If you have reinstalled the Operating System in your Slimbook Eclipse and the touchpad does not work, follow the steps mentioned below.

On the other hand, in the Classic and Katana models, a failure in the kernels 4.10.0-40, not present in the kernel 4.10.0-38, has been detected. The problem is that when you suspend the computer (action that happens when you lower the lid) and resume it, the mouse pointer goes to the upper right corner and does not respond again. This is because the kernel does not correctly load the touchpad protocol.

This error has been reported to Ubuntu here, but while they fix it, we bring you a solution, load the forced protocol at the start of the operating system.

1- We will have to edit the grub to add psmouse.proto=exps while loading the kernel. We can use vim, nano, or gedit, for example with the following command:

sudo -H gedit /etc/default/grub

2- Once the file is open, we look for the line (in this tutorial we will omit the rest of the parameters of the line):

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

and we replace it for:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash psmouse.proto=exps"

3- We save the document and close it.

4- Next we will update the grub, executing the following command.

sudo update-grub2

5- Once finished, we will have to restart the computer, and we will have our touchpad working correctly.
