Warning on GNOME 40
The tutorial is designed to upgrade your Ubuntu system to the latest GNOME 40 using an untrusted PPA. The PPA that will be installed is well known and is genuinely safe from anything malicious. However, this isn’t to say it’s safe to use without the possibility of unstable updates breaking your system.
Be prepared and have backups when installing and updating any future packages relating to GNOME 40 from this PPA or any alternative installation method you may choose.
Prerequisites
- Recommended OS: Ubuntu 20.04
- User account: A user account with sudo or root access.
Update Operating System
Update your Ubuntu operating system to make sure all existing packages are up to date:
sudo apt update && sudo apt upgrade -y
The tutorial will be using the sudo command and assuming you have sudo status.
To verify sudo status on your account:
sudo whoami
Example output showing sudo status:
[joshua@ubuntu ~]$ sudo whoami
root
To set up an existing or new sudo account, visit our tutorial on adding a User to Sudoers on Ubuntu.
To use the root account, use the following command with the root password to log in.
su
Install Required PPA for GNOME 40
First, you will need to install two PPA’s to install GNOME 40 successfully. The PPA’s are all from the same maintainer Taha Nouibat.
First, install the “x11” repository to fix gnome-shell dependencies.
sudo add-apt-repository ppa:devacom/x11 -y
Secondly, install the GNOME 40 PPA, which is needed for some of the required dependencies.
sudo add-apt-repository ppa:devacom/gnome-40 -y
Note, you may see error pop-ups. You can ignore these as they will disappear once you install the new GNOME 40.
Example:
Once you have finished importing, run an update to reflect the new additions.
sudo apt-get update
Install GNOME 40 Desktop Environment
With the three separate PPA’s installed and updated in your repository list, the first step is to install gnome-shell.
sudo apt install ubuntu-desktop gnome-shell gnome-control-center
Example output:
Type “Y,” then press the “ENTER KEY” to continue.
Next, the repositories have added extra dependencies that need updating. Before rebooting, you should update these packages.
sudo apt upgrade
Example output:
Type “Y,” then press the “ENTER KEY” to continue.
Note this may take a while. There are lots of packages to upgrade and install. If you cannot see any packages to update, you may have skipped the apt update command re-run, and they should appear.
Once done, you need to reboot your system for the changes to take effect fully.
sudo reboot
First Look GNOME 40 Desktop Environment
Once you have restarted your Ubuntu system, you will first come to a new login screen entirely different from a lovely new theme.
Example:
DO NOT LOG IN STRAIGHT AWAY.
First, you need to change the display manager. This is done by clicking the configuration button in the top right-hand corner of the login window, to the right of your username, and selecting either “Ubuntu on Wayland” or “Ubuntu on Xorg” instead of “Ubuntu.”
The summarise Xorg is tried and true. The choice is optional between Xorg and Wayland. However, being very stable with applications, Xorg can be more unsafe and lower in performance. Wayland has increased performance when applications are tuned for it and is much safer. However, given its new and still being adapted, many instabilities occur, leading many to use Xorg still instead.
Example:
Once logged in, you will notice quite a few UI changes to the taskbars and icons.
Example:
The Applications have had a major facelift along with many of the default applications installed with GNOME.
Example:
Verify GNOME 40 Desktop Environment
Typically, you can go to the “About” in the GUI settings to find system information.
Alternatively, you can confirm the installation. A handy package to install is Neofetch.
To install this package, use the following command in your terminal.
sudo apt install screenfetch -y
Once installed, run the following command in your terminal.
screenfetch
Example output:
Congratulations, you have installed the latest GNOME 40 on Ubuntu 20.04 LTS Focal Fossa.
How to Update GNOME 40 Desktop
Run the standard apt command for future updates for the GNOME 40 desktop environment and Ubuntu 20.04 default packages.
sudo apt update
When updates are available, it is the same process to upgrade.
sudo apt upgrade
Comments and Conclusion
In the tutorial, you have learned how to install the latest GNOME 40 Desktop Environment using the PPA provided by Taha Nouibat.
Overall, GNOME 40 will look very different once you change from the default GNOME 38. Some of the noticeable changes are rounded window corners, smoother animations which give it a more modern look amongst many other changes.
Another question is should you upgrade to this? Possibly the work is already started on GNOME 41, which is very unstable. Still, GNOME 40 from this PPA has matured and looks semi-stable, but make sure to have backups when working with any alternative desktop environment.
