I have an Acer Predator Helios 300. The touchpad works in Ubuntu under the "Basic" Mode in the BIOS Settings. But on changing it to "Advanced", it does not work.

I have tried installing i2c-tools,
I have followed the directions in:
Touchpad and typing
Touchpad not working on Ubuntu 14.04
Touchpad under 16.04 not working, which contains directions given under many such questions.

In dconf-editor, there is no touchpad in: org/gnome/desktop/peripherials/

  • Yes, I have mentioned in my question. But I need it to work under "Advanced" Mode because I also use Windows with it, and the touchpad works very poorly then – Aditya Nov 08 '18 at 13:31

The following solution worked for me on my Acer Predator Helios 300 running Ubuntu 18.04 (5.0.0-36-generic) when all else did not-

Check if the solution works
Try running the following command after waking up from suspend when your trackpad is not working- /sbin/rmmod i2c_hid && /sbin/modprobe i2c_hid.
If this makes your trackpad work, follow the below steps to create an automatic solution that runs this everytime you wake up from suspend.

Permanent Solution
1. Create /lib/systemd/system-sleep/touchpad
2. Open the above file and edit it, sudo vi /lib/systemd/system-sleep/touchpad
3. Save the following content in the file- 

#!/bin/sh

case $1 in
  post)
    /sbin/rmmod i2c_hid && /sbin/modprobe i2c_hid 
  ;;
esac
  1. Make it executable- chmod +x /lib/systemd/system-sleep/touchpad

This basically restarts the i2c_hid device upon waking up from suspend.
