GNOME 46 can give a Linux Mint system a modern, streamlined desktop with a clean Activities overview, improved settings, better file management, and a polished workflow. Since Linux Mint normally ships with Cinnamon, MATE, or Xfce, installing GNOME requires adding the correct packages, choosing a display manager, and understanding how Mint components may behave alongside GNOME components.

TLDR: GNOME 46 can be installed on Linux Mint by using the Ubuntu package base available to the installed Mint release, then selecting GNOME at the login screen. The safest approach is to install gnome-session, gdm3, and key GNOME applications rather than replacing the whole system blindly. A Timeshift snapshot should be created first, because desktop environments share settings, themes, and display manager components. After installation, the user logs out, chooses GNOME, and signs in to complete the setup.

Before Installing GNOME 46 on Linux Mint

Linux Mint is designed around a stable desktop experience, especially with Cinnamon. GNOME 46 is a different environment with a different workflow, so the installation should be treated as a desktop expansion rather than a simple theme change. GNOME uses the Activities overview, dynamic workspaces, a top panel, and a separate extensions system, while Cinnamon relies on a more traditional panel and menu layout.

There is also an important version detail. Linux Mint 22 is based on Ubuntu 24.04 LTS, which includes GNOME 46 packages in its repositories. If the installed system is actually Linux Mint 21.x, based on Ubuntu 22.04, GNOME 46 is not normally available from the default repositories. In that case, the recommended path is upgrading to a Mint release based on Ubuntu 24.04 rather than forcing GNOME 46 from unsupported repositories.

Recommended preparation:

  • Create a Timeshift snapshot before installing another desktop environment.
  • Update the system fully before adding GNOME packages.
  • Ensure enough disk space; GNOME packages and dependencies may require several hundred megabytes.
  • Expect duplicate applications, such as two file managers, terminals, settings tools, and text editors.
  • Use official repositories where possible to avoid package conflicts.

Step 1: Update Linux Mint

The system should be updated before any desktop environment installation. This reduces dependency conflicts and ensures the package manager has the newest package lists. The following commands update the local package index and upgrade installed packages:

sudo apt update
sudo apt upgrade

If the upgrade installs a new kernel, display stack component, or graphics-related package, a reboot is sensible before continuing:

sudo reboot

After rebooting, the system is ready for the GNOME installation. This is also the best point to create a Timeshift snapshot if it has not already been created.

Step 2: Install Core GNOME 46 Packages

The cleanest method is to install GNOME’s core session and display manager without pulling in a large amount of branding or unnecessary applications. On Linux Mint 22, the following command installs the GNOME Shell session, GNOME display manager, GNOME Control Center, Nautilus file manager, and GNOME Terminal:

sudo apt install gnome-session gdm3 gnome-shell gnome-control-center gnome-terminal nautilus

During installation, the package manager may ask which display manager should be used by default. Linux Mint normally uses LightDM, while GNOME is designed to work best with GDM3. For the most complete GNOME experience, gdm3 should be selected.

If the prompt does not appear, or if the display manager needs to be changed later, the following command can be used:

sudo dpkg-reconfigure gdm3

The user can then select gdm3 from the menu. GNOME works more naturally with GDM because it integrates well with GNOME Shell, lock screen behavior, user switching, and Wayland sessions.

Step 3: Optional Full GNOME Application Set

The minimal installation provides the GNOME session and essential tools, but some users may want a fuller GNOME desktop. Additional applications can be installed with:

sudo apt install gnome-calendar gnome-clocks gnome-weather gnome-maps gnome-text-editor file-roller eog evince

This adds common GNOME utilities, including a calendar, clocks, weather, maps, archive manager, image viewer, and document viewer. However, Linux Mint already includes many equivalent tools. Installing every GNOME application is not required and may create duplicate menu entries.

Some users may be tempted to install a large meta-package such as gnome or gnome-core. While this can work, it may install many packages that are not necessary on Mint. A controlled package list gives the user a cleaner setup and makes it easier to remove GNOME later if desired.

Step 4: Reboot and Select GNOME

Once the packages are installed, the system should be rebooted:

sudo reboot

At the login screen, the user should select the session menu. Depending on the display manager theme, this may appear as a gear icon or a session selector near the password field. The session should be changed from Cinnamon or another Mint desktop to GNOME.

If multiple GNOME options appear, the most common choices are:

  • GNOME — usually the standard session, often using Wayland when supported.
  • GNOME on Xorg — useful for some NVIDIA systems, screen recording tools, remote desktop setups, or compatibility needs.
  • GNOME Classic — a more traditional GNOME layout if installed separately.

After selecting GNOME, the user can sign in. GNOME may take a few moments to build caches and initialize settings the first time it starts.

Step 5: Confirm the GNOME Version

After logging into GNOME, the installed version can be checked from the terminal:

gnome-shell --version

On a Mint release based on Ubuntu 24.04, the expected result should show GNOME Shell 46 or a closely related 46.x package version. The version can also be reviewed through Settings and the About section, though the terminal command is usually more direct.

Step 6: Adjust Themes, Fonts, and Appearance

GNOME uses its own appearance system, and Linux Mint themes may not behave exactly as they do in Cinnamon. The main visual settings can be changed from:

Settings > Appearance

To install GNOME Tweaks, which provides more control over fonts, startup applications, window buttons, and theme behavior, the following command can be used:

sudo apt install gnome-tweaks

GNOME Tweaks is especially helpful for users who want to modify titlebar buttons, enable additional theme options, or adjust font rendering. However, GNOME 46 is more restrictive with shell theming than older Linux desktops, so the most reliable customization method is through official appearance settings and well-maintained extensions.

