This is a POC (proof of concept/piece of crap).
https://build.opensuse.org/package/show/home:tduck:filotimolinux/filotimo-atychia
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.
Requires a system user atychia (UID below 1000, and no home dir) which is in the atychia and video group.
You can make this with sudo useradd -r atychia && sudo usermod -a -G video atychia.
Requires an up to date version of KDE Frameworks 6, Qt 6, systemd, logind, and Polkit.
Also 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
