I want to install another DE on Ubuntu 18.04 (gnome edition). I have done this and the display/login manager used now is lightdm and it's using the DE I selected. What I want now is to delete any remnants of gnome and its dependencies without breaking the system. I tried: 1. removing the ubuntu-desktop metapackage Code: apt purge ubuntu-package && apt autoremove But no dependencies where deleted. I am assuming stuff like gdm3 or gnome-shell will be included at least. 2. same as number 1 except I was removing gnome-shell package. Only 4 or 5 packages were auto-removed. Knowing gnome, I'm sure there's more that should've been included. I don't want to use the server edition as my desktop can only access the net via WiFi and server edition can't see my WiFi card during installation. Any ideas on how it's done? Thanks!
