I had the same problem. I run 8.04 upgraded from 7.10 on a laptop with an attached screen. Two instances of gnome (no xinerama).
After checking that I had my account added to /etc/group to admin and polkitusers groups and reconfiguring the package i discovered that the button actually did work, however only on the laptop-screen. If I start an administrative tool on my laptop screen everything works fine, but if i try to do the same on the external screen i get an "unexpected error". This really seems like a bug in whatever voodoo that handles policykit. Like it can't bind to the correct window manager or something. -- Unlock button throws an error, doesn't authenticate https://bugs.launchpad.net/bugs/187335 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