Step 7: Install GNOME Extensions Support

GNOME extensions allow the desktop to be customized with features such as a dock, app indicators, workspace tools, and panel modifications. The extension manager can be installed with:

sudo apt install gnome-shell-extension-manager

After installation, the app can be launched from the application grid as Extension Manager. It allows users to browse, install, enable, disable, and configure GNOME Shell extensions.

Popular extension types include:

  • Dash to Dock for a persistent dock.
  • AppIndicator support for traditional tray icons.
  • Blur effects for visual customization.
  • Clipboard managers for productivity workflows.
  • Panel customization for users who prefer a more classic layout.

Extensions should be installed carefully. A broken or outdated extension can cause GNOME Shell glitches after updates. If GNOME behaves strangely, disabling extensions is often the first troubleshooting step.

Step 8: Handle Duplicate Applications

After GNOME is installed, the application menu may show tools from both Linux Mint and GNOME. This is normal. For example, the system may include both Nemo and Nautilus file managers, or both Mint settings tools and GNOME Settings.

In GNOME, Nautilus is the default file manager, while Cinnamon normally uses Nemo. Both can exist on the same system. Removing Mint applications is not necessary and may affect Cinnamon if the user wants to keep it available.

A practical approach is to keep both desktop environments installed until GNOME has been tested for several days. If GNOME becomes the preferred desktop, unused applications can later be removed carefully. Essential Mint packages should not be removed unless the user understands the dependency consequences.

Step 9: Wayland, Xorg, and Graphics Notes

GNOME 46 works well with Wayland on many modern systems. Wayland can provide smoother touchpad gestures, better fractional scaling support, and improved display handling. However, some proprietary NVIDIA configurations, remote desktop tools, screen capture apps, or older workflows may still work better on Xorg.

If a user experiences black screens, missing cursor behavior, screen sharing issues, or unusual graphics glitches, the GNOME on Xorg session should be tested from the login screen. This does not require reinstalling GNOME; it is simply another session option.

Step 10: Troubleshooting Common Installation Issues

If the system boots to a login screen but GNOME does not appear as a session option, the core session package may not have installed correctly. The following command can be used:

sudo apt install --reinstall gnome-session gnome-shell

If the login screen does not appear correctly after switching to GDM3, the display manager can be reconfigured:

sudo dpkg-reconfigure gdm3

If the user wants to return to Mint’s original display manager, LightDM can be selected instead, assuming it remains installed. If needed, it can be installed again:

sudo apt install lightdm slick-greeter

Then it can be selected with:

sudo dpkg-reconfigure lightdm

If GNOME becomes unstable after enabling extensions, the user can log into another session such as Cinnamon and disable extensions through Extension Manager, or reset GNOME Shell extension settings with:

gnome-extensions disable EXTENSION_NAME

How to Remove GNOME Later

If GNOME is no longer needed, it can be removed. The user should first log into Cinnamon or another non-GNOME session. Then the main GNOME packages can be removed with:

sudo apt remove gnome-session gdm3 gnome-shell gnome-control-center gnome-terminal nautilus
sudo apt autoremove

If the system should return to LightDM, it can be reinstalled or reselected:

sudo apt install lightdm slick-greeter
sudo dpkg-reconfigure lightdm

A reboot should then restore the normal Mint login flow:

sudo reboot

Removal should be done carefully because shared libraries and applications may be used by more than one desktop environment. The apt autoremove step should be reviewed before confirmation.

Final Thoughts

Installing GNOME 46 on Linux Mint can be a good choice for users who prefer GNOME’s clean workflow, Activities overview, Wayland support, and extension ecosystem. The safest method is to install the core GNOME session and supporting tools without replacing the entire Mint desktop stack. With a backup snapshot, careful package selection, and the correct login session, Linux Mint can run Cinnamon and GNOME side by side while the user decides which environment fits best.

FAQ

  • Can GNOME 46 be installed on Linux Mint based on Ubuntu 22.04?
    Not easily through official repositories. GNOME 46 is normally available on systems based on Ubuntu 24.04. For a Mint system based on Ubuntu 22.04, upgrading to a newer Mint release is safer than using unsupported repositories.

  • Will installing GNOME remove Cinnamon?
    No. Installing GNOME does not automatically remove Cinnamon. Both desktop environments can usually exist together, and the preferred one can be selected at the login screen.

  • Should GDM3 or LightDM be used?
    GNOME works best with GDM3, especially for lock screen integration, Wayland sessions, and user switching. LightDM can still be used if the user prefers Mint’s default login manager.

  • Why are there duplicate apps after installing GNOME?
    Mint and GNOME include different default applications. Duplicate file managers, terminals, settings tools, and text editors are normal when multiple desktop environments are installed.

  • Is Wayland required for GNOME 46?
    No. GNOME 46 can run on Wayland or Xorg. Wayland is modern and smooth on many systems, while Xorg may be better for certain NVIDIA drivers, screen sharing tools, or legacy workflows.

  • Is it safe to install GNOME extensions?
    Yes, but extensions should be installed selectively. Outdated extensions can cause GNOME Shell issues, especially after system updates.

  • Can GNOME be removed if it is not liked?
    Yes. The user can log into Cinnamon, remove the GNOME packages, reselect LightDM if desired, and run apt autoremove carefully.
