[Solved] Lenovo Legion7 touchpad not working

[pogwizd]

Hi,

I have a Lenovo Legion 7 (16IRX9), and I cannot get the touchpad to work at all.
I am quite sure it should, as when starting from the Gentoo live CD, it is working.

Here is the output of my lsusb:

Code: Select all

I trie all the PINCTRL & LPSS after reading the following thread: https://forums.gentoo.org/viewtopic-t-1 ... chpad.html

So I was wandering if someone might have an idea why this is not working?
Thanks in advance for the help.

I have a Lenovo Legion 7 (16IRX9), and I cannot get the touchpad to work at all.
I am quite sure it should, as when starting from the Gentoo live CD, it is working.

Please do again boot with the GentooLiveCD and do a "lsmod" + "lspci -nnk". Give us the output of both + your current .config (complete; please see the note about "wgetpaste" in https://wiki.gentoo.org/wiki/User:Pieti ... nformation ). I am sure we will find the missing option.

[pogwizd]

Sure thing pietinger,

Here is the lsmod from the liveCD: https://bpa.st/raw/A6WA
Here is the lspci -nnk from the liveCD: https://bpa.st/raw/L7CQ
Here is my kernel's .config:https://paste.gentoo.zip/8lZbW5da

[mirekm]

I had similar problem with my laptop. It have touchpad on i2c bus.
Try several livecds, to see on which it works. Then you cas findout which modules handle it.

[pogwizd]

That's the first thing I tried, but its been over a month now, and cannot find the missing component in my config

[logrusx]

There are several kernel config options for ELAN, I don't see them in the presented config sample.

Open menuconfig, press / and type elan. Look for them.

Also what procedure you follow to build your kernel?

Are you using and initramfs? If yes, how did you built it?

With genkernel I was never able to produce an initramfs that setup my touchpad correctly. I noticed gentoo-kernel used dracut and switched to dracut which was able to do it. Then I entirely dropped the initramfs.

Have you tried gentoo-kernel-bin?

Also lsusb and lspci are almost useless here. You need hwinfo or dmidecode, I don't remember which anymore. You can try to dig up my post about how I configured my laptop. A bit different, but might still give you some clues. It's Legion 5 pro 16ACH6H.

EDIT: here it is: https://forums.gentoo.org/viewtopic-t-1145154.html

My guess is that it's just because the MEI_ME driver is missing, but I still recommend enabling the others as well. That's all you need for your touchpad (so you can disable all other PINCTRL modules and more):

Code: Select all

CONFIG_X86_INTEL_LPSS=y
CONFIG_INTEL_MEI=y
# CONFIG_INTEL_MEI_ME is not set
CONFIG_INTEL_MEI_TXE=y
CONFIG_I2C_I801=y
CONFIG_PINCTRL_ALDERLAKE=y
CONFIG_MFD_INTEL_LPSS_ACPI=y
CONFIG_MFD_INTEL_LPSS_PCI=y
CONFIG_HID_MULTITOUCH=y
CONFIG_I2C_HID=y
CONFIG_I2C_HID_ACPI=y
CONFIG_USB_HID=y
CONFIG_HID_PID=y
# CONFIG_USB_HIDDEV is not set
# CONFIG_INTEL_IOMMU_SVM is not set
# CONFIG_INTEL_IOMMU_DEFAULT_ON is not set
# CONFIG_IRQ_REMAP is not set

(CONFIG_USB_HIDDEV should not be needed ... but to be on a safe side IOMMU is important)

To my knowledge, the other IntelManagementEngine (MEI) modules are only required for video, but I trust Intel to do anything; if in doubt, activate them as well (from your "lsmod"-list):

mei_hdcp
mei_pxp
mei_me
mei

The output of your "lsmod" tells me your touchpad use the HID_MULTITOUCH ... if this does not work (because it is an ELAN or you use a Synopsys DesignWare PCIe controller) I would need the output of "dmesg" after booting our LiveCD. In the mean time you could look to this:
https://wiki.gentoo.org/wiki/User:Pieti ... C_Touchpad (and the next chapter).

