Setting up Lock, Restart, and Shutdown Menu in Linux Mint

Run this in Terminal—no sudo needed:

</> Bash`

python3 /home/ben/Documents/Codex/2026-10-15/set/outputs/system-menu.py --install

It registers Super + Shift + L for a popup containing Lock, Suspend, Log out, Restart, and Shut down. Press Esc to dismiss it.

The installer checks for shortcut conflicts. I couldn’t install it directly because the sandbox error persists.
