Subject: [PATCH] Set greeter_session instead of session when reconfiguring the
 display_server after a session startup failure

When using a Wayland desktop environment with auto-login enabled, if the account password has expired, the auto-login process fails due to password expiration. This results in a black screen with no functional login interface. I traced the issue to the switch_to_greeter_from_failed_session function and discovered that the display_server was still configured to use the original session type (session) during reinitialization. After modifying the session type to greeter_session, the problem was resolved. This fix ensures the display server correctly triggers the login manager (greeter) when handling authentication failures.
