A utility akin to Ctrl-Alt-Delete on Windows that allows a user to recover from a broken session, rather than being forced to a TTY.
This automatically registers a shortcut with KDE, and is designed for use with KDE. Registers Meta+Ctrl+Alt+Del by default.
A shortcut is also registered to relaunch Plasmashell - Meta+Ctrl+Shift+B.
Attempts to look a bit like the Plymouth boot screen - you'll find that it takes the watermark from the spinner theme, and has a black background for consistency.
Requires an up to date version of KDE Frameworks 6, Qt 6, systemd, logind, and Polkit.
Requires cage, the Wayland kiosk compositor, to be installed.
You can build and install this with the following:
mkdir -p build && cd build
cmake .. -G "Kate - Ninja" -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
sudo ninja-build -C . install
