I don’t if it’s possible since I didn’t see any settings in either it’s config file / in it settings ! I want my background image to not duplicate per pane !
Unfortunately not with KDE after 15 + years on my personal wish list of things as well. I got a bit excited with newer 6.x option to at least reproduce the configuration across all of them the same, but it just means each does the same thing for a single pane still, and does not allow for combining for a single image.
I have some really lovely 11520x2160 3x4k wallpapers I’d love to use across my 3x displays. When trying other DE’s I noticed I think Cinnamon or Mate would, but still not KDE oddly.
i may misunderstand the question, but since @mikus mentioning splitting a wallpaper over three displays, my solution is just a little imagemagick with bash, to simply cut a given image into three same sized parts, and set them on every display individually.
here’s the script, in case it helps somebody:
#!/bin/bash
# Input file
input_file="$1"
# Get image dimensions
width=$(identify -format "%w" "$input_file")
height=$(identify -format "%h" "$input_file")
# Calculate the width of each part (since the height remains unchanged)
part_width=$((width / 3))
# Split the image horizontally into three equal parts
convert "$input_file" -crop ${part_width}x${height}+0+0 +repage part1.jpg
convert "$input_file" -crop ${part_width}x${height}+${part_width}+0 +repage part2.jpg
convert "$input_file" -crop ${part_width}x${height}+$(($part_width * 2))+0 +repage part3.jpg
echo "Image split into 3 horizontally tiled parts: part1.jpg, part2.jpg, part3.jpg"
simply use it by: script.sh yourwidescreenwallpaper.jpg
That’s pretty much exactly what I’d done for one or two I like, only now I do like it to change to random desktops periodically, and I simply didn’t want to do that for each 50-some large/wide images I have with no way to really coordinate them across each display in proper sequence.
What OP wants refers specifically to Konsole’s split views.
This could be a feature, and I doubt it would be very difficult to implement. It’d just be another option (per pane, per window).
I’d suggest filing a feature request bug at bugs.kde.org.
