I have seen this using two identical docking station plus monitor combinations. I am still trying to find a pattern. I often find the laptop going to sleep again immediately after being woken up. When it freezes, the screen saver is visible on the internal display and the external monitor is (I think) enabled but blank. I saw this with 4.13.0-13-generic, and have not yet had the chance to test it with 4.13.0-15-generic. I have also not had the chance yet to try to ssh in.
