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.
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.
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?
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.
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”
