So, I installed gnome-settings-daemon and ran it, and the problem persisted. Furthermore, I have another i386 Natty system that runs a full Ubuntu desktop. On that other system, users-admin works without problems, and gnome-settings-daemon is installed and runs all the time. So I tried killing gnome-settings-daemon on that other system, and users-admin continued to work without problems.
But installing and running gnome-settings-daemon did enable me to complete your instructions. I ran: export PID=`pidof gnome-settings-daemon` pkcheck --action-id org.freedesktop.systemtoolsbackends.set --allow-user-interaction --process $PID The output was "Not authorized." -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/685596 Title: users-admin edit dialogs don't show up -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
