I have an Elantech touchpad that is not working with Ubuntu 18.04. It doesn't recognize it at all, there's nothing about it in xinput and nothing coming up in cat /proc/bus/input/devices for example.

I've tried some of the solutions suggested for previous versions of Ubuntu, such as editing /etc/default/grub with i8042.nomux=1 and i8042.reset. The patch suggested before won't work on the current kernel as well, so I'm at a loss...anyone have any ideas?

Thanks in advance.

  • Thanks, I looked in the BIOS but only stuff I found was related to low power use...tried toggling it for the touchpad but nothing changed.

Try using these below steps:-

  1. Install the package xserver-xorg-input-libinput
  2. Uninstall xserver-xorg-input-evdev
  3. Uninstall xserver-xorg-input-synaptics
  4. Reboot and see if things work better.

got these steps from 16.04: Elantech touchpad not working on new laptop , and it worked for me

I had this issue and solved it by apt installing the linux-image-generic-hwe-18.04-edge and linux-image-extra-generic-hwe-18.04-edge packages. These are metapackages that contain additional drivers. This will result in installing kernel 5.0.0. It may work with kernel 4.18.0 as well, but I haven't tried that so I can't verify that. If you would rather try that, omit the "-edge" from these package names to install the version 4.18.0 packages. I was also able to get it working using some of the kernel versions on ukuu, but I wouldn't recommend doing it that way as it is unsupported and could introduce other problems.
