How to Install GNOME 46 on Linux Mint 22

Linux Mint is built on Ubuntu and ships with the Cinnamon desktop environment by default — a deliberate choice by the Mint team to offer a stable, familiar interface. But some users want access to GNOME 46, the modern desktop environment that powers Ubuntu's default experience and many other major distributions. Understanding what that installation actually involves — and what trade-offs come with it — matters before you run a single command.

What Is GNOME 46 and Why Would You Want It?

GNOME 46 is a major release of the GNOME desktop environment, introducing refinements to Files (Nautilus), improved search performance, better remote desktop support, and accessibility enhancements. It's the desktop that ships with Ubuntu 24.04 LTS.

On Linux Mint 22 — which is based on Ubuntu 24.04 LTS — GNOME 46 sits in the underlying package repositories. That's the key detail: the packages exist, but Mint doesn't surface them through its default setup.

⚠️ Important distinction: Linux Mint 22 is based on Ubuntu 24.04, not Ubuntu 22.04. Despite the version number similarity, "Mint 22" and "Ubuntu 22.04" are different bases. This matters because the available GNOME packages align with Ubuntu 24.04's repositories.

Before You Start: What to Know About Installing GNOME on Mint

Installing GNOME 46 alongside Cinnamon is generally possible, but it introduces variables that affect how smoothly things go:

• Desktop environment conflicts — Some GNOME components can clash with Mint-specific tools, theming, or configuration utilities.
• Login manager behavior — Mint uses MDM or LightDM; GNOME typically prefers GDM3. Switching display managers changes how the login screen behaves.
• Package bloat — A full GNOME installation pulls in dozens of dependencies, some of which may overlap or conflict with existing Mint packages.
• Mint's own tools — The Mint Update Manager, Timeshift integration, and system tray applets are Cinnamon-native. They may not behave as expected inside a GNOME session.

None of these are blockers, but they're meaningful variables depending on how you use your system.

How to Install GNOME 46 on Linux Mint 22

Step 1: Update Your System First

Always start with a full system update before adding a new desktop environment.

sudo apt update && sudo apt upgrade -y 

Step 2: Install GNOME

You have two installation options depending on how complete an environment you want:

Option A — Full GNOME desktop (includes all GNOME apps):

sudo apt install gnome 

Option B — Minimal GNOME shell only (lighter footprint, fewer bundled apps):

sudo apt install gnome-shell 

The gnome metapackage installs the complete suite including GNOME Calendar, Maps, Photos, and other applications. The gnome-shell package gives you the core shell without the full application ecosystem — useful if you want GNOME's interface but plan to use apps from other sources.

Step 3: Install GDM3 (Optional but Common)

GNOME works most reliably with the GDM3 display manager. During installation, you may be prompted to choose between GDM3 and your existing display manager. If not, you can install it manually:

sudo apt install gdm3 

When prompted to choose a default display manager, selecting GDM3 gives the most native GNOME experience. Keeping LightDM is also viable — you'll just see a different login screen.

Step 4: Reboot and Switch Sessions

After installation, reboot your system:

sudo reboot 

At the login screen, look for a gear icon or session selector (typically near the password field). Click it to switch from your Cinnamon session to GNOME before logging in.

🛠️ After Installation: What to Expect

If you want to extend GNOME's functionality — adding a taskbar, adjusting fonts, tweaking animations — install GNOME Tweaks and GNOME Extensions Manager:

sudo apt install gnome-tweaks gnome-shell-extension-manager 

Removing GNOME If Something Goes Wrong

If the installation causes conflicts or you decide GNOME isn't right for your workflow, you can remove it:

sudo apt remove gnome && sudo apt autoremove 

If you switched to GDM3 and want to return to LightDM:

sudo dpkg-reconfigure lightdm 

Then reboot and select your Cinnamon session at login.

The Variables That Determine Your Experience 🖥️

How well GNOME 46 runs on Linux Mint 22 depends on factors specific to your machine and habits:

• RAM and GPU — GNOME's compositor and animations are more resource-demanding than Cinnamon, particularly on systems with 2–4GB RAM or integrated graphics with limited VRAM.
• Whether you use Mint-specific tools — Users who rely heavily on Timeshift's GUI, the Mint Update Manager, or System Settings may find the GNOME session less integrated.
• Full install vs. shell only — A minimal gnome-shell installation carries fewer conflict risks than the full gnome metapackage.
• How comfortable you are troubleshooting — Running two desktop environments side by side on Mint is workable, but it's not the same as a clean GNOME-native distribution like Ubuntu or Fedora.

Some users run GNOME 46 on Mint 22 without issue. Others find that certain Mint utilities don't translate cleanly into the GNOME session, or that display manager switching causes login screen quirks. The outcome depends heavily on your specific hardware configuration, which applications you depend on daily, and how much you're willing to adjust your workflow or troubleshoot edge cases.
