My experience with version 384.90 remains the same, it is usable, as long as:
1. plug the laptop and the screens to the dock before booting the machine
2. do not under any circumstance hibernate or use screen lock
If you get the blinking screen, drop to a shell, say "Crtl+Shift+F3", and reboot the machine or force a X restart with "Ctrl+Alt+Bksp" (if you have activated this shortcut)
As far as I remember, only the laptop is certified, not the combination laptop+dock.
I share your frustration, but this is not a problem of ubuntu on its own, its a problem with the nvidia linux driver
