Same problem since upgrading to 10.10. I can't seem to find any meaningful error message anywhere (except the one mentioned here).
This is what /var/log/gdm/:0-slave.log contains: gdm-session-worker[3950]: GLib-GObject-CRITICAL: g_value_get_boolean: assertion `G_VALUE_HOLDS_BOOLEAN (value)' failed gdm-session-worker[3950]: pam_succeed_if(gdm:auth): requirement "user ingroup nopasswdlogin" not met by user "philippe" gdm-session-worker[3950]: pam_unix(gdm:session): session opened for user philippe by (uid=0) gdm-session-worker[3950]: pam_ck_connector(gdm:session): nox11 mode, ignoring PAM_TTY :0 gdm-session-worker[3950]: pam_unix(gdm:session): session closed for user philippe Even tried strace on the gdm-session-worker process, but got nowhere. I've upgraded Ubuntu on this machine since 7.04, never had such a mysterious issue before. I've seen this symptom reported several times and with different workarounds: * some have faulty .files in their home dir, fixing these resolves the issue * some have issues related to the nvidia driver (bug 516520) * sometimes, the problem is intermittent: making several attempts to login works at some point (timing issue?). * some have reported that a different resolution in GDM and Gnome causes this: setting both to the same fixes the issue (http://ubuntuforums.org/showthread.php?t=1338879) Any help appreciated! -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm in ubuntu. https://bugs.launchpad.net/bugs/663135 Title: gdm broken after update to 10.10 - instant session end - signal 15 - after login -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
