Security
This project intentionally keeps almost all functionality unprivileged.
Privileged operation
Only chvt requires root privileges. The recommended sudoers rule is limited to:
/usr/bin/chvt
or, when the machine uses fixed VTs, to explicit arguments such as:
/usr/bin/chvt 1
/usr/bin/chvt 2
Do not configure unrestricted passwordless sudo for the user or for the recovery scripts.
Non-interactive sudo
The recovery script always invokes sudo with -n:
sudo -n /usr/bin/chvt ...
This prevents the systemd user service from hanging on a password prompt.
Boot safety
DRM hotplug events can occur during boot. The watcher therefore verifies that the current user has an active Wayland session with a valid VT before any recovery or VT switch is attempted.
Reporting security issues
If this repository is published publicly, report security-sensitive findings privately through the repository owner's preferred security contact rather than opening a public issue containing exploitable details.
