One of the limitations of GNOME's current multi-monitor handling is that the same background is used across the displays. For those that want to enjoy per-monitor background selection, some experimental / proof-of-concept code is now working to allow such per-monitor backgrounds to work with the modern GNOME desktop.

Open-source developer and Phoronix reader Gianluca Masci wrote in to share his proof-of-concept work for allowing per-monitor wallpapers with the GNOME Shell. This brings the needed architectural changes for independent, per-monitor backgrounds within the GNOME Shell.

As part of this work is also a configuration tool for GNOME Shell in handling the per-monitor background selection.

The work hasn't yet reached the stage of an upstream merge request, but for now the PoC Code is hosted via [1]this GitHub repository with all the details. This development is also noted as AI supported in its creation.
