The following commands set the Nemo file manager to handle the desktop:
> gsettings set org.gnome.desktop.background show-desktop-icons false
> gsettings set org.nemo.desktop show-desktop-icons true
But there seems no such command as "gsettings set org.thunar.desktop show-desktop-icons true"
to set thunar to handle the desktop. How do I do it then? Thanks.
Well, my Thunar is of version 1.6.2 with Xfce 4.12 (https://wiki.xfce.org/releng/4.12/roadmap/thunar). Looks like the feature didn't get implemented.
