​
PAM

var auth = otter_desktop.PamAuth.init("otter-lock");
const result = try auth.authenticate(password);
PamSession wraps full session open/close for otter-greeter. Build with -Denable_pam=true for lock and greeter packages.

​
Session catalog

session_catalog scans Wayland .desktop session files and maps DesktopNames to XDG session environment variables. session_launcher builds user/session env without inventing logind-owned variables.

​
Accounts and seats

  • accounts_service: user list with passwd fallback
  • logind_seats: seat records and watch hooks for greeter UI

​
Power actions

power_actions routes shutdown, reboot, and suspend through logind policy checks.

​
Greeter integration

otter-greeter composes these modules with otter-ui Surface Description. Lock screen (otter-lock) uses PamAuth only; greeter uses full PamSession plus session picker.

​
Polkit and fprintd

PolkitAgent registers the desktop auth agent. Fprintd adds fingerprint auth for lock and polkit dialogs when hardware is there.
