SOLVED: Elantech Touchpad ELAN061D not working

[pheasant]

Greetings.

We have two Lenovo ideapad-330-15ikb laptops. Though they are the same models, one has a synaptic touchpad and the other what I think is an Elantech. The Elantech does not work with any Linux distro. At the moment I am dual booting Windows 10, Xubuntu, and Mint Xfce. The touchpad works with Windows. I am a newbie to Linux and at a loss having spent the weekend installing various distros. I have been researching and see that others have similar issues. I have tried the numerous suggestions to modifying the GRUB line "GRUB_CMDLINE_LINUX_DEFAULT=" which have not worked.

May I have some help please?

Thank You

I think this module I made will work for you on the 4.15.0-20 kernel, in terminal do

Code: Select all

cd /lib/modules/4.15.0-20-generic/kernel/drivers/input/mouse
sudo wget https://www.dropbox.com/s/e0qhczllt8havfg/elan_i2c.ko

Reboot

[pheasant]

Thank You JeremyB.

I downloaded your module and found, I presume, there was an existing module .ko and the new one renamed .ko.1. I'm guessing the original was not working. I renamed the .ko to .ko.orig and yours to .ko. Loaded module manually, it worked. Ran depmod -a and all works on reboot.

Hope I did this right.

How do I mark as solved?

Thank you again so much. I learned a little.

[JeremyB]

You just need to click the edit button on your original post and add Solved to the subject. If you plan on updating kernels, I think I can make up some source code that will update with the kernel using dkms as that module will only work on your current kernel version

[pheasant]

That would be great, though I don't know when the need might arise. It's not my laptop, but I encourage the owner to keep it up to date. When it breaks then I get involved.

All the best.

[pheasant]

The need has arrived today. With an update the Elantech Touchpad quit working. I am stuck again. Can someone help us? Thank You.

[JeremyB]

In terminal

Code: Select all

wget https://www.dropbox.com/s/tq0kyr7epns6ao6/mouse.tar.gz
tar -zxvf mouse.tar.gz
cd mouse
sudo apt-get install build-essential
cp /usr/src/linux-headers-$(uname -r)/.config .
cp /usr/src/linux-headers-$(uname -r)/Module.symvers .
make -C /lib/modules/$(uname -r)/build M=$(pwd) modules
cd /lib/modules/$(uname -r)/kernel/drivers/input/mouse
sudo mv elan_i2c.ko elan_i2c.bak
cd ~/mouse
sudo cp elan_i2c.ko /lib/modules/$(uname -r)/kernel/drivers/input/mouse/
sudo depmod -a
make -C /lib/modules/$(uname -r)/build M=$(pwd) clean

Reboot

After any 4.15 kernel updates do

Code: Select all

cd mouse
cp /usr/src/linux-headers-$(uname -r)/.config .
cp /usr/src/linux-headers-$(uname -r)/Module.symvers .
make -C /lib/modules/$(uname -r)/build M=$(pwd) modules
cd /lib/modules/$(uname -r)/kernel/drivers/input/mouse
sudo mv elan_i2c.ko elan_i2c.bak
cd ~/mouse
sudo cp elan_i2c.ko /lib/modules/$(uname -r)/kernel/drivers/input/mouse/
sudo depmod -a
make -C /lib/modules/$(uname -r)/build M=$(pwd) clean

[pheasant]

Thank You JeremyB ...

When I run make clean it returns:

make: *** No rule to make target 'clean'. Stop.

[JeremyB]

Do

Code: Select all

make -C /lib/modules/$(uname -r)/build M=$(pwd) clean

I will fix the other post

[pheasant]

Still no joy. Trying to load module returns:

hdk@hdk-330:/lib/modules/4.15.0-38-generic/kernel/drivers/input/mouse$ sudo insmod elan_i2c.ko

insmod: ERROR: could not insert module elan_i2c.ko: Required key not available

Go into BIOS settings and disable Secure Boot

[pheasant]

In BIOS changed "Boot Mode" from "UEFI" to "Legacy Support." System then booted into Windows with no GRUB.

Revisited BIOS and changed above back to "UEFI." Noticed "EFI" order was "Windows Boot Manager" first. Changed order to "ubuntu" and all is well.

Thank You JeremyB

[JeremyB]

You can check

Code: Select all

mokutil --sb-state

To check Secure Boot status, since my old fix worked, I figured Secure Boot was disabled as the kernel has been enforcing secure boot rules for a couple years

[pheasant]

Oops. Revisited BIOS settings again and see I was under "Boot" and not "Security" menu. "Secureboot" is and was indeed disabled all along.

Thank You again and in appreciation for the help I just ordered Linux All-In-One for Dummies (5th Edition) - Paperback (1118844351) from OSDisc.com.

Looking forward to the book!

[JeremyB]

Just added a needed command to posting.php?mode=reply&f=49&t=275517#pr1551538
As sudo depmod -a is needed so the module will be loaded automatically

[phydroxide]

Any solution that doesn't require downloads from (very helpful) strangers' dropboxes?

[JeremyB]

I think it was included in newer kernels
