Hello everyone.

Recently I bought an external monitor for my laptop running plasma 5.23.1. I put the wallpapers on them such that they span across the two displays, which looks very nice. However, when I have to use my laptop on the go, my wallpaper is now cut in half and off-center, which really looks bad.
Therefore, I'd like to know if there is a way to automatically change my wallpapers depending on my display configuration. In that case, when I plug my monitor, it automatically loads my spanned wallpaper and applies it, and when I disconnect my monitor in goes back to my single screen wallpaper.
My best bet would be using a udev rule, but I am not knowledgeable enough to know how to properly use them (and if they even work with external monitors).

I hope there is a way to do that!
Thank you for helping.
