Description Alex Alex 2020-09-01 20:01:31 UTC
I recently purchased a lenovo IdeaPad 3 81WE pc and I report that unfortunately using the last available TW snapshot the touchpad is not recognized. 

I tried the solution proposed by Matt Warmerdam (https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe/+bug/1880172) which consists in adding the following to grub: "i8042.nopnp=1 pci=nocrs" and it seems to work. 

I also report this link: https://www.kernel.org/doc/html/v4.14/admin-guide/kernel-parameters.html, where it is indicated that if you need to use "nocrs" you must report the bug.

Information on my pc can be found: https://paste.opensuse.org/31182987

I insert new link with information about the laptop (lspci -vv) without expiry date: https://paste.opensuse.org/8826153
Comment 2 Takashi Iwai 2020-09-23 17:12:55 UTC
Could you give the output of hwinfo?  Rather upload to this Bugzilla please.

I'm sorry I was late in replying, but it's not a good time. I hope that what is provided is sufficient.
thank you for your attention
Comment 6 Takashi Iwai 2020-10-29 06:31:43 UTC
Thanks.  Could you try only with i8042.nopnp=1 option?
If this suffices, we can add the quirk for the specific device in the input driver code.
Comment 7 Takashi Iwai 2020-10-29 06:46:06 UTC
And, if i8042.nopnp=1 works, please upload the kernel messages (output of dmesg) on both working and non-working cases (with and without the boot option), too.

Hi Takashi Iwai,

with option don't work. 

thank you for your attention
Comment 11 Takashi Iwai 2020-11-03 17:03:23 UTC
Hrm.  If you pass both i8042.nopnp=1 and pci=nocrs, does it work reliably?

If it works, could you give the hwinfo and the dmesg output from the working state?

Comment 14 Miroslav Beneš 2022-01-14 14:31:46 UTC
Alex, I apologize for the late response. Has anything changed since back then? There is a much newer kernel in TW now?
Comment 15 Alex Alex 2022-01-14 22:02:55 UTC
Miroslav Beneš, I thank you for your reply, but that pc is no longer in my possession.
Comment 16 Miroslav Beneš 2022-01-17 08:48:25 UTC
Ok, thanks for the feedback and let me close then.
