Touchpad not detected on ByteSpeed C15B laptop

This change was made by a bot.

I've tried adding kernel boot switches: i8042.reset i8042.nomux i8042.nopnp i8042noloop

and also noapic. They made no difference.

Found something for same motherboard but different OEM:

Following that bug report (93791), I tried adding i8042.noloop=1 to boo options and that *DOES* fix the problem. Perhaps this laptop needs same patch as the other pegatron?

Thanks!

Hello Tom,
your finding looks promising, I have built two kernels base on that: Bionic 4.15 and Focal 5.4
Could you give them a test to see if this can solve your problem? (Don't forget to remove the i8042.noloop=1 option.)

Thanks!

Hi Po-Hsu,

I installed the Focal kernel (using dpkg -i) then removed the i8042.noloop=1 boot option and rebooted. The touchpad still works, and I confirmed that I was actually running the 5.0.4-57 kernel you provided. Looks really good for Focal.

Would you like me to do the same for the Bionic kernel, or was that just a choice in case I needed it?

Thanks and Very Best Regards!
Tom

Hi Tom,

Thanks for the test, it will be a plus to verify this on Bionic as well.

I will submit this patch upstream and bring it back to ubuntu kernels.
Cheers

Hi Po-Hsu,
I installed the Bionic kernel and booted it. Yes, it is also fixed. 4.15.0-127 works.
Thanks again for your help and Best Regards,
Tom

Patch applied upstream:
https://github.com/torvalds/linux/commit/a48491c65b513e5cdc3e7a886a4db915f848a5f5

And submitted for ubuntu kernels:
https://lists.ubuntu.com/archives/kernel-team/2020-December/115501.html

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Hi - I'm happy to help test if desired. If it's the right thing, I can install and test kernels using these instructions: https://askubuntu.com/questions/700214/how-do-i-install-an-old-kernel

However, I need a clue to exactly which kernels I should test. from https://kernel.ubuntu.com/%7Ekernel-ppa/mainline/ ??

Thanks, 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!

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 in the Software and Updates app and ticked the proposed box. When this was done, the app updated the cache. Then I used Software updater to upgrade and it worked (or not). For the releases that didn't work I also tried using apt from the terminal. Updated and then upgraded. Rebooted and then tested for the trackpad function. Only worked in Xenial.

Let me know if I needed to do something different or to try again.

Regards,
Tom

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.

Hello Tom,

Yes you're doing it right, just reboot after upgrading your system it should be working.

I will mark it as verification-done-xenial based on your test result.
The kernel in the proposed pocket for Bionic is 4.15.0-133.137, can you double check with command "uname -a" in a terminal?

For F/G, they're not ready yet, you will see a comment from "Ubuntu Kernel Bot" on this bug along with a verification-needed-XXXX tag when they have reached in the proposed pocket.

Thanks for your time!

Hi Po-Hsu,
Maybe I'm installing the wrong Bionic? I've installed ubuntu-18.04.5-desktop-amd64.iso. That gives me kernel 5.4.0-62 before proposed, and 5.4.0-64 after enabling proposed.
Thanks,
Tom

Ohh,
right, you will need 18.04.1, which comes with the 4.15 kernel.
http://old-releases.ubuntu.com/releases/18.04.1/
Thanks!

Hi Po-Hsu,
That one worked. Freshly installed, I had 4.15.0-29 and after enabling proposed and upgrading I was left with 4.15.0-135 That kernel worked just fine.
How long until I can expect to see the proposed kernels for Focal/Groovy?
Thanks and Regards,
Tom

Hi Tom,
that's awesome.
For F/G I am not sure about the release schedule. But this commit has already landed on these two kernels. Should be ready soon.

Thank you.

Hi, I loaded groovy, enabled proposed, and the new kernel works just fine. There were other problems with this install. I let the installer update while installing, and that failed bad. I had to tell grub to boot the previous kernel. I let the reporting app send those details.

But, after rebooting with 5.8.0-25 and then upgrading, I got a working system with 5.8.0-42.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results.

If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

Hi Po-Hsu,

Just reiterating that Groovy checked out fine. I did not see a proposed kernel for Focal, even through the Bot said to try it. I get kernel 5.8.0-43 both before and after enabling proposed. Am I missing something again, like with Bionic? It seems that regardless of the 20.04.* I install I always end up with the 5.8.0-43 kernel.

Thanks,
Tom

Hi Po-Hsu,

Happy New Year. I guess I was just too eager. Today I saw an update to a proposed kernel in focal. That kernel was 5.8.0-44 and it works just fine. So you can mark all of these as good to go.

Regards,
Tom

Updated Focal and Groovy verification testing to done. Thank you Tom for testing! :)

Thank you Tom for all your hard work! Much appreciated.
