I now have good log output which I've attached to https://bugzilla.redhat.com/show_bug.cgi?id=472248 Meanwhile, my logwatch report has come in. Could these entries have any bearing? kdm: :0: PAM adding faulty module: /lib/security/pam_gnome_keyring.so: 6 Time(s) kdm: :0: PAM unable to dlopen(/lib/security/pam_gnome_keyring.so): /lib/security/pam_gnome_keyring.so: cannot open shared object file: No such file or directory: 6 Time(s) Certainly gnome-keyring is used by NetworkManager. If it's likely to be involved, I'll add this output to the bug report. Anne
