur]

A buggy bios could maybe advertise a system being PCAT compatible when it's not, though in such a case it might have been already caught before.

Hello.

Ubuntu 22.04.3 with (later upgraded to kernel 6.2.0-32-generic) was installed in rewly purchased LENOVO V15 GEN4 AMN (AMD Ryzen 5 7520u) laptop and it was noticed that keyboard, touchpad and microphone are not working. The keyboard and touchpad work fine in BIOS setup and till GRUB (command line). It was found that when external devices such as keyboard, mouse and microphone are connected through USB and 3.5 jack, respectively, these work just fine. To confirm these are not hardware problems, Microsoft Windows 11 (Home) was installed in another disk partition and observed all these working alright. Hence a bug is being reported to draw attention of the concerned team and I request them to refer this issue and do the needful at the earliest.

Regards,
Pradip Kumar Das

Status changed to 'Confirmed' because the bug affects multiple users.

[Danielle Satterfield (dsatterfield)]

I am fairly certain this also affects the Lenovo V14 G4 AMN running the same 7520u processor. Symptoms are the same.

[Serge (serge1278345)]

Lenovo V15 G4 AMN (82YU00UCRA) - AMD Ryzen 3 7320U - same problem.

[Morty Williams (user307513)]

Tried all solutions. Nothing helps at this point. This laptop is quite fresh, I think there will be even more requests.

Same touchpad + mouse issue here. When I'm online I must alternate plugging mouse and keyboard in order to navigate

Same issue with Lenovo V15 Gen 4 AMN, AMD Ryzen 5 7520u.
Fix Released? where?

[Endre Olah (endreolah68)]

Same issue on Lenovo Ideapad Slim 3 AMD Ryzen 5 7520u. How this above fix will be issued? Any option to be able to test it? Thanks

[Serge (serge1278345)]

Wtf? Why status "Fix Released"? How it works?

[Endre Olah (endreolah68)]

I guess, Rayen was just marked this as fixed, but actually it is not. Can this bug be reopened? I have checked that who can make this status adjustment and it seems that anybody can do it, but unfortunately you just could elevate the status and you cannot put it back to a previous status. This issue might never be fixed, if somebody just say "Fixed" without real confirmation.

[Pradip Kumar Das (pradipkumardas)]

Hello Endre,

I have written email to Rayen to consider this bug status change and requested to let us know about the solution.

Regards,
Pradip Kumar Das

[Endre Olah (endreolah68)]

Hi Pradip,

if Rayen is not in any team to fix the issue, how can he decide if it is solved or not? I think there is an issue how the workflows are running.

There should be a solution explained and then confirmed by at least a few affected users or by time if at least one confirmation is given that the fix is working.

Now somebody is saying the fix issued, but nobody else knows what is that and how to apply. My computer is still not having the fix. I cannot find such a kernel, called linux.signed-hwe-6.2 or I am looking for it at a wrong place.

But thanks for trying to get this to the right direction.

Kind regards

       Endre

[Rayen Majoul (re0syst)]

I accidentally changed the status and can't revert it back to 'confirmed.'

[Rayen Majoul (re0syst)]

btw this problem persists even in the latest kernel version 6.5 on Ubuntu 23.10

[Endre Olah (endreolah68)]

Hi Pradip,

as you have issued this bug report, could you reset it to confirmed somehow or issue a new bug report, please?

There many people who have effected by this bug. I think most of the AMD 6000 and 7000 series laptops from some specific manufacturer. Lot of discussion forums having the same issue mentioned, but no solution so far.

Thanks

      Endre

[Pradip Kumar Das (pradipkumardas)]

As Rayen had changed the bug status from "Confirmed" to "Fix Released" by mistake, I just changed it back to the previous one, and hope that kernel team will now pay attention, work and release an appropriate fix for the above mentioned issues at the earliest.

[Endre Olah (endreolah68)]

Thanks, Pradip! You are great! I hope the fix will come soon. I like Linux, so I would like to use it.

Have a nice day!

[Endre Olah (endreolah68)]

This what I saw. External keyboard and mouse attached and working. But internal keyboard and touch pad does not.

Built in microphone also does not work.

[Pradip Kumar Das (pradipkumardas)]

Exactly Endre. These are the major problems. Request to kernel team will be to address these three problems on priority.

In addition to that there is one more problem that I might not have mentioned earlier and that is the issue related to system Suspend functionality. In my LENOVO V15 GEN4 AMN (AMD Ryzen 5 7520u) laptop, system does not enter into standby mode when physical power button is pressed even though the button is mapped to suspend mode done through Settings-->Power-->Power Button Behavior. This is inconveinent especially when I wish to talk for a shorter distance with just laptop lid closed, but cannot do because then the system gets unstable. So, only option left to me is to move around by keeping the laptop lid open.

