Same install as my prior photo on Lubuntu thread, as my Ubuntu install is a multi-desktop install.
Same four monitors turned on (fifth still off & panels mostly configured to only show when mouse pointer is over them, thus MOST panels aren’t visible) with fifth monitor turned off/disabled and not shown… First image shows off wallpapers, pictures of local birds 
Same mixture of quick launch items where I want them, clocks showing UTC & local time matching the setup in Lubuntu/LXQt… though actually Lubuntu/LXQt was made to mimic this setup.
This Xubuntu/Xfce setup is less tailored than it used to be, as I could achieve more in Xfce & took advantage of that for some time, alas I’ve since removed some of those additional tweaks so there is less difference for when I login here with in a Xubuntu session, or in a Lubuntu (LXQt) session, or Ubuntu.Desktop (GNOME) session etc.
The setup will NOT be pretty (hopefully the bird pictures make up for that!), but I find it works for me.
This image shows fastfetch output on a quickly opened terminal… There are trails were I moved it around so it’d fit on my main monitor and not cover the panels so I could have them show (using mouse-pointer position for one) but the trails are seen on the saved screenshot!!?? as outside what the monitors actually show (to left of bottom left monitor, and below my far-left-top-row monitor).
(Please Note: I have the mouse pointer over bottom-left side-panel so it’ll show, and you can see it trying to tell me what I’m hovering over; this is why you see Disks or Clementine being shown the way it is)
I use the same WM for both Lubuntu/LXQt & here on Xubuntu/Xfce, ie. xfwm4 which is why window border will look the same (same pills theme used) as Lubuntu, though lack of open/active windows hides that somewhat.
Birds in images; Pied Currawong, Grey Butcherbird, Australian magpies (& spotted doves) & Little Corella (the old short/face.washer on the clothes line is! washed regularly; but put out so the Corella can take off the pegs so it’ll drop on the ground)
