I just upgraded to Ubuntu 18.04 and I do not like the Gnome desktop environment. I know that to switch back to unity you have to install ubuntu-unity-desktop and select "Unity (default)" at login, but it doesn't work.
What happens is that I still end up in Gnome, even though I selected Unity. However, this problem seems confined to the root user (which is the user I normally use), since I can successfully log in to other accounts in Unity. How do I fix that? In which log file should I look to find the problem?
(I have been using root to log in to Unity for years now so don't try to talk me out of it).
