The touchpad of my X1 stopped working again .
I tried to uninstall the Synaptics device, which makes it work again after the first reboot, but when the Synaptics driver is automatically reinstalled it will stop working again. Strangely gestures like 4 finger swipe works but the cursor doesn't move, and the touchpad driver diagnostics also seems to see finger movements.
It seems that the device is detected as as Synaptics TouchPad V9.16 on PS2 Port instead of using the SMBus:
Can anyone help with this issue or post screenshots from their working X1 C6 (Thinkpad tab in the mouse properties and press Alt+Shift+i) ?

I also had this issue on a brand new X1C6 that I received two days ago. I was able to resolve my issue but I had to do 2 fresh installs before I finally got it fixed, and I can't even explain what process finally fixed it. I just know it's fixed because your symptoms sound like mine and I haven't had the issue in over 24 hours now.
