Eugene, the GDM source also says you may need to create user 'gdm- greeter-2'...
https://gitlab.gnome.org/GNOME/gdm/-/blob/main/daemon/gdm-dynamic-user- store.c?ref_type=heads#L809 You should ignore all the threads blocked in poll() because that's the normal state of most threads. Fred, thanks for confirming the fix. This seems like a case of GDM making unreasonable assumptions, failing to support systems whose /etc/nsswitch.conf has not been updated in several years. Also failing to support machines where the user might have customised /etc/nsswitch.conf. All are valid configurations that should not prevent you from having a login screen. The regression was only introduced recently in: https://gitlab.gnome.org/GNOME/gdm/-/commit/beb16b4746856ebd5b3fd9693775757a06a7bb48 ** Changed in: gdm3 (Ubuntu) Status: Confirmed => Triaged ** No longer affects: apparmor (Ubuntu) ** No longer affects: gnome-session (Ubuntu) ** No longer affects: pam (Ubuntu) ** Summary changed: - Gdm3 doesn't start [unix_chkpwd: could not obtain user info (gdm-greeter)] + Gdm3 doesn't start [unix_chkpwd: could not obtain user info (gdm-greeter)] on systems installed before 2024 ** Summary changed: - Gdm3 doesn't start [unix_chkpwd: could not obtain user info (gdm-greeter)] on systems installed before 2024 + 25.10's gdm3 doesn't start [unix_chkpwd: could not obtain user info (gdm-greeter)] on systems installed before 2024 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/2121017 Title: 25.10's gdm3 doesn't start [unix_chkpwd: could not obtain user info (gdm-greeter)] on systems installed before 2024 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/2121017/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
