You do want just 1 "screen" to drag windows between them. IIRC if one has a single display and multiple screens, whether and how one can drag between them depends on the desktop running on top of the server. My recollection is that in ancient days, one could, at least with some desktops, move windows between screens. In ancient days, it was ordinary for me to build the server with imake. In ancient days, the desktops were called window managers. In ancient days, IIRC, there were no multi-monitor screens, so dragging between monitors required dragging between screens. A given "screen" is a big rectangle, and each monitor shows a rectangle of that larger space.

Anyway, to the OP's problem: The weird thing is, it seems like the desktop THINKS my screen looks like this: + + + + + + The "display" looks like this. Portions of it are shown on each monitor. So what happens is, when I do something like use a background image across multiple monitors, it stretches it so that half the image shows up on my top three monitors, and about a third of the bottom of the image shows up on my small monitor down to the right. What you need to do is construct a callage of suitably scaled images. Use a shell script and ImageMagick or GraphicsMagick. I used to do this for my old multimonitor setup. Here we go: https://github.com/cameron-simpson/css/blob/main/bin/mkwall That (a) was for a '+ + +' or similar setup and (b) does some caching of the constructed wallpapers for performance. But the GraphicsMagick calls are in there for you to adapt. See the "Multiple images - assemble into montage" part. The "xrandr" command reports on all the screens on your current display, and can be quite useful for querying its current geometry.

If you wish it fixed, move the tablet up alongside screen #3 with bottoms flush. Then your untouchable space will be limited to space above the top of the tablet. Alternatively, relocate the leftmost screen over or under screen #2. Hopefully, the screenshots I uploaded can help with understanding, if help is needed.

Weird multiple display issue
Howdy - I have a multi monitor machine. The displays are set up like this: + + + + So I have three large monitors and a smaller tablet below the far right monitor. The weird thing is, it seems like the desktop THINKS my screen looks like this: + + + + + + So what happens is, when I do something like use a background image across multiple monitors, it stretches it so that half the image shows up on my top three monitors, and about a third of the bottom of the image shows up on my small monitor down to the right. Also, and this is the real problem, when I choose to rearrange my desktop icons, it distributes them across the left side of my left monitor and down across the nonexistent left bottom screen it seems to think is there. So my desktop icons disappear. About half of them appear to be placed under the leftmost monitor, but there's no monitor under that top monitor. I've posted pix of what my desktop looks like, and what I see when I capture a screenshot. https://imgur.com/a/gUBsgML In the screenshot, I have Chrome maximized on all four physical screens. As you can see from the screenshot, there is empty virtual desktop space below the left and center physical screens. You can see that my desktop icons are in that empty space. But I can't see them on the physical screens. Anyone know how to fix this so that my desktop icons don't disappear off the bottom of my screen? Thanks!
