I am setting up a lightweight VM, following the guide in the Ubuntu Documentation
What I want to be able to do is ssh into the VM and then launch a GUI application. I don't need / want a desktop.
First I installed xorg. But I can't launch a gui. The next step in the documentation is to install a "Window Manager", but it is not clear why this is necessary.
What is the smallest program that will run a gui?
I asked this on ubuntu.SE, but all of the answers required installing a window manager, all of which provide a desktop. The best answer was to go ahead and install a window manager and then limit what startx does with the .xintrc file.
Installing openbox increased the size of my original VM from 0.9 to 2.2GB. I want to minimize the size of my VM. What is the smallest group of programs that will allow me to launch a GUI?
