Is this how multiple monitors should work under X?

Wayland doesn’t include the first monitor in the second one.

Is this perhaps because of my window rules? I’d love to know which one, if so.

I suspect nobody has responded because it is not clear what you are asking. The subject mentions X and then you mention Wayland. You also don’t state which version of Frameworks, Plasma, and X you are using, nor the sizes of the two monitors, nor what you are trying to accomplish. I have two identical monitors, and they are set up side by side in either X or Wayland.
Also (and this is not much more than a guess) I don’t believe the windows rules have anything to do with how the two monitors are presented, just with how windows are drawn, wherever they get placed on the monitor(s).

@ostroffjh, I wanted to be able to use two monitors under X in order to use more windows. At some point, I had accidentally dragged one monitor over the other, and didn’t realize that I could simply drag it away from it.

Imagine that the 1440p monitor pictured is the 4K one, and that the 1440p one is in the top-left corner of the 1440p one:

I forgot, it appears, to include the images which would make mentioning that window rule relevant. I should have stated that with the “No window title and border” rule set to “Force” and “No” , even the desktops themselves have a window border. This is expected, though, so I don’t know why I mentioned it.

Sorry, but it’s not clear whether you still have a problem or not. It seems like you did discover that you can just drag one of the monitors to be next to the other instead of being on top of it. If so, is there anything else you need?

No, @ostroffjh, it seems to be okay. I have other issues with multiple monitors, but those will require different posts when I can be bothered to fix them. The other info was just added for myself. I would have put it in

but there’s a post edit limit, so


was the best I could think of.

Thanks lots.
