Ubuntu – Touchpad not detected on Lenovo Ideapad 320 with Kubuntu 17.04


I just installed Kubuntu 17.04 on a Lenovo Ideapad 320, and the Touchpad is not detected. The touchpad works fine from the Windows 10 installation already on the laptop, but is not detected at all from Kubuntu, so it seems like a driver error.

Here is the xinput output. The Logitech mouse is a USB mouse I am using in the meantime, which works fine.

$ xinput --list

$ cat /proc/bus/input/devices | grep TouchPad

Has no output. I have also tried the psmouse-related stuff suggested here to no avail

It seems like I'm not the only one, this is posted a few other places with no answer, here and here, and maybe here

Best Answer

Install this kernel module. It should fix the issue. Run

wget https://launchpad.net/~hanipouspilot/+archive/ubuntu/ppa/+files/elantech-0608-dkms_0.2_all.deb
sudo dpkg -i elantech-0608-dkms_0.2_all.deb

Then reboot.

You need to disable Secure Boot in BIOS to let the module load.

Another option is to install this kernel.
