Yes, as noted in the bug report. The trigger is user 1 logging out back to gdm while user 2 still has a session going. When user 2 logs in through gdm back to their running session.
This has happened reliably for me, 100% of the time so far after a small number of attempts. My auth.log corresponds to Mark's findings as follows. Also, using Ctrl+Alt+F-keys to get back to the gdm prompt stops the repeat. A message is briefly present indicating exactly what the auth.log is reporting, ie that the username or password is invalid. Perhaps this is a simple as an enter key being effectively held down in the X session gdm is using? auth.log output from around the time the login attention sound starts: May 16 14:16:23 lillian dbus-daemon: Rejected send message, 1 matched rules; type="method_call", sender=":1.105" (uid=1002 pid=10668 comm="/usr/lib/indicator-applet/indicator-applet --oaf-a") interface="org.freedesktop.DBus.Properties" member="Get" error name="(unset)" requested_reply=0 destination=":1.124" (uid=0 pid=2961 comm="/usr/sbin/gdm ")) May 16 14:16:31 lillian dbus-daemon: Rejected send message, 1 matched rules; type="method_call", sender=":1.105" (uid=1002 pid=10668 comm="/usr/lib/indicator-applet/indicator-applet --oaf-a") interface="org.freedesktop.DBus.Properties" member="Get" error name="(unset)" requested_reply=0 destination=":1.125" (uid=0 pid=2961 comm="/usr/sbin/gdm ")) May 16 14:16:32 lillian gdm[2961]: pam_unix(gdm:auth): check pass; user unknown May 16 14:16:32 lillian gdm[2961]: pam_unix(gdm:auth): authentication failure; logname= uid=0 euid=0 tty=:0 ruser= rhost= May 16 14:16:34 lillian gdm[2961]: pam_unix(gdm:auth): check pass; user unknown May 16 14:16:34 lillian gdm[2961]: pam_unix(gdm:auth): authentication failure; logname= uid=0 euid=0 tty=:0 ruser= rhost= May 16 14:16:36 lillian gdm[2961]: pam_unix(gdm:auth): check pass; user unknown May 16 14:16:36 lillian gdm[2961]: pam_unix(gdm:auth): authentication failure; logname= uid=0 euid=0 tty=:0 ruser= rhost= May 16 14:16:38 lillian gdm[2961]: pam_unix(gdm:auth): check pass; user unknown May 16 14:16:38 lillian gdm[2961]: pam_unix(gdm:auth): authentication failure; logname= uid=0 euid=0 tty=:0 ruser= rhost= May 16 14:16:40 lillian gdm[2961]: pam_unix(gdm:auth): check pass; user unknown May 16 14:16:40 lillian gdm[2961]: pam_unix(gdm:auth): authentication failure; logname= uid=0 euid=0 tty=:0 ruser= rhost= 2009/5/14 Sebastien Bacher <seb...@ubuntu.com>: > do you have a reliable way to trigger the issue? > > -- > Login attention sound on continuous repeat after user switch > https://bugs.launchpad.net/bugs/373961 > You received this bug notification because you are a direct subscriber > of the bug. > -- Login attention sound on continuous repeat after user switch https://bugs.launchpad.net/bugs/373961 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
