xubuntu lightdm unity-greeter bad looking theme

Question

I'm using xubuntu 12.10 and wanted to use the unity-greeter for the login screen (lightdm). The thing is that I installed the package unity-greeter (and gnome-settings-daemon), changed to unity-greeter in the lightdm.conf file but the login screen turned out something like this http://i.imgur.com/lSsnng3.png and this http://i.imgur.com/QTdu0Xo.png (please ignore the vertical panel, I used the --test-mode to take the screenshots). As you can see the theme doesn't look as it should, there are those "old" icons used and when I click to select the environment it can be seen that the windows look like beeing an old debian theme.

What can I do to make it look "normal" ?

Answer 1

Obviously, you are missing some packages.

This should be ubuntu-artwork and if that fails, ubuntu-desktop will throw in the remainder.

However, if you are disappointed by the xubuntu greeter, having a look at the elementary project might help.
