There is no misalignment of expectations here. What am after is to returning my system to a working system (GUI) with out centrifydc. I know that if I install ubuntu then add centrifydc I can join a domain and then install Lubuntu-desktop and it works.
However I stupidly did it in the wrong order and now can not get back my GUI.
P.S.
I am writing this on a ubuntu-server with Lubuntu-desktop and I can log in as an active directory use if I so wish.