So, it should also be checked by others if they are experiencing the same behavior. And if so, then it could also be another concern that the kernel team might be interested to look into.

[Rayen Majoul (re0syst)]

Does anyone know of a Linux distribution with the latest kernel version 6.6?

[Endre Olah (endreolah68)]

According to the Kernel list 6.5 is the latest available/official, but even that was not solving the problem.

[Endre Olah (endreolah68)]

On 23.04 the microphone is working already. I have tried to upgrade yesterday to 23.10, but the install windows are not appearing properly, so cannot see the steps. (With the updater tool the upgrade did not appear yet.)

The other windows on the live DVD, like Libre Office, or the settings windows work properly.

[Kyrylo Budnyk (kirry36)]

I have this laptop (V15 AMN on R3 7320U / 16G RAM), have built 6.5.7 kernel with all I2C drivers.
Uploading several of dmesg dump files with different parameters and xinput dump file.

Hope we will see a fix soon.

Also can notice, "extra buttons" kind of working, even can setup screen brightness. Also keyboard is responding to Numpad, Caps Lock states (duplicating it from USB keyboard)

[Endre Olah (endreolah68)]

Ubuntu 23.10 not fixed the issue yet. Kernel 6.5.0

[Pradip Kumar Das (pradipkumardas)]

Thanks Endre for the update, but that kernel v6.5.x was my hope to get these issues addressed. How long can we just be waiting for without any communication from the kernel development team? One option is just wait for indefinite period of time to hear from them or to take decision to invest once more in another computer which is matter of hefty amount money and making me feel low about these whole experience we are going through.

[Endre Olah (endreolah68)]

I partially agree with you, Pradip. It is weird that such input methods are not working on all laptops under Linux. But I can imagine that too many different hardware are on the market, where it is hard to develop to all at once and maybe the developers does not have the chance to test on all of them. So let's be patient for a while. These hardwares are pretty new, so the fix will come, I am sure.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[[e-mail] (p0lloc)]

Hello,
If I'm not mistaken, this is being tracked in multiple kernel issues, https://bugzilla.kernel.org/show_bug.cgi?id=218003 (latest activity) and https://bugzilla.kernel.org/show_bug.cgi?id=217873. It seems that this could be the same IRQ issue that has been affecting many new laptops. The only success I've had is by applying the kernel parameters "i8042.nopnp i8042.direct i8042.noloop i8042.dumbkbd" which makes the keyboard work but with an extreme input delay. I have also tried building my own kernel with an IRQ patch but sadly to no avail. I have the laptop Lenovo IdeaPad Slim 3 14AMN8 so if you have a different model you might have more luck than me.

[Endre Olah (endreolah68)]

Bad news. Tested Fedora 39 beta, with kernel 6.5.7-300. Keyboard/Touchpad does not work.

[Kyrylo Budnyk (kirry36)]

Endre, please. Stop looking for wonder. We're know that this bug NOT FIXED exactly. Why?
Because we're on bugtracker. And a lot another trackers/people also taking care about this bug. Few messages before you i have reported that 6.5.7 kernel isn't working. Moreover, i have tested 6.6-rc5 and its NOT WORK, because there is no working fix. How can it be fixed when this bug report is exist in Open state? This is not bug of several distributives, this is Linux kernel bug. Best thing we can do - start building kernels with patches to find the right fix or even better cooperate with good kernel developers and try to fix together.

[Endre Olah (endreolah68)]

Kyrylo, these guys are working on patches of the base kernel, so -300 kernel on Fedora might be having some solutions. Actually I can say that on Fedora, even those buttons were not working which was working on Ubuntu. Like the brightness buttons or the airplane mode button. Let me believe in miracles. :D

[Kyrylo Budnyk (kirry36)]

Endre, i don't know what "these guys" are doing, but now we're have temporary fix for it. Tested but can be unstable. Mario, Boris from AMD and Hans from Fedoraproject keep working on it.

[Endre Olah (endreolah68)]

Hi Mario,

thanks for all your and the others efforts, who worked on the solution.

May I ask, how will we know that the fix is implemented in a distribution? Myself using Ubuntu 22.04, onwhich the patch was available and now I can use the keyboard, but I am afraid, if an update is popping up and installs a new kernel, I might loose the keyboard again.

Thanks

     Endre

[Pradip Kumar Das (pradipkumardas)]

Thanks Endre for bring up this question.

I had upgraded to 23.04 few weeks ago, and when I got to know that 23.10, which is considered as development version as of now and comes with kernel 6.5 and now available in the official site, I got the previous version upgraded to this latest yesterday, and found that keyboard and touchpad issue were not addressed in that kernel yet.

Many who are willing to get official update instead of applying patch by themselves, a response on tentative availability of fix through offical distribution will be helful.

