I used to use gsettings set org.gnome.desktop.background show-desktop-icons false
to remove desktop icons from Ubuntu 18.04. But this no longer works on Ubuntu 20.04. Why is it not working?
Edit
I don't want other tools that would help me achieve the goal. I just want to know why its not working.
Rather than use the command line, perhaps the GUI interface would be better:
sudo apt install gnome-tweaks
Changes take effect instantly.
Hope this helps.
