Comment 6 for bug 1219486

Running gnome-shell 3.8 on gnome-settings-daemon 3.6 is likely to be very buggy and unstable. Although admittedly it hasn’t had a huge amount of testing since the assumption was that we would get g-s-d 3.8 into saucy.

For the 3.8 cycle many features were moved out of gnome-settings-daemon and into other components such as mutter and gnome-shell. Most of these however require code changes in g-s-d to use the new components. Other than this there were not really many new features added to g-s-d and it is largely just a big bug fix release.

- OSD Popups are now drawn by gnome-shell so that they match the shell UI.
- Keygrabber was moved into gnome-shell, since there were lots of issues with media_keys keybindings not working in certain parts of gnome-shell
- Background plugin was moved into mutter
- Screenshots are handled by gnome-shell.
- Power support is pretty much broken when using g-s-d 3.6

All of these were moved to overcome technical limitations making it hard or impossible to fix key bugs. In most cases by sticking with 3.6 we do not get to take advantage of these new components and we are left using the old unmaintained and buggy implementations.

In addition there are lots of bug fixes for things like power plugin, notifications etc.
