I am using Lenovo Yoga 260 with OneLink+ Dock and just started to have the same problem with Ubuntu freezing. I am using 18.04.1. Symptoms: (1) If I have it connected when I power up, it will hang and you can only hold down the power down button. (2) If I connect the Dock link after I power up BUT before I login, it will also hang (3) After I login, connect the Dock link, works fine. But noticed if it goes to screen lock, it will hang again but have not tested if this happens every time.
