Lenovo Thinkbook 15-IIL and 14-IIL touchpad not found

[Almir Mulalic]

Greetings,
tried 3 different distros nothing seemd to work, also tried at lest 5 boot parameters and some other hacks that worked on 14-IML for example but nothing worked.

Only driver that's missing is touchpad and it's not even showing in the list.

Current distro: Ubuntu, tried on manjaro and kali

Kernel version: 5.7.1-050701-generic

Xinput log:

Also cat /proc/bus/input/devices shows everything except touchpad.

If you need any more info please let me know, I bought this laptop for linux only and it's really annoying when you cant use touchpad.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1885118

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[You-Sheng Yang (vicamo)]

Please file a separate bug for fingerprint scanner. It's most likely managed by an userspace daemon fprintd and is in a different package.

[You-Sheng Yang (vicamo)]

And please install Ubuntu linux-generic to have generic kernel running while invoking apport-collect. Or, many important information are missing and there's no way to even determine what hardware you have.

[Almir Mulalic (t-h-oor)]

Also, if this seems to be relevant, every time when I wake my laptop from sleep or when I turn it back on , the trackpad icon appears to notify me that the trackpad is activated ( the same one that gets triggered when you click F6) Even if i dont touch the keyboard thats the first thing I see.

Output of journal is attached below.

[You-Sheng Yang (vicamo)]

That's not booted with aforementioned parameters.

[Almir Mulalic (t-h-oor)]

Ur right I forgot to update grub, so sry. Here is the updated version.

[You-Sheng Yang (vicamo)]

Still can't find you touchpad hardware. Please attach your acpi dump info:

  $ sudo apt install acpica-tools
  $ sudo acpidump -o acpi.dump

And attach that `acpi.dump` file.

[You-Sheng Yang (vicamo)]

And, without parameters in comment #41. Thank you.

[Almir Mulalic (t-h-oor)]

Here it is, thanks for your time and fast replys.

[You-Sheng Yang (vicamo)]

DSDT extracted.

[Vladimir (juncer666)]

I also have a problem with my trackpad.
I put various BIOS updates and tried to fix this bug according to descriptions from similar reports in your backlog - no success. Can you guide me on a solution? Maybe I missed something. Thank!
Ubuntu 20.04. ThinkBook 14-IIL.

JUst few days ago one legend resolved it for us.
Here is the link of thread: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1861610
Here is single comment to make it work(from same thread): https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1861610/comments/66

I managed to fix mine on 15-IIL so if you have any questions feel free to ask.
Enjoy

@Almir Mulanic, I'm having the same problem with the same computer (15-IIL), I've followed the comment you've mentioned and I'm running into a kernel panic.

Seems like it can't find the archive file "acpi_fixed.cpio" , even though it's inside /boot as it was mentioned in the comment.
I have to edit grub entry and remove the /acpi_fixed.cpio in the beginning of the boot and than the computer comes up again (yet without touchpad).

The "Be happy" line at the end of that comment didn't work for me :(

What am I missing?
Thankyou!

Alright, if The comment @Almir mentioned does not work for you, take a look at this one:

[ANOMM (anomm)]

Appending "i8042.nopnp=1 pci=nocrs" to boot parameters worked for the touchpad issue on the Lenovo V14-IIL .

Following are the steps I've followed:
1.) Open the file /etc/default/grub for editing, for example by running
      sudoedit /etc/default/grub
2.) Add to the line beginning GRUB_CMDLINE_LINUX_DEFAULT: "i8042.nopnp=1 pci=nocrs" so that it reads:
      GRUB_CMDLINE_LINUX_DEFAULT="i8042.nopnp=1 pci=nocrs"
     ** If other parameters are there between the double quotes, it may be OK to leave them.
3.) Save the file and exit
4.) Run this command to update the GRUB configuration:
      sudo update-grub
5.) Reboot
