Drag'n'drop files Desktop <-> File manager with 20.04 LTS doesn't work ; it worked on 18.04 LTS [duplicate]

In Ubuntu 20.04, on the desktop, there is a number of actions I wish I could do, such as, by order of importance :

• use keyboard shortcuts such as select all, copy / paste.
• use drag & drop with icons
• deactivate the "mouse over" highlight, and restrict the clicking area to only the icon, not the surrounding square

To put it simply, I'd like to have the exact same features as offered by the desktop of Ubuntu 18.04 (probably related to a specific version of GNOME, and not Ubuntu itself).

Am I missing something obvious here? I actually see no reason why those actions are removed or deactivated on the desktop, since they all work in any Nautilus window.

Unfortunately, desktop icons are completely broken (which is quite unexpected in a LTS release of Ubuntu) as instead of the file-manager (Nautilus) handling the desktop items, now a GNOME Shell extension handles them.

See this bug report: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-desktop-icons/+bug/1813441

A workaround involving replacing the file-manager is described here: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-desktop-icons/+bug/1813441/comments/14. To do that, follow the steps below.

1. remove gnome-shell-extension-desktop-icons
2. install nemo
3. make Nemo handle desktop icons

The reason behind this change in experience compared to older Ubuntu releases is that the GNOME developers have relieved recent versions of Nautilus (aka (GNOME) Files, the default file-manager application) from handling the the desktop and the items on it. The rationale behind this decision can be found here: https://gitlab.gnome.org/GNOME/nautilus/-/issues/158. The standard unmodified GNOME desktop comes without the desktop icons feature altogether.

To mitigate the issue, Ubuntu developers have shipped Ubuntu 20.04 LTS (in fact, it's happening since the Ubuntu 19.04 release) with a GNOME Shell extension called 'Desktop Icons' (package name: gnome-shell-extension-desktop-icons) which handles the desktop and provides the desktop icons. But currently the extension offers only a limited set of features, so you would find many of the standard desktop features missing.

A workaround would be to use a different and slightly more featureful extension, called Desktop Icons NG (DING) by Sergio Costas (a fork of the Desktop Icons extension). Note that you need to disable the pre-installed Desktop Icons extension first (using the 'Extensions' application, for example).

Desktop Icons NG (DING) offers some extra features compared to the default one, for example

• Drag-and-Drop, both inside the desktop, between desktop and applications, and nautilus windows.
• Allows to use the '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.
• Usual keyboard shortcuts to cut/copy, paste, select all, delete (both move to trash and delete permanently).
• Option to show a 'delete permanently' action in the context menu (right-click menu).
• Option to show removable drives and network drives on the desktop.
• Option to choose alignment for new icons.

The current GNOME "desktop" looks more like a pain, not the real desktop. It breaks habits and classic desktop user-experience.

And what is even worse is that Ubuntu 20.04 LTS is an LTS release. So you have a good chance of being stuck with anything but a fully functional desktop for the next 5 years.

Thus you may consider ditching the GNOME desktop environment altogether and choose a normal fully functional alternative. My method of achieving this is presented in this Q&A:
How to remove GNOME Shell from Ubuntu 20.04 LTS to install other desktop environment from scratch?
My favorite is MATE DE, but your choice may be different.

According to this push request by GNOME desktop icons dev https://gitlab.gnome.org/World/ShellExtensions/desktop-icons/-/merge_requests/174 it should be working partially. At time of writing, applying the patch results in moving the desktop file/folder to trash, but no difference with shift+delete (it also moves the file to the trash)

To apply the patch immediately instead of waiting to the release of the updated package, you can follow this steps.

If you followed the answer by Mee that pointed to an old workaround here https://gitlab.gnome.org/GNOME/nautilus/issues/158#alternative-solution, you may need these extra steps:

rm ~/.config/autostart/nemo-autostart-with-gnome.desktop
sudo apt-get purge nemo
sudo apt autoremove -y
sudo apt install --reinstall gnome-shell-extension-desktop-icons

Then you need to edit a couple of files following the steps below:

1. In a Terminal window, run

   sudo -H nautilus
   

2. Navigate to /usr/share/gnome-shell/extensions/desktop-icons@csoriano/.

3. Open createFolderDialog.js with gedit or a similar text-editor.

4. Copy/Paste https://gitlab.gnome.org/World/ShellExtensions/desktop-icons/-/raw/8ba06e3f456e211dfeace27bb27221cd375b65de/createFolderDialog.js

5. Open desktopGrid.js with gedit or a similar text-editor.

6. Copy/Paste https://gitlab.gnome.org/World/ShellExtensions/desktop-icons/-/raw/8ba06e3f456e211dfeace27bb27221cd375b65de/desktopGrid.js

Restart and you're done!
