Hi Kai,

Hello Kai,
I compiled your test kernel and there was a warning while installing it
that could be referred to the problem we are living. I am copying the
output lines of:

Hello Kain-Heng
I only added the following line on /etc/modprobe.d/blacklist.conf
# Do not load elan_i2c module
blacklist elan_i2c
i2c-hid and hid-multitouch do not appear on blacklist.conf
I attached lsmod.log as requested.
Thanks for your help. I really appreciate it

Ok Kai,
I modified grub options to select the kernel version. Now "uname -r"
output is: 5.4.0-34-generic
Touchpad is still not working. I run dmesg and udevadm again and attached the
logs on this message.
Sorry for the inconvenience.

Hi kai,
I am probably doing something wrong installing test kernel published in
https://people.canonical.com/~khfeng/lp1853277/
I downloaded every file in the link you shared and install them using:
sudo dpkg -i each-.deb-file
However you are right, output of uname -r is: 5.6.15-050615-generic
Hi Kai,
Sorry, I didn't follow you before. I attached both logs again after
