sudo dnf update
sudo dnf install @kde-desktop-environment

Beta installation considerations include potential system instability, compatibility issues with existing applications, and the possibility of data loss in extreme cases. Users should maintain current backups and avoid beta installations on critical systems requiring maximum reliability.

Reverting to stable releases requires disabling the beta repository and performing a distribution synchronization:

sudo dnf copr disable @kdesig/kde-beta
sudo dnf distro-sync

Post-Installation Configuration

Display Manager Configuration

Display manager selection significantly impacts the login experience and system integration quality. While Fedora systems typically use GDM (GNOME Display Manager) by default, KDE Plasma benefits from SDDM (Simple Desktop Display Manager) integration.

Switch to SDDM using systemctl commands that disable the current display manager and enable SDDM:

sudo systemctl enable --force sddm.service
sudo systemctl disable gdm

SDDM benefits include better KDE Plasma integration, improved theme support, and enhanced session management capabilities specifically designed for Plasma environments. The force option ensures SDDM replaces any existing display manager configuration without conflicts.

Display manager conflicts occasionally occur when multiple display managers remain enabled simultaneously. Proper service management through systemctl prevents these conflicts while ensuring reliable system startup and user authentication processes.

Session Selection and Login

Session selection procedures vary depending on the installed display manager. GDM users must click the gear icon at the bottom-right of the login screen to access session options, while SDDM provides direct session selection through dropdown menus.

Available session types typically include Plasma (X11), Plasma (Wayland), GNOME, and potentially other installed desktop environments. Wayland sessions offer improved security and performance for supported hardware, while X11 sessions provide broader application compatibility.

Graphical target configuration ensures the system boots into graphical mode by default:
