Comment 0 for bug 1976556

Used Ubunutu 22.04 with the current 5.15.x Kernel, cross tested with Linux Mint and 5.14.x Kernel.

I have a Lenovo 300e 2nd Gen with an ELAN Touchscreen AND Touchpad with AMD processor.

The Touchscreen is working flawlessly.
The TouchPAD is dead.

According to the Windows driver:
%ELANHIDDeviceDesc% = ETD_HID_PTP_WIN10_Group2_Inst, HID\VEN_ELAN&DEV_0660&Col01 ; ClickPad for Capela 14e Windows
%ELANHIDDeviceDesc% = ETD_HID_PTP_WIN10_Group1_Inst, HID\VEN_ELAN&DEV_0661&Col01 ; ClickPad for Windows 100e/300e
%ELANHIDDeviceDesc% = ETD_HID_PTP_WIN10_Group3_Inst, HID\VEN_ELAN&DEV_066C&Col01 ; ClickPad for 100e/300e AMD Pollock
%ELANHIDDeviceDesc% = ETD_HID_PTP_WIN10_Group1_Inst, HID\VEN_ELAN&DEV_066E&Col01 ; ClickPad for 100W&300W Gen3 AMD Pollock
%ELANHIDDeviceDesc% = ETD_HID_PTP_WIN10_Group1_Inst, HID\VEN_ELAN&DEV_066F&Col01 ; ClickPad for 300W Gen3 Intel JasperLake

....it is an ELAN066C

According to similar solutions i tried to block several built in kernel modules, without success.
