Install GNOME minimal on Ubuntu 20.04


The “Vanilla Gnome” version is a clean GNOME desktop installation. It lacks most of the software you would expect as default, however the desktop resource requirements are minimal.

  1. To install the minimal GNOME desktop environment, use your system’s package manager to install the GUI and gdm3 window manager. 
    $ sudo apt install gnome-session gdm3
  2. After installation is complete, reboot your system and you will be presented with a GNOME login. 
    $ reboot

Install GNOME full desktop on Ubuntu 20.04

The “Full version” of GNOME will come with more software by default. Some users may find it bloated, and others may find that it comes with all the necessary things they need. The only thing to keep in mind is that this version will consume a bit more system resources than the minimal version.

  1. The easiest way to install full GNOME desktop is by using the tasksel command. First ensure that the tasksel command is available on your system: 
    $ sudo apt install tasksel
  2. Next, use the tasksel command to install GNOME desktop:

    $ sudo tasksel install ubuntu-desktop
  3. All done. Reboot your Ubuntu 20.04 system: 
    $ sudo reboot
