I have experienced identical behaviour. A complete re-install of Kubuntu Gutsy has not helped.
I have filed Bug #175909 in kde-systemsettings because this bug is marked closed. The messages on console when the Administrator Mode button is clicked are: ******************************** --------------------------------- It looks like dcopserver is already running. If you are sure that it is not already running, remove /root/.DCOPserver_kaveri__0 and start dcopserver again. --------------------------------- WARNING: Waiting for already running klauncher to exit.
