Different background for each workspace
In the past, setting the different backgrounds for each desktop was rather an easy thing to do.
I have not tried that for the past 2 years, and now I have been struggling for a few days to find a way to do it.
What is the "modern" way to set a different background for each workspace? Ubuntu 20.04 is in question.
You can use Walkpaper Gnome Extension.
Set different wallpaper for each workspace by having the wallpaper switch on workspace change.
