After installing Gnome 3 on my Ubuntu 13.04 (Unity) the "notification dialog theme" (screenshot below) changed. I'd like to know if is possible to return to the Unity default notification dialog theme without needing to uninstall Gnome 3.
Thanks in advance.
sudo apt-get purge xfce4 xfce4-notifyd xfce4-session xfce4-settings xfce4-volumed
and then logout and login again. Maybe GNOME also leaves some packages around even after removing the package?
