To the previous comment: I'm a long-time user of many Dell laptops, and I can confirm that Dell does NOT disconnect the display when it closes. Whether running Windows, you can clearly see the glow of the monitor still on, when closed, if configured to stay on. (Which is also proof that it is completely possible to close the lid, and neither lock nor turn off, if that's what you want.)
Between work and home, I run 6 physical installations of Xubuntu 18.04.3, 18.04.4, and 16.04.something.
And going back as far as I can remember, to at least 12.04, this has been an ongoing bug.
When I want to use my laptop "docked" (e.g. either physically docked or just all wired up by itself), I have to leave the lid ajar, to prevent it from going to sleep. Really annoying. But, I love me some XFCE so whaddayagonado. I really whish they'd just fix this already. (I've thought about taking it on myself but don't know C or GTK+ well enough, so kind of have to rely on the generosity, expertise, focus, and priorities of other...)
