Force Quit — KDE Plasma 6 applet

A port of the Cinnamon Force Quit spice (force-quit@cinnamon.org) to a Plasma 6 panel applet.

Source: https://github.com/WACOMalt/force-quit

Click the panel icon, then click any window — it is killed immediately.

Why not xkill?

The Cinnamon original shells out to xkill, an X11 utility. Under a Wayland session xkill can only reach XWayland clients, so it silently fails on Wayland-native windows (and it isn't installed by default on Fedora/Nobara).

This applet instead calls KWin's own org.kde.KWin.killWindow() over D-Bus. That's the same code path as the built-in Ctrl+Alt+Esc shortcut, and it works for both Wayland and X11 windows.

Install

kpackagetool6 --type Plasma/Applet --install package

To update after editing, use --upgrade instead of --install; to remove:

kpackagetool6 --type Plasma/Applet --remove bsums.xyz.forcequit

Then right-click the panel → Add or Manage Widgets… → search "Force Quit" → drag it onto the panel.

Layout

• package/metadata.json — applet id, name, icon, Plasma API version
• package/contents/ui/main.qml — the whole applet
• make-plasmoid.sh — builds dist/force-quit-<version>.plasmoid for the KDE Store
• PUBLISHING.md — KDE Store listing text and release steps

Publishing

See PUBLISHING.md. Build the store package with:

./make-plasmoid.sh

Notes

• No dependency beyond qdbus (Plasma already pulls it in); the applet probes for qdbus6 / qdbus-qt6 / qdbus so it works across distro naming.
• Tested on Plasma 6.7.4, Wayland, Nobara/Fedora 44.
