I want to delete the Gnome desktop environment.
What command is used for an elimination complete?
I use this command but don't get the effect desired.
# apt-get install task-gnome-desktop
"install" won't remove. You want "remove" or "purge".
But don't even bother uninstalling it (unless you need the drive space); just install a different DE of your preference, and then on your login screen you can choose which DE to use. Install several DEs, and swap between them whenever you feel like.
