I am using Ubuntu 18.04 running on lenovo carbon yoga x1 (1st Gen).
Everything work fine most of the time, but after I put the computer to suspend and then wake it up in the am, the mouse goes a little whack:
- the left click of the mouse doesn't work.
- the sliding lock screen for example looks like it's stuck in drag mode, I can slide up and down but not all the way, and I have to power cycle the machine to get to the login box.

Faced this problem today and this is what worked for me.

Make sure your device module is psmouse by running,

lsmod | grep psmouse

if its not, find the relavant module name.

$ cd /lib/systemd/system-sleep/

$ sudo vi fixtouchpad

then paste and save the following

#!/bin/bash

[ "$1" = "post" ] && exec modprobe psmouse

[ "$1" = "pre" ] && exec rmmod psmouse

exit 0

This will reload your psmouse module after resuming. Replace 'psmouse' with your module name.

Be sure to make the script executable

sudo chmod +x fixtouchpad

I was having similar issues with 18.04 and they actually got worse since upgrading to 18.10. I have a Logitech "unifying receiver" that has both a mouse and keyboard paired with it. When resuming from sleep, fairly often either the mouse or the keyboard no longer work. I don't remember suffering these issues with 17.10...

What just fixed it for me was:

for mod in hid_logitech_hidpp hid_logitech_dj usbhid; do

   sudo rmmod $mod && sleep 3

   sudo modprobe $mod

done

(not sure what the various modules are for but they looked like good candidates). I used my laptop's integrated keyboard to type this. If the approach works, I might consider @imeshU's approach to hook this into the System-D sleep/resume process.
