The touchpad after sleep/suspend of my ThinkPad X1 will not function correctly.

Expected Behavior:
After sleep/suspend scroll works correctly.

Actual Behavior:
Unable to scroll or correctly click on a window and move it without reloading the driver

Steps to reproduce:
1. Install Bionic on Thinkpad X1 (4.15.0-32-generic)
2. Open something to scroll (e.g. browser, terminal, etc.)
3. Close lid
4. Re-open lid once sleeping/suspended
5. Try to scroll and note that it does not work

Run the following after re-opening the lid
$ sudo modprobe psmouse -r; sudo modprobe psmouse
