Uninstalling

Uninstalling

AUR

yay -R wallpaper-engine-kde-plugin-new-fork

RPM

# Standard Fedora
sudo dnf remove wallpaper-engine-kde-plugin-qt6

# rpm-ostree (Bazzite, Silverblue, Kinoite)
rpm-ostree uninstall wallpaper-engine-kde-plugin-qt6
systemctl reboot

From source

1. Remove the files listed in build/install_manifest.txt (cmake generates this when you ran cmake --install):

   cd wallpaper-engine-kde-plugin
   sudo xargs rm -v < build/install_manifest.txt

2. Unregister the Plasma wallpaper package:

   kpackagetool6 -t Plasma/Wallpaper -r com.github.captsilver.wallpaperEngineKde

3. Restart Plasma:

   systemctl --user restart plasma-plasmashell.service

Cleaning per-user config

If you also want to clear per-wallpaper settings (the JSON files the plugin writes for each wallpaper's properties):

rm -rf ~/.local/share/plasma/wallpapers/com.github.captsilver.wallpaperEngineKde/
# and any plugin-specific config in:
ls ~/.config | grep -i wallpaper
