On 18.04 LTS a mounted internal disk (other than the boot disk) and a mounted share included in fstab
appear on the desktop without further intervention.
This appears not to be the case with 20.04.1.
The drives are perfectly selectable from within nautilus
and are mounted in /media/
.
Is this the new norm or have I missed a trick somewhere along the way? This is a vanilla installation of 20.04.1 from scratch on a new PC.
I found one that works. You do need to make sure that no other Desktop Icon extensions are enabled.
Go to https://extensions.gnome.org/extension/2087/desktop-icons-ng-ding/ and enable it to show those mounted drive icons on the desktop.
Example showing them enabled:
