Hi,
I have a Dell Vostro 15 3000 series laptop. It worked perfectly until today. I have the latest Linux Lite version and have installed updates today.
Immediately after the updates, my touchpad stopped working. I tried various solution I found on Google, none works.

What do you mean excatly by "stopped working"? Doesn't tab work? Neither right nor left button works? it doesn't work at all? I ask because depending on the specific issue you may have there might be a specific solution. For me, it looks like the driver module isn't being loadaed. Did you try rebooting your pc after updating/upgrading? If you didn't, try that and see if it works. Also, what's the output of this command?
grep -e "input driver" /var/log/Xorg.0.log
-
The touchpad does not work at all - neither cursor movement nor buttons.
I tried rebooting several times. Also tried turning the laptop off completely, waiting several seconds, then turning it on again. It didn't help.
Here is the output:

Let's see if it is kernel update related. When you reboot, hold down Shift and then go to Advanced and choose a previous kernel to boot from. Try that each time to see if functionality returns.

Bingo! Going back to the previous kernel solves the issue.

Might pay to Google the kernel version and Ubuntu to get a clearer idea eg. "kernel 4.4.0-131-generic #157-Ubuntu SMP touchpad bug" If no finds, then submit the bug to Ubuntu.
