Touchpad not detected

This change was made by a bot.

Would it be possible for you to test the latest upstream kernel? Refer

v4.13 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

kernel-bug-exists-upstream

Please try this kernel:
http://people.canonical.com/~khfeng/lp1708852/

It's fully working now. Thanks a lot!

I've built a DKMS module as a workaround. Install it by

wget https://launchpad.net/~hanipouspilot/+archive/ubuntu/ppa/+files/elantech-0608-dkms_0.1_all.deb
sudo dpkg -i elantech-0608-dkms_0.1_all.deb

The patch should be automatically picked into Ubuntu's kernels because it CCed stable.

I updated module version so it is.

The new package is not released yet.

is there an expected date for the release?

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.

Hi @unameuname,

The packages with the fix for this bug are scheduled to be released to -updates on the week of 09-Oct.

Best.

Could someone who's affected by this issue verify the fix with the Xenial and/or Zesty kernel currently in -proposed pocket?

Thank you.

Hi,
Mine is a Lenovo Ideapad 320-15IKB, and I have the same issue. I tried the method given above, kindly check the attachment for the terminal log for the same.
I did reboot after the installation but the touchpad is still not detected on Ubuntu 17.04 where as it is working perfectly fine on windows 10.

Hi Nase,

as your device might be different, can you run the following command in a terminal (ctrl+alt+t)and paste the result to http://pastebin.ubuntu.com

cat /proc/bus/input/devices

Thanks
