Meanwhile... I compiled a Kernel 5.7.0 for testing on this exact laptop
model with
Device Drivers -> Input device support -> Touchscreens -> Elan eKTH I2C
touchscreen as MODULE.
Touchpad WORKS instantly with the default setup (with xserver-xorg-
input-libinput). No extra driver needed.
=>
FYI: Touchpad still not working in latest mainline kernel
5.7.0-050700-generic and/or installable drivers like xserver-xorg-input-
libinput, xserver-xorg-input-evdev, xserver-xorg-input-mouse. (without
manual configuration). I still believe a wrong kernel driver is active
for this device.

Updated kernel to mainline 5.6.15-050615-generic. Helps with other
issues but touchpad still not responsive. At least error messages in
dmesg are gone.

Same Issue here. Trying to get the touchpad runing on an
Lenovo IdeaPad 5 15ARE05
Same behaviour like "elants_i2c i2c-ELAN0001:00: unknown packet" in Dmesg
Touchpad is active but messages are not interpreted correct.
