I have ThinkPad X1 carbon laptop with Ubuntu 18.04. Touchpad and gestures (Scrolling etc.) work perfectly. But sometimes after wakeup from sleep two-finger scrolling won't work. I have to restart the laptop to make it work again. Is there any workaround to prevent this?

I'm having the same issue. I could manage this using a temporary workaround by removing the touchpad module from the kernel and adding it again. To remove:
sudo modprobe -r psmouse
To add again:
sudo modprobe psmouse
After that scrolling works for me.