[pogwizd]

Sorry it took some times to answer, but you know, to try everything the kernel wanted to be recompiled entirely every time, and last a bit.

So I trie to add the ELAN components as suggested logrusx, but it is not it unfortunetely. Those are the one I tried:

OF
HID_ELAN
I2C_HID_OF_ELAN
MOUSE_ELAN_I2C
MOUSE_ELAN_I2C_SMBUS

Also, to answer you question, I build my kernel with the following command:

Code: Select all

make && make modules_install && make install

As for the initramfs, I have it, and prepare it with dracut.

As per pietinger's suggestion, I try back the mei modules. I say back, because in fact I put them at the beginning, and removed them since they produce error at boot, and does not load.
So I tried all the ones you wrote, just to be in the safe side, but nevertheless, here is what I've got:

Code: Select all

But when I woke-up this morning, I noticed I've missed the following three:

Code: Select all

CONFIG_INTEL_MEI_GSC=y
CONFIG_INTEL_MEI_VSC_HW=y
CONFIG_INTEL_MEI_VSC=y

I will try them out, and edit my answer accordingly

EDIT:
So, with the three additional options mentioned this morning, still nothing. And the mei_me loading error messages are the same

Also, here are the additional information mentioned by logrusx:

• For the dmidecode: https://bpa.st/raw/3XEA
• For the hwinfo: https://paste.gentoo.zip/i6b51Q9E

[logrusx]

So, with the three additional options mentioned this morning, still nothing.

Can you build those in the kernel?

Also, here are the additional information mentioned by logrusx:

• For the dmidecode: https://bpa.st/raw/3XEA
• For the hwinfo: https://paste.gentoo.zip/i6b51Q9E

With working kernel or not? If it's not, then they are useless. It looks like it's with the non-working kernel. Did you try gentoo-kernel-bin?

[pogwizd]

Can you build those in the kernel?

Those were build in the kernel when I tried them (not as module)

With working kernel or not?

Yes

[logrusx]

This is my config: https://0x0.st/KXw3.txt

It is for AMD and Designware but I believe the touchpads are connected in similar way for both laptops and this is where the problem is. I hope it helps somehow. I'm out of ideas.

Best Regards,
Georgi

[pietinger]

pogwizd,

if a MEI module gives you errors then something is very wrong with your kernel/kernel-.config. Have you ever edited the .config with an editor? I so, please read this: https://wiki.gentoo.org/wiki/User:Pieti ... it_.config

(best is to read the complete wiki article )

Unfortunately, I will be offline for the next two days. In the meantime, please do the following:

1. Boot our LivCD and then do number 2 of:
https://wiki.gentoo.org/wiki/User:Pieti ... _you_start
2. Do also a "dmesg > dmesg.txt" (because it could be we need it in two days)

Take your time for doing this now:

1. Get the latest gentoo-sources-6.16.5
2. Take your "lsmod"-list and ...
3. Configure a completely new kernel with "make menuconfig" (= DO NO "make oldconfig"); make sure you only enable the drivers you really need (e.g., some PINCTRL drivers are problematic; you only need the AlderLake-Pinctrl because you have a RaptorLake-S machine (i7 14th gen.); yes, they are upward compatible; yes, you see it also in the "lsmod"-list after booting our LiveCD).
4. Start right here and do everything in this article:
https://wiki.gentoo.org/wiki/User:Pieti ... ent_Kernel
5. Activate all MEI modules
6. DONT enable the XE module (you dont need it) for the GPU of your IntelCPU (yes, I know that our LiveCD loads this module)
7. (Dont forget to create your initramfs if you really need it; do you have an encrypted root partition?)
8. Install this kernel as you always do (->bootmanager or UEFI) and boot it
9. Do again a "dmesg > mydmesg.txt"
10. Test your touchpad and update this thread

[mirekm]

I had to add desgnware i2c controller driver to get the touchpad working, although I have intel 14 series cpu.
Before that, I had everything else installed, and it was not able to communicate.

P.S.

pogwizd,

check in your "dmesg.txt" if you have a designware controller (you dont see it in "lsmod" because it is compiled statically <*> in our GentooLive-kernel and not as <M>odule). If so, you will find in my wiki article what to do.

