Actually it's not a duplicate, it's almost the opposite. #34795 complains that autologin happens on "switch user", and tries to log in as the same user already logged in before, which is clearly not helpful.
That was apparently "fixed" (enough to close #34795) by completely disabling auto login after the first login. I don't think that's the right solution. There are systems where people log in and out frequently: * internet cafes * multihead systems like this bug and [https://bugzilla.gnome.org/show_bug.cgi?id=336174#c44] * many use cases for "switch user", e.g. testing locked-down accounts, shared home computer, media centre computer The "best" solution imho would be to check whether the autologin user is already logged in, and disable autologin in that case. A hack would be to disable autologin on "switch user". ** Bug watch added: GNOME Bug Tracker #336174 https://bugzilla.gnome.org/show_bug.cgi?id=336174 ** This bug is no longer a duplicate of bug 34795 "authentication failed" on "switch user" with timed login -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/56035 Title: Autologin dont work on the second Xserver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/56035/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
