Hello

I'm looking for information about what these two logs mean.
I checked it in tail -100 /var/svc/log/application-graphical-login-gdm.log.

<5>Gdm: Freeing conversation 'gdm-password' with active job
<5>accountsservice: ActUserManager: user (null) has no username (uid: -1)

Where can I find documentation about this information?
If anyone knows, please let me know.

Thank you
Best Regards

ChatGPT 4o Suggests:

You're seeing log messages related to GNOME Display Manager (GDM) and accountsservice, which handles user session and account data.

Here's a quick breakdown of each log entry:

1.

<5>Gdm: Freeing conversation 'gdm-password' with active job

  • This is from GDM.
  • It means GDM is cleaning up an authentication session (likely PAM-based) that wasn't completed—possibly a cancelled login or session timeout.
  • "with active job" hints the session was still processing something when it was freed.

:magnifying_glass_tilted_left: Source: GDM logs this internally; you can find references to this in GDM source or debug output with G_MESSAGES_DEBUG=all.

2.

<5>accountsservice: ActUserManager: user (null) has no username (uid: -1)

  • This comes from accountsservice.
  • It's indicating an internal failure to map a user ID (uid: -1) to a valid username.
  • Could be triggered by a system call like getpwuid(-1) failing.

:magnifying_glass_tilted_left: Source: accountsservice logs are part of /usr/libexec/accounts-daemon. Code is here: accountsservice GitHub mirror. Logs like this are triggered when invalid or incomplete user info is processed.

Where to find documentation:

  1. GDM logs/messages:

  2. accountsservice:

  3. System logs:

    • Use journalctl -u gdm or journalctl -xe for broader context.
    • Use strace -f -p $(pidof gdm) for live inspection (if needed).

Let me know if you'd like help matching these logs to a user login failure or another session-related issue.
