As Chris Coulson wrote, the problem can be solved by using System -> Administration -> Authorizations. Of course, for those of us that don't have access to that one either (due to the same problem, I assume), the sollution is to start it with
gksudo polkit-gnome-authorization This lets you give explicit authorizations for specific users for specific tasks. For example, freedesktop/systemtoolsbackends/"Manage system configurations" Click the 'Grant' button and take it from there. This solved my NX problems. At least so far. -- 'Unlock' button is grayed out in system tools https://bugs.launchpad.net/bugs/287932 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
