When I installed Parallels Tools after the update to Parallels 15 my Ubuntu installations were messed up.
Specifically for the standard Ubuntu 18.04 the autologin didn't work any more and for Xubuntu, which I have configured to start in text mode, startx just hangs instead of starting X. In both cases I installed Parallels tools via the yellow exclam button in X.
