Since the desktop icons are handled by an extension instead of Nautilus file browser, drag’n’drop action between desktop and file browser does no longer work.

Fortunately, a fork of the original Desktop Icons extension now is available with several enhancements, including Drag’n’Drop.

It’s called Desktop Icons NG, and features:

  • Drag’n’Drop, both inside the desktop, between desktop and applications, and nautilus windows
  • Allows to use “Open with…” option with several files
  • When hovering or clicking on an icon with a name too large to fit, it shows the full name
  • Doesn’t hang the compositor when there is too much activity in the desktop folder

sudo apt install chrome-gnome-shell gnome-shell-extension-prefs

2. Then go to extensions.gnome.org/…/desktop-icons-ng. Turn on the toggle icon and install the extension.

Don’t see the toggle icon? Click the link to install browser extension and refresh the web page.
