MinimWatch - no tray icon(s) or desktop launcher

This output doesn't tell you whether it is headless or not. I am fairly sure this is the problem. You should be able to install the full version without uninstalling the headless version as the full version is effectively an add-on to the headless version.

This doesn't explain why you're not getting the desktop launcher icon. I have tried 17.04 with GNOME and the desktop icon is working for me.
