How to install Vanilla Gnome on Ubuntu 18.04

While Ubuntu’s move back to Gnome has been celebrated, the default desktop theme is still very much modeled after Unity. For Gnome purists that’s not good enough.

Fundamental to Linux distributions, we are capable of having complete control over our desktop environment. This makes it easier to switch to Gnome native instead of being forced to use Ubuntu’s custom theme.

Install Gnome Session

  1. Open a Terminal window
  2. Install gnome-sessions
    sudo apt install gnome-session
  3. Enter ‘Y’ to install the required packages
  4. Log out of your account

Set the Gnome 3 Vanilla Theme as Default

Before we can switch the new desktop and theme, we need to install the Vanilla Gnome theme.

  1. Open a terminal window.
  2. Set the Gnome theme to default to the vanilla theme.
    sudo update-alternatives --config gdm3.css
  3. Log out of your account

Switching Desktop Environments

With gnome-sessions installed we can now select the desktop environment we would like to use. From the logon screen, you will see a gear Icon to the left of the Sign In button. When clicked a drop-down of available environments is presented.

Select the GNOME on Xorg desktop to log into your new Gnome Vanilla theme. Your selection will be saved for future logons.

After logging in you will notice that Ubuntu’s iconic sidebar is no longer displayed.  The color scheme and wallpaper remain the same, but all other Ubuntu desktop customization will be gone.
