I'm using Kubuntu Gutsy, fully updated, and have had this problem since upgrading from Feisty.
One interesting workaround, though it does require gksudo, is to simply do: gksudo kcontrol. This generated the following konsole output: $ gksudo kcontrol kbuildsycoca running... ing new authority file /root/.ICEauthority DCOP Cleaning up dead connections. kdecore (KProcess): WARNING: _attachPty() 12 QImage::smoothScale: Image is a null image QImage::smoothScale: Image is a null image QImage::smoothScale: Image is a null image $ The 'cleaning up dead connections' part looks interesting.... After doing this, the root-owned dcopserver was gone, but more importantly, future use of kcontrol from the normal menus just works - e.g. on the Login Manager tool within Kcontrol, the Administrator Mode works (doesn't prompt as the sudo is established I guess.) Not sure if I will need to re-do the gksudo invocation every time the sudo credentials run out, but since "gksudo kcontrol" could be put in the KDE menus it may be a better workaround than using Konsole. I would still really like to see a fix though. -- Administrator button fails to work in kde-settings and kcontrol https://bugs.launchpad.net/bugs/175909 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
