CentOS Stream 10 now targets the v3 microarchitecture level on AMD/Intel 64-bit systems, which enables optimizations but also sets minimum hardware requirements. You can verify your CPU’s supported levels by running ld.so --help in the terminal.

Software Prerequisites

Ensure your CentOS Stream 10 installation includes these essential components:

• Fresh CentOS Stream 10 installation (minimal or server configuration)
• Root access or sudo privileges for system modifications
• Active internet connection for downloading packages (approximately 450MB for GNOME installation)
• Updated system packages to prevent compatibility issues

Network Configuration Verification

A stable internet connection is crucial for downloading GNOME packages and dependencies. Verify your network configuration by testing DNS resolution and repository access:

ping -c 3 google.com
dnf repolist

These commands confirm internet connectivity and ensure package repositories are accessible.

Pre-Installation System Checks

Verifying Current System State

Before installing GNOME, assess your current system configuration to understand the installation scope and identify potential issues.

Check the current system target to determine if you’re running in multi-user or graphical mode:

systemctl get-default

If the output shows multi-user.target, your system currently boots to command-line mode. After installing GNOME, you’ll change this to graphical.target.

Verify available disk space to ensure sufficient room for the installation:

df -h

The root filesystem should have at least 2GB of free space for the GNOME installation, though more is recommended for future updates and applications.

Package Group Assessment

CentOS Stream 10 organizes software into logical groups, making it easier to install complete desktop environments. Check available environment groups:

dnf group list

This command displays available installation options, including “Server with GUI,” which contains GNOME and essential desktop components. Understanding these groups helps you make informed decisions about which packages to install.

Step-by-Step GNOME Installation Process

System Update

Begin by updating your CentOS Stream 10 system to ensure all packages are current and compatible:

dnf update -y

This command downloads and installs the latest package versions, security patches, and kernel updates. The process may take several minutes depending on your internet connection and the number of available updates. If a kernel update is included, you may need to reboot before proceeding with the GNOME installation.

Installing GNOME Desktop Environment

The primary method for installing GNOME on CentOS Stream 10 involves using the “Server with GUI” package group, which includes GNOME 47 and all necessary supporting components:

dnf -y group install "Server with GUI"

This comprehensive installation includes:

• GNOME Shell desktop environment
• Display manager (GDM) for graphical login
• Essential applications like file manager and terminal
• System utilities and configuration tools
• Graphics and multimedia support libraries

The download size is approximately 450MB, with an installed size of around 1.8GB. Installation time varies based on system performance and internet speed, typically taking 10-30 minutes.

Monitor the installation progress and watch for any error messages. The package manager will automatically resolve dependencies and handle the complex installation process.

Configuring Graphical Boot Target

After successfully installing GNOME packages, configure your system to boot into graphical mode by default:

systemctl set-default graphical.target

This command creates a symbolic link from /etc/systemd/system/default.target to /usr/lib/systemd/system/graphical.target, ensuring your system starts the display manager and desktop environment on boot.

Verify the change was applied correctly:

systemctl get-default

The output should now show graphical.target, confirming your system will boot to the GNOME desktop.

System Reboot and First Graphical Boot

Restart your system to activate the graphical environment:

reboot

During the reboot process, systemd will start additional services required for the graphical environment, including the GNOME Display Manager (GDM). The first boot into GNOME may take longer than subsequent boots as the system initializes desktop services and user directories.

Post-Installation Configuration and Setup

Initial GNOME Welcome Screen

Upon successful boot, you’ll encounter the GNOME welcome screen, which guides you through essential configuration steps:

1. Language and Keyboard Layout Selection: Choose your preferred language and keyboard configuration for the desktop environment
2. Location Services Configuration: Decide whether to enable location-based services for weather, time zones, and other location-aware applications
3. Online Accounts Setup: Optionally configure integration with email, calendar, and cloud storage services
4. Privacy Settings: Review and adjust privacy preferences according to your requirements

Complete the initial setup by clicking “Start Using CentOS Stream 10” to access the full desktop environment.

User Account Configuration for GUI Access

While root can access the GNOME desktop, it’s recommended to create or configure regular user accounts for daily desktop use:

useradd -m username
passwd username
usermod -aG wheel username

These commands create a new user account, set a password, and add the user to the wheel group for sudo access. Regular users provide better security isolation and prevent accidental system modifications.

Essential Applications Installation

CentOS Stream 10 includes a minimal set of desktop applications. Install additional software based on your needs:

dnf install firefox libreoffice vlc

Note that some traditional desktop applications like GIMP, LibreOffice, and Inkscape have been removed from the default repositories as RHEL transitions to Flatpak distribution. For these applications, consider using Flatpak or EPEL repositories.

Advanced Configuration Options

GNOME Shell vs Classic Mode

CentOS Stream 10 includes both modern GNOME Shell and the traditional Classic mode interface. Switch between these modes at the login screen by clicking the gear icon before entering your password and selecting your preferred session type.

GNOME Shell provides a modern, streamlined interface with an activities overview and integrated search functionality. Classic mode offers a more traditional desktop layout with a taskbar and application menu, familiar to users transitioning from older desktop environments.

Remote Access Configuration

For remote GUI access, configure VNC or RDP services:

dnf install tigervnc-server
systemctl enable vncserver@:1.service

Set up a VNC password for secure remote connections:

vncpasswd

This configuration allows remote access to your GNOME desktop from other systems on the network.

Graphics and Display Optimization

CentOS Stream 10 uses Wayland as the default display protocol, with Xwayland providing compatibility for legacy X11 applications. For systems with graphics issues, you can temporarily switch to X11 by selecting “GNOME on Xorg” at the login screen.

Adjust display settings through GNOME Settings or using command-line tools:

gsettings set org.gnome.desktop.interface scaling-factor 1.25

This command increases the interface scaling for high-resolution displays.
