Hm, indeed, sorry. Next step would be to run the authentication agent manualy after killing the one that is running, and see if it changes something. If it doesn't, have a look at the messages it prints to the console, and also to the messages printed by polkitd, which (IIRC) should also say it detected the agent.
But please try all this stuff with a /local/ GDM session. If it works, we'll check VNC, but mixing two potential error sources is not a good idea. -- users-admin cannot get authorized from policy kit in VNC session https://bugs.launchpad.net/bugs/668901 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-system-tools in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
