I was experimenting with different DEs.
I started with the Fedora Cinnamon spin
I tested:
GNOME
GNOME Classic
KDE
Deepin
And have decided to stick with GNOME and the Dash to panel addon.
How do I do about safely removing all the non GNOME environments whilst keeping my login manager and system bootable.
A cursory google search suggests
dnf swap
for moving between 2 environments.
But I want to delete:
Ratpoison (basic-desktop-environment)
Cinnamon
KDE
Deepin
Not switch.
