First, sorry for my English.

I have a Acer-E5 574G laptop installed Elementary OS 0.4 Loki. Sometime my touch pad will suddenly stopped working and I have to reboot my laptop to get it works again.

The touch pad is fine on Windows 10.

My laptop specs: CPU: Intel i7 6500U RAM: 8GB DDR3L

Touch pad driver: Libinput

Elementary OS version: 0.4 Loki stable (up-to-date), using proprietary drivers for all components

Edit /etc/default/grub, and change the line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet nosplash"

To:

GRUB_CMDLINE_LINUX_DEFAULT="i8042.nomux i8042.reset quiet nosplash"

Then from terminal execute:

sudo update-grub

It should fix touchpad problems :-)

  • Thank you. I will try it for a few days and report back. :D – CNORM Nov 17 '16 at 6:09

One other option would be: Try to disabled libinput (as it has a lot of people have repeatedly report problems with the version that is shipped with Ubuntu and eOS) and fallback to synaptic driver: Trackpad randomly freezes

The proper way to do it is:

sudo apt-get install xserver-xorg-input-synaptics

sudo mkdir /etc/X11/xorg.conf.d
sudo cp /usr/share/X11/xorg.conf.d/50-synaptics.conf /etc/X11/xorg.conf.d
