I am setting up a light weight VM, following the guide in the Ubuntu Documentation
What I want to be able to do is launch a GUI application. I don't need / want anything on the desktop.
First I installed xorg. But I can't launch a gui. The next step is to install a "Window Manager". So I installed xfce4, and then
startx launches a desktop.
What do I need to launch a gui but not launch a desktop?
