How to Install GNOME Desktop on Ubuntu 24.04

If you’re looking to switch your Ubuntu 24.04 system to a different desktop environment, installing GNOME Desktop is an excellent choice. GNOME offers a modern, clean, and highly customizable user interface that enhances your overall user experience. This guide will walk you through the process of installing GNOME on Ubuntu 24.04, whether you’re replacing the existing desktop or setting up a dual environment. Before you begin, ensure your system is up to date and has a stable internet connection. You should also have administrative privileges to run commands with sudo.

What You’ll Need

  • A computer running Ubuntu 24.04
  • Root or sudo privileges
  • Stable internet connection
  • Optional: Backup your data before making significant system changes

Step-by-Step

  1. Open a Terminal Window

    2. Press Ctrl + Alt + T or search for “Terminal” in your application menu to open a terminal window. This is where you’ll run all commands to install GNOME.

  2. Update Your System Packages

    3. Run the following command to ensure your system packages are current. This helps prevent conflicts during installation:

    sudo apt update && sudo apt upgrade -y

    This process may take some time depending on your system and internet speed. It updates the package lists and installs any available upgrades.

  3. Install GNOME Desktop Environment

    4. To install the full GNOME desktop environment, run:

    sudo apt install gnome-session gnome-shell ubuntu-gnome-desktop -y

    This command installs the core GNOME session, shell, and Ubuntu-specific GNOME packages. If you prefer a minimal GNOME setup, you could install just gnome-session and gnome-shell.

  4. Choose Your Display Manager

    5. During installation, you may be prompted to select a display manager. The display manager handles your login screen. You can choose between GDM3 (recommended for GNOME) or LightDM. Use the arrow keys to select and press Enter.

  5. Reboot Your System

    6. Once the installation completes, reboot your system to start using GNOME:

    sudo reboot
  6. Select GNOME at Login

    7. At the login screen, click the gear icon (or similar icon depending on your display manager) and select “GNOME” or “GNOME on Xorg”. Then, log in as usual.

  7. Verify Your GNOME Desktop

    8. After logging in, you should see the GNOME desktop environment. To confirm, open the terminal and run:

    echo $XDG_CURRENT_DESKTOP

    It should display “GNOME”.

Common Mistakes

  • Not updating packages before installation: Always run sudo apt update to avoid conflicts.
  • Choosing the wrong display manager: For GNOME, GDM3 is recommended. Using LightDM may cause compatibility issues.
  • Installing incomplete packages: Ensure you include all necessary packages like gnome-session and gnome-shell.
  • Forgetting to reboot: Changes only take effect after a reboot.

Tips

  • Backup your data: Always back up important files before system modifications.
  • Try a live session first: You can test GNOME without installing by booting from a live Ubuntu ISO with GNOME live environment.
  • Customize GNOME: Use GNOME Tweaks to personalize your desktop after installation.
  • Remove old desktop environments: If replacing, consider removing other desktop environments to free up space, e.g., sudo apt remove kubuntu-desktop.

Troubleshooting

If the installation does not go as planned or GNOME does not load correctly, try the following:

  • Reboot in recovery mode: Restart your system and select recovery mode from the GRUB menu. From there, you can attempt to fix broken packages or revert changes.
  • Reinstall GNOME: Sometimes, re-running the installation command can resolve issues:
    • sudo apt install --reinstall gnome-session gnome-shell ubuntu-gnome-desktop
  • Switch display manager: If GNOME login fails, you might need to reconfigure your display manager:
    • sudo dpkg-reconfigure gdm3

    Then select GDM3 and reboot.

  • Check logs: Review system logs to identify errors:
    • journalctl -xe

If issues persist, consider seeking help on Ubuntu forums or community support channels, providing details of your system and error messages.