Regards,

skipping 5.15, this will be for 6.2 and up (plus oem-6.1)

[Quinten Van Ginderen (quintenvg1)]

@timo,

Just for some clarity, when you say no longer affects; does that mean you can get the kernel from kernel.org, install it and it will work just like that or does it mean when you install a kernel with a tool say mainline, it should work?

Or are we now waiting for the patch to be in the apt/dnf/pacman/zypper repos?
I'm a bit of a noob on the patching cycle.
For now i'm running a patched unsigned kernel 6.1.59. unfortunatly Virtualbox won't run unless the modules are signed however.
I was looking in how to sign it myself but it seems like certificate hassle.

Kind regards.
Quinten.

Happy patching :)

I mean that there's no need to add hwe-* as being affected, because the parent kernel for hwe-6.2 is lunar, and it's already covered here.

And I'm actually reluctant to add these to oem kernels, because they'd need to be tested as well.

The fixes are also available 6.5.10 and 6.5.10 is currently available in Fedora updates-testing.

So you can install Fedora 38 with an USB keyboard + mouse attached to the laptop and then do:

sudo dnf --enablerepo=updates-testing update 'kernel*'

Reboot into the new kernel and then the keyboard and touchpad should work.

Note coming Tuesday Fedora 39 gets released, so you may want to wait till Tuesday and then download and install F39 right away to avoid having to upgrade later.

To download Fedora go to: https://fedoraproject.org/

[Endre Olah (endreolah68)]

Downloaded yesterday the 6.5.10 kernel and compiled it for Ubuntu 22.04 LTS. It works now without any patching needed. So I can confirm that it fixed in this kernel version.

Upgraded to Ubuntu 23.10 yesterday, which installed an earlier kernel, but left he 6.5.10 kernel on the machine too. Forcing to load this kernel automatically made it work under 23.10.

So for me the problem is solved until the official update is including the improved kernel.

This is expected, F39's images use 6.5.6 as kernel and the fixes for this are only available in 6.5.10 and later.

So you need to either install 6.5.10 for your current distribution (most distributions have some mainline kernel repository somewhere) or install Fedora 39 using an usb keyboard + mouse and then install all updates and after that things should work.

[jnemeiksis (jnemeiksis-linux-kernel-bugs)]

yeah, after update kernel everything okay. Thanks!

[Quinten Van Ginderen (quintenvg1)]

I can confirm too, i'm just waiting for the latest kernels to show up in mainline, so i can install them and have them signed. So that virtualbox will finally worrk too.

It's been an honor to test along you people!!

Happy patching. :)

[Endre Olah (endreolah68)]

I have switched to Debian and downloaded the latest kernel from kernel.org. As the current kernel on Debian was 6.1.0-13, I have selected the 6.1.62 kernel source. I have followed the steps and Quinten written earlier, except the patching steps as it is not needed anymore and after installing the compiled kernel, it works perfectly.

[Quinten Van Ginderen (quintenvg1)]

Hey Guys,

I have recently installed the zabbly kernel in debian, it is based on version 6.5.10, no patching is needed the modules are signed, i'd say we're set until ubuntu and ubuntu based dsitro's are on kernel 6.5.10 or newer.

Happy patching, even tho patching for this bug is probably nearly done at this point :)

If the problem still exists, change the tag 'verification-needed-jammy-linux-oem-6.5' to 'verification-failed-jammy-linux-oem-6.5'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Hi,

Does the last messages indicates that the fix will be available in an upcoming update for the OS?

[Danielle Satterfield (dsatterfield)]

Maybe not for your G2 ALC. This ticket was specifically focused on the G4 AMN laptops.

[Timo Aaltonen (tjaalton)]

for the generic distro kernel it'll get fixed via normal stable backports, which at this point means the fix is available to download in February next year, at the earliest

[Nerio Miguel Rincon Rodriguez (n3rio)]

Hi people,

I guess it would be a good idea to let you know that the problem on Lenovo V14 G2 ALC is now fixed, didn't do anything, it just worked after an update.

For all Linux beginners that don't want to compile their own kernel:

It seems that it's already possible to download and install a pre-compiled kernel via GUI:

Simply follow these instructions: https://9to5linux.com/you-can-now-install-linux-kernel-6-5-on-ubuntu-heres-how

You'll need to enter the following commands into your terminal:

sudo add-apt-repository ppa:cappelikan/ppa
sudo apt update && sudo apt full-upgrade
sudo apt install -y mainline

After that is done you will find an application called "Mainline Kernels" in your desktop-environment.
Start that application and install a new Kernel (I installed kernel 6.5.11).

After you installed that kernel, enter this line in your terminal:

sudo apt --fix-broken install

Restart your notebook and enjoy your built-in keyboard and trackpad.

PLEASE NOTE: Like yourself I'm a linux-noob. I can only confirm that this works on my configuration:
Ubuntu 22.04/Gnome 42/Kernel 6.5.11

But in my case it works like a charm.

Good luck!
