I've come accross the same bug with freenx. I guess somehow gtk or gnome initialization fails. E.g. time-admin gives the following error message when started from a freenx desktop within a shell:
** (time-admin:6522): CRITICAL **: Unable to lookup session information for process '6522' The error does not show up when time-admin ist run from a local gnome desktop. The behaviour is quite annoying as most of server administration comes remotely. -- 'Unlock' button in admin utilities greyed out https://bugs.launchpad.net/bugs/231246 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
