Touchpad not working on Ubuntu 18.04

Try the below command. If it does not show your touchpad then Ubuntu does not support it.
```
less /proc/bus/input/devices
```
After that or if you have already done step 3 you can try
```
sudo rmmod i2c_hid
sudo modprobe i2c_hid
```
If it is showing your touchpad you have to edit the configuration file for GRUB.
```
sudo nano /etc/default/grub
```
and replace
```
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
```
with
```
GRUB_CMDLINE_LINUX_DEFAULT="i8042.reset quiet splash"
```
save the file and exit, then run
```
 sudo update-grub
```
and restart your laptop.

Installing below package will resolve the touchpad issues on Ubuntu 18.04.

sudo apt install xserver-xorg-input-synaptics

On my laptop also touchpad was not working after installing ubuntu 18.04. After installing this package issue got resolved.

shot in the dark... i literally JUST pulled updates and it started working for me!

it's not 100% functionality and sometimes it turns off for some reason but it works!
