Hi Po-Hsu,
I spent this evening installing Ubuntu. I tried Xenial, Bionic, Focal and
Groovy.
The proposed release worked on Xenial, but not on any of the others.
Just to confirm the process: I installed a fresh copy of the release,
then went to the developer options tab and ticked the proposed box.
Then updated and then upgraded. Rebooted and then tested for the
trackpad function.
Let me know if I needed to do something different or to try again.
Regards,Tom

Hello Tom,
It will be great if you can help out to verify this.
To do so for Xenial, you will need to install Ubuntu Xenial and enable
the "proposed" pocket [1] on it, then dist-upgrade to the latest kernel
and reboot to see if it works.
The same applies to other releases, you can verify the version that you can.
Thanks!

Bug description:
[Impact]
Touchpad on a ByteSpeed C15B laptop is not working.
User will need to add i8042.noloop=1 to boot options to make it work.
[Fix]
* a48491c65b513e ("Input: i8042 - add ByteSpeed touchpad to noloop table")
This fix can be cherry-picked into all affected releases.
[Test Case]
Test kernel for Bionic / Focal can be found here:
https://people.canonical.com/~phlin/kernel/lp-1906128-C15B/
And they have been tested with positive test results.
[Where problems could occur]
The fix is just a small and simple hardware quirk. I can't think of any
potential problem for now.
== Original Bug Report ==
Touchpad hardware is OK and works for Win10. Not working for live disc, not
for 18.04 and not for 20.04 after upgrading. I've attached a Logitech wireless
mouse with its USB adapter and that works. Bluetooth is also missing, but I
have not started trying to skull that out. I'm happy to help try debugging
things, and to help resolve the issue.
