Ok, pam-ck-connector is creating an additional CK session now, which I don't think it is meant to be doing. I turned on debug and logged in again, and this is what I see:
Sep 15 23:18:33 farnsworth lightdm: pam_ck_connector(lightdm:session): using 1000 as uid Sep 15 23:18:33 farnsworth lightdm: pam_ck_connector(lightdm:session): open session result: 1 Sep 15 23:18:33 farnsworth lightdm: pam_ck_connector(lightdm:session): registered uid=1000 on tty='/dev/tty7' with ConsoleKit This shouldn't happen, because we use the "nox11" option for pam-ck- connector. This has started because of this commit: http://bazaar.launchpad.net /~lightdm-team/lightdm/trunk/revision/1144 The problem seems to be that pam-ck-connector expects PAM_TTY to contain the X display, rather than the tty device path. It then bails out if it interprets this item as an X display: if (strchr (display_device, ':') != NULL) { if (opt_nox11) { ck_pam_syslog (pamh, LOG_WARNING, "nox11 mode, ignoring PAM_TTY %s", display_device); goto out; } x11_display = display_device; display_device = ""; Because PAM_TTY is /dev/tty7 for me, it goes ahead and creates a CK session (FTR, before the lightdm update, pam-ck-connector bailed out with "pam_ck_connector(lightdm:session): cannot determine display-device") -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/851055 Title: [Oneiric] 'Not Authorized' error given when mounting device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/851055/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
