Seriously boring, I agree. Why thrice? Also on Windows 10 Pro it is far from flawless. When started with the tablet in the dock, the second monitor isn't recognized either. But when taken off and put back or when the power supply to the dock removed and put back, the second monitor *is* recognized and the display switches over. Therefore the three runs as above: started and plugged in, removed (just running as tablet) and put back on the top. It doesn't seem to see anything different. I don't know if this helps, yet another bug: when in the dock, Windows 10 does a reboot. When in the dock, Kubuntu 18.04 doesn't. It shows the grub menu, it accepts keyboard input (through the Logitech receiver in the dock), it momentarily starts up X, and then the mouse cursor remains on the screen, and I can move this cursor around with the Logitech touchpad. It stays in this state however, until I switch it off. I have tried a good number of keys in this state to get it to do something, like showing the 'kubuntu' or the login screen, but it wouldn't. So I guess that starting X, it *does* see something that makes it confused. It doesn't crash, it accepts mouse commands, but just sits there. I do hope this is somewhat clear? It does mean, to start it in kubuntu-mode, I have to take it out of the dock in all cases, and once up, I can put it back. Curious ... !
