Touchpad doesn't work on Lenovo ideapad-130-15IKB

Question

I recently bought a new Lenovo Ideapad-130-15IKB and installed Ubuntu 18.04 LTS alongside Windows. I encountered some issues as soon as I turned my PC on. The touchpad isn't working at all on Ubuntu but is working fine on my Windows 10. I didn't find the device in my xinput list:

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
    ⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
    ⎜   ↳ YSPRINGTECH USB OPTICAL MOUSE             id=9    [slave  pointer  (2)]
    ⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
        ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
        ↳ Power Button                              id=6    [slave  keyboard (3)]
        ↳ Video Bus                                 id=7    [slave  keyboard (3)]
        ↳ Power Button                              id=8    [slave  keyboard (3)]
        ↳ EasyCamera: EasyCamera                    id=10   [slave  keyboard (3)]
        ↳ Ideapad extra buttons                     id=11   [slave  keyboard (3)]
        ↳ AT Translated Set 2 keyboard              id=12   [slave  keyboard (3)]

I tried to change the kernel version from 4.1k.0-15-generic to 4.18.0-15-generic

but it didn't work unluckily.

From dmesg | grep i2c the output is:

[    0.917926] i2c /dev entries driver
[   27.763102] i2c_hid i2c-ELAN0620:01: i2c-ELAN0620:01 supply vdd not found, using dummy regulator

If there's any solution please post it.

Pilot6 do you have any information about my problem please ! — Said Ougouadfel, Feb 15 '19 at 15:43
First of all touchpad and wireless are two different problems. Please remove one issue from your question, otherwise the question may be closed as too broad. You can ask another question regarding the other problem. Please [edit] your question. — Pilot6, Feb 15 '19 at 15:55
So please add the output of xinput to your question. Format it with {} button. — Pilot6, Feb 15 '19 at 16:19
This touchpad is not supported by the 4.15 kernel, but is supported by the 4.18. See this https://askubuntu.com/questions/1049787/lenovo-ideapad-330-touchpad-not-working I think the easiest solution will be to install Ubuntu 18.10 that has that kernel by default. — Pilot6, Feb 15 '19 at 16:27
You have another model of Elan touchpad, 0620. I'll check if it is supported by any kernel yet. — Pilot6, Feb 15 '19 at 17:26
It is supported by the 4.20 kernel. You can install a mainline one. I can post a detailed instruction a bit later. — Pilot6, Feb 15 '19 at 17:28
Please [edit] your question and put there the output of dmesg | grep i2c. — Pilot6, Feb 15 '19 at 17:29
If there's any solution please give it to me and thanks a lot Pilot6 for your help — Said Ougouadfel, Feb 15 '19 at 17:34

You have a new touchpad model that is not supported by current Ubuntu kernels. The model is ELAN0620.

Luckily support has been added to the 4.19 Linux kernel.

I suggest installing a mainline kernel using UKUU.

Install UKUU this way

sudo apt-add-repository -y ppa:teejee2008/ppa
sudo apt-get update
sudo apt-get install ukuu

Start UKUU using GUI, or by running ukuu-gtk in a terminal.
Choose the latest 4.19 kernel there and press Install.
Reboot.

The touchpad should start working.
