When running the Display settings (gnome-control-center display) under Gnome 3.6 on Ubuntu 13.04 I'm unable to apply any settings (even if nothing changes). The error I get is:
Failed to apply configuration: %s
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SettingsDaemon was not provided by any .service files.
Background:
I've tried to use the newer 3.8 release from the PPA's but that didn't help, I've now reverted to the 3.6 release. I've also tried removing all my gnome related config files, but that didn't make a difference.
The error message:
