I have the extension turned OFF (see ❶), but still the icons are there (see ❷)!
I can get rid of them if I uninstall the extension with
sudo dpkg -r --force-depends gnome-shell-extension-desktop-icons
But they'll come back with an upgrade. I can force them not to like:
sudo apt-mark hold gnome-shell-extension-desktop-icons
But then I get a massive red ⛔ icon permanently telling me my system is broken.
Why won't it behave? Is there a way to fix it?