[pogwizd]

pietinger,
I though so that the error shown for the mei were quite problematic. That is why I tried to include them as module within the kernel instead of statically, and in that case there indeed is no error:

Code: Select all

dmesg | grep -i mei && lsmod
[    3.905567] mei_me 0000:00:16.0: enabling device (0000 -> 0002)

And no, of course I did not edit the .config file manually. I know I am crazy, but not that crazy

mirekm,
Yes, you were right. when I started the LiveCD and check out for the designware, I have it:

Code: Select all

dmesg | grep -i desi
[    3.588350] input: FTCS0038:00 2808:0105 Mouse as /devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-0/i2c-FTCS0038:00/0018:2808:0105.0003/input/input7

So now I will try to add it.

PS:

If so, you will find in my wiki article what to do.

I think you forgot to mention the article, or were you thinking about the one for the manual kernel configuration?

PPS: I will not have a lot of time during the weekend, so I may take a bit of more time to answer.

[pogwizd]

So I tried to add (all except the one for AMD) the I2C designware positions in my kernel (tried both staticaly and as module), and nevertheless, it does not start.
This is the only thing that pops-up:

Code: Select all

dmesg | grep -i desig
[    9.035353] [<00000000ebd996f2>] i2c_dw_isr [i2c_designware_core]

I've already emerged the latest kernel, and will try this weekend to do the new configuration as suggested by pietinger.

For info, here are all the information:

• Full dmesg when booting from the Gentoo LiveCD: https://bpa.st/raw/C2FA
• dmesg (grep -i firmware) when booting from the Gentoo LiveCD: https://bpa.st/raw/7JPQ
• dmesg (grep -i stepping) when booting from the Gentoo LiveCD: https://bpa.st/raw/3JQQ
• lsmod when booting from the Gentoo LiveCD: https://bpa.st/raw/IKTQ
• lspci when booting from the Gentoo LiveCD: https://bpa.st/raw/7CFA

[logrusx]

In confused. You said you had to add designware controller to get the TouchPad working and now you say it's not working?

[pogwizd]

logrusx,

What I tried to say is that:

• When I booted the LiveCD, the touchpad works, and I could see that it uses the designware drivers
• Back on my installation, I added those designware position to my kernel, but the touchpad is still not working.

[logrusx]

Have you tried gentoo-kernel-bin yet?

[pogwizd]

Yes, I did. The following: 6.16.5-gentoo-dist
And with it, it works.

I will try this weendend to get the newest kernel from scratch as suggested pietinger

[logrusx]

Yes, I did. The following: 6.16.5-gentoo-dist
And with it, it works.

The procedure I followed was to strip gentoo-kernel's configuration down to what I have now and use that for my custom kernel. There's a lot of stuff you're sure you won't use, don't touch anything in the input,hid, i2c drivers. After you get it working and spirited of the rest of the unnecessary configuration, then you can start stripping those sections.

Best Regards,
Georgi

Hi,

So today is a happy Monday, since I managed to get it work

I created a new kernel configuration from scratch as suggested by pietinger, and added the designeware controller mentioned by mirekm.
Now, I just got to check out why I have those error mess. (Yeah, I still have those about the mei_me, and the message about the ACPI BIOS), but that for other threads

So again, a very big thank you to you all.

PS: and the good purk is that I do not have the initramfs anymore

[pietinger]

So today is a happy Monday, since I managed to get it work

I'm happy to hear that!

Now, I just got to check out why I have those error mess. (Yeah, I still have those about the mei_me, and the message about the ACPI BIOS), but that for other threads

If your sound worked before without the MEI_ME then you could test if your touchpad will work also without it ... maybe ... just test it.
The ACPI error messages I have seen also when/with booting our LiveCD ... maybe here will help only a BIOS update (or you live with it).

So again, a very big thank you to you all.

You are very Welcome!

PS: and the good purk is that I do not have the initramfs anymore

YESS ... ... maybe your system will now start a little bit faster also. Next step is hardening the kernel ...
