How do I switch from GNOME to KDE

First, we need to install KDE’s base and switch login managers. Open a terminal and run:

sudo dnf install -y sddm

sudo systemctl disable gdm
sudo systemctl enable sddm

sudo rpm -e --nodeps nobara-release-identity-workstation
sudo dnf swap -y nobara-release-workstation nobara-release-kde

sudo dnf groupinstall -y kde-desktop-environment --exclude=ffmpeg,ffmpeg-libs

Reboot:

sudo systemctl reboot

At the bottom left of the login screen you should see ‘Desktop Session: yada yada yada’. Click this and change it to ‘Plasma (Wayland)’ then login.

Open ‘konsole’ terminal:

Remove gnome:

sudo rpm -e --nodeps gnome-shell
sudo rpm -e --nodeps nobara-gnome-layouts

sudo dnf groupremove -y \
workstation-product-environment

sudo dnf remove -y \
gdm \
evince \
file-roller \
gedit \
gnome-extension-manager \
gnome-icon-theme \
gnome-shell-extension-arc-menu \
gnome-shell-extension-blur-my-shell \
gnome-shell-extension-clipboard-history \
gnome-shell-extension-custom-accent-colors \
gnome-shell-extension-dash-to-panel \
gnome-shell-extension-desktop-icons \
gnome-shell-extension-gamemode \
gnome-shell-extension-gesture-improvements \
gnome-shell-extension-pop-shell \
gnome-shell-extension-supergfxctl-gex \
gnome-shell-extension-user-theme \
gnome-shell-extension-wireless-hid \
gnome-shell-nobara-theming \
gnome-startup-applications \
gnome-tweaks \
gnome-x11-gesture-daemon \
nautilus-admin \
nobara-gnome-layouts \
qt5ct

Install KDE:

sudo dnf groupinstall -y \
guest-desktop-agents \
kde-apps \
kde-desktop-environment \
kde-media \
standard --exclude=ffmpeg,ffmpeg-libs

Cleanup KDE bloat:

Cleanup leftover GNOME packages:

sudo dnf remove \
gnome-shell-extension-arc-menu \
gnome-shell-extension-clipboard-history \
gnome-shell-extension-custom-accent-colors \
gnome-shell-extension-gesture-improvements \
gnome-shell-extension-quick-settings-tweaker \

gnome-shell-nobara-theming \
gnome-extension-manager \
gnome-x11-gesture-daemon \
nobara-gnome-layouts \
gnome-shell-ext* \
gdm \
gnome-shell

Re-install some core KDE packages (they may have been removed during de-bloat):

sudo dnf install -y \
ark \
fedora-workstation-repositories \
ffmpegthumbs \
kate \
kde-l10n \
kde-runtime \
kf5-kimageformats \
okular \
sddm-kcm \
supergfxctl-plasmoid \
mpv \
plasma-lookandfeel-nobara \
libreoffice \
steam

You may also need to reinstall nextcloud client if you use it:

sudo dnf install -y nextcloud-client

Apply Nobara KDE theme:

cp -R /etc/xdg/* ~/.config/
lookandfeeltool -a org.nobaraproject.desktop
gsettings set org.gnome.desktop.interface gtk-theme Nobara

Reboot:

sudo systemctl reboot

And now you’re done!
