Hello. I have trouble with working touchpad on Lenovo IdeaPad 5 14IIL05.
First i install OS without UEFI - touchpad didn’t work
After i reinstall OS via UEFI - once touchpad work in live session
After complete install OS, touchpad work only on 5.6.6 (stock) kernel. Next i update BIOS and touchpad stopped working on any kernel. Downgrade BIOS on previous version not solved problem.

In Windows 10 this device detected:
VEN_MSF&DEL0004&Col01
UID_093A&PID_2510&REV_0100

As i inderstand this I2C HID device.
dmesg | grep i2c:
[ 1.434574] platform i2c_designware.0: failed to claim resource 0: [mem 0x00000000-0x000001ff]

Also when my laptop wake up after waiting mod. May be show logo disabled/enabled touchpad. But i not have Fn-key for this action.

How enabled this touchpad?

The xinput return:

⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ xwayland-pointer:17 id=6 [slave pointer (2)]
⎜ ↳ xwayland-relative-pointer:17 id=7 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ xwayland-keyboard:17 id=8 [slave keyboard (3)]

Something incomprehensible and similar to a touchpad is

There is no touchpad device as such. But the same results were obtained when it was working.

Tell me please, how downgrade libxinput?

5

Go into dnfdragora and search in the not-installed category for libinput, and download the version 1.15.4. It should then ask you that it will downgrade the current version, and do so.

6

Thank, but i try via terminal:
sudo dnf downgrade libinput

Current version is 1.15.4, but touchpad not work :-(. Load system in previous kernel - nothing.

7

After downgrade libinput i observe, sometimes after wake up from wating mode - system is freezing. I close laptop on couple of seconds then opened and freeze goes away.
Anybody have solution how make the touchpad work?

8

Thank you [vmike] :+1:

Sorry, but i not understand what driver is nedded.
I have libinput, but i not installed synaptics or elan drives becouse i not fully understand what the device i have.
I understand is I2C HID devices. libi2c i installed.

This is a well-lnown bug with the IdeaPad 5 in the Linux kernel. For more information see:
https://bugzilla.kernel.org/show_bug.cgi?id=208171

…and many other discussions.

It is supposed to be fixed in v5.9 of the Linux kernel, apparently.

11

I hope this fixed. In parallel i opened on redhat bugzilla this issue:
https://bugzilla.redhat.com/show_bug.cgi?id=1871793

12

Thanks, but…

You are not authorized to access bug #1871793.

Hmm, why is this a private bug?

13

:joy: Seems it’s my mistake. When i create bug-report in field Public selected fedora_contrib_privat and didn’t pay attention on private.

14

It’s still private, so can’t you make it public again?

15

I’m afraid I don’t have rights to change groups. At the same time, there are 21 people in the mailing list.
I’ll try to request an opening.

16

It took a long time, but the problem was solved.
The solution turned out to be banal-reset the BIOS
or you can:
sudo grubby --update-kernel=ALL --args=“pci=nocrs”

Now bug report opened everyone: 1871793 – Not work touchpad on Lenovo IdeaPad 5 14IIL05
