If you encounter dependency conflicts during installation, try using alternative installation methods with specific flags:

sudo dnf groupinstall "KDE Plasma Workspaces" --nobest --skip-broken

Step 4: Configure Display Manager

KDE Plasma uses SDDM (Simple Desktop Display Manager) as its primary display manager. Install and enable SDDM to provide proper login functionality:

sudo dnf install sddm -y
sudo systemctl enable sddm

The SDDM configuration ensures proper graphical login capability and desktop environment selection. This display manager provides better integration with KDE Plasma compared to alternative options like GDM or LightDM.

Verify the display manager service status to ensure proper configuration:

sudo systemctl status sddm

Step 5: Set Graphical Target

Configure your system to boot into graphical mode by default:

sudo systemctl set-default graphical.target

This command ensures your system automatically starts the graphical interface upon boot, eliminating the need for manual intervention. The graphical target configuration is essential for workstation environments where users expect immediate desktop access.

Verify the current default target to confirm successful configuration:

sudo systemctl get-default

The output should display “graphical.target” indicating proper configuration.
