How to remove GNOME Shell from Ubuntu 20.04 LTS to install other desktop environment from scratch?

  • 772

I have just installed the final version of Ubuntu 20.04 LTS desktop system from ubuntu-20.04-desktop-amd64.iso.
After two days of testing I completely do not like its graphical interface - the GNOME Shell.
Even installation of GNOME Flashback does not help either.

So I want to completely remove the GNOME Shell with all its trails from my system without re-installation.
Just want to start from scratch like it was approximately if I have installed Ubuntu from minimal network boot ISO.

gnome gnome-panel productivity gnome-shell 20.04

sudo apt autopurge

    Then one can install any desktop environment of interest with commands like:

    • Cinnamon - sudo apt install cinnamon-desktop-environment
    • KDE as in Kubuntu - sudo apt install kubuntu-desktop^
    • MATE as in Ubuntu MATE - sudo apt install ubuntu-mate-desktop^
    • Unity - sudo apt install ubuntu-unity-desktop
    • Xfce as in Xubuntu - sudo apt install xubuntu-desktop^

    then reboot, select newly installed desktop session and login to it.

    Note: this method is applicable for Ubuntu 21.04 and 21.10 too.

  2. After a former minimal-install followed by just 'lxde' [/usr/sbin/lightdm entry in file /etc/X11/default-display-manager] I unfortunately got 'gdm3' when performing a full upgrade from 18.10 to 19.04 and this persisted till 20.04. Eventually I removed 'gdm3'. Furthermore I had to sudo apt-get remove ‘gnome-shell‘ and ‘ubuntu-session‘. After this I got rid off all left free gnome-stuff with a simple sudo apt-get-autoremove.
