I'm hesitant about installing X11 on a server machine because I want it to contain the absolute minimal amount of software needed.
However, some GUIs (for FFMPEG encoding, etc) are useful so I was thinking about installing X11.
What is the absolutely minimum number of packages I would need to install in order to run some simple (?) GUIs like the frontends for FFMPEG, etc. I don't think I need a window manager or anything else, etc.
