cinnamon-settings is broken by gnome 3.4 changes (dbus).

Here's the error

org.gnome.SettingsDaemon.DateTimeMechanism no longer exists in gnome 3.4

I am having the same problem. I need to change me theme settings, and can not.

[leigh123linux]

Try this patch (it strips the time settings as it's obsolete).

It's still broken.

There are two mostly equivalent dbus APIs for setting the date and time:

• org.gnome.SettingsDaemon.DateTimeMechanism: implemented by gnome-settings-daemon, removed upstream in version 3.3.5, and added back via a patch in Debian. But other distros that follow Gnome upstream more closely no longer support this interface.
• org.freedesktop.timedate1: implemented by systemd's timedated, and by openrc-settingsd in Gentoo. This is the "modern replacement" for the g-s-d DateTimeMechanism API, and is preferred by Gnome upstream developers.

IMHO, the bug should be fixed by patching cinnamon-settings to support both of these APIs, and switch at runtime to whichever one is currently available. The following patches allow it to do so:

• Add a wrapper to switch between timedated and g-s-d's DateTimeMechanism #1109 for the stable branch;
• Add a wrapper to switch between timedated and g-s-d's DateTimeMechanism #1110 for master branch.
