I have not tested ubuntu-desktop version as yet as i have said ubuntu-server non gui + centrifydc added works. Lubuntu-desktop on top also works.
I don't want to forget about Lubuntu because it is the distro I choose because it is light weight. I hate (dislike) Unity desktop.
As I keep saying I wish to recover another system and return to a working Lubuntu desktop once centrifydc is removed. At present the boot process does not get to the lightdm screen to log in.
Gaining GUI access to that machine is a MAJOR requirement. The system in question is an HP G61 system running Ubuntu-server 14.04.
I am googling and trying things to get the lubuntu-desktop to be restored so the the lightdm login screen with appear again centrifydc has been removed
