Just FYI: The Desktop Environment is called Cinnamon (also used by Linux Mint), so what you are using the the Fedora Cinnamon spin... https://spins.fedoraproject.org/cinna...

how did you delete it? Did you know that you can revert any dnf transaction?

  1. sudo dnf history
  2. sudo dnf history list <ID-number>, e..g. sudo dnf history list 20
  3. sudo dnf history undo <ID-number>, e..g. sudo dnf history undo 20

or simply sudo dnf history undo last (things like last-1 work too)

very welcome. Take a look at the capabilities of dnf, it's a very powerful tool. To start with, check out dnf search ... e.g. dnf search power, or even better dnf search 'power manager' and dnf info ..., e.g. dnf info gnome-power-manager.
