Same trouble here on a kubuntu gutsy gibbon, the "Administrator Mode" seems broken.
I ran systemsettings from konsole, and click on "Disks and Filesystems", konsole says: 8<-----------8<---------8<----------8<----------8<----------8<----------8< $ systemsettings adding Disk & Filesystems /usr/share/applications/kde/mountconfig.desktop Pythonize constructor -- pid = 7311 Python interpreter initialized! Pythonize constructor -- pid = 7311 8<-----------8<---------8<----------8<----------8<----------8<----------8< When I click the "Administrator Mode" button, the following line is added to konsole: 8<-----------8<---------8<----------8<----------8<----------8<----------8< passprompt 8<-----------8<---------8<----------8<----------8<----------8<----------8< Sometimes (sorry I cannot say in which circumstances) a window titled "Kdesudo" appears saying: "/usr/bin/kcmshell System/mountconfig --embed-proxy 48237627 --lang fr needs administrative privileges. Please enter your password for verification" So I type my password And in the konsole window, one can read: 8<-----------8<---------8<----------8<----------8<----------8<----------8< Xlib: connection to ":0.0" refused by server Xlib: Invalid MIT-MAGIC-COOKIE-1 key kcmshell: cannot connect to X server :0 8<-----------8<---------8<----------8<----------8<----------8<----------8< Hope this will help to solve this annoying bug. The workaround is to launch systemsettings from the konsole with the command 'sudo systemsettings' -- Give me a woman who loves beer and I will conquer the world. -+- Kaiser Welhelm -+- -- Administrator Mode does not work https://bugs.launchpad.net/bugs/176518 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
