Ubuntu – Touchpad of Lenovo Ideapad S145-15IIL not detected in 18.04 and 19.10, Ubuntu and Kubuntu

I bought a Lenovo IdeaPad s145-15IIL, which works with Windows 10 with no problems.

I installed Ubuntu, but the pointer of the mouse was stacked in the center of the screen. I can't move it with the touchpad, only with the mouse.

I tried both LTS and 19.10 of Ubuntu and Kubuntu but the problem persists.

Followed an online guide, and found no touchpad was detected in the list of inputs.

How do I enable the support of my touchpad in Linux?

Best Answer

I found out that they are working to add the proper drivers for this touchpad. Anyhow I managed to fix this problem by adding these lines to the kernel parameters:

i8042.nopnp=1 pci=nocrs

Once done, do

sudo update-grub

than restart the system.
