Verified with Kubuntu 17.10 on a Zbook15 G3 I found a workaround in another bug report of ensuring that "noquiet nosplash" are passed on the kernel cmdline at grub. This works but disables all of the pretty splash screens (perhaps not such a bad thing). There appear to be other variations of this workaround that may be device specific.
There is still something squirrely suggesting a timing or ordering issue. If I stop in grub and just view the current grub entry and boot with ctrl-x, sometimes the screen will go completely black, with no inputs. On a hunch it was waiting for the encryption password, I entered it and waited. Graphics came up somewhat normally although all the graphics terminals except the graphics one were completely black.
