Because it requires Compiz, Emerald doesn’t work in GNOME Shell, but it should work with Unity (3D), GNOME Classic with Compiz or Xfce with Compiz for instance.

Install Emerald Window Decorator in Ubuntu 13.04, 12.10 or 12.04
Also, please keep in mind that Emerald Window Decorator is no longer developed / supported and while I’ve tested it for about two days in Ubuntu 13.04 (as well as some brief testing under Ubuntu 12.10 and 12.04 in VirtualBox) and I didn’t encounter any issues, there might be bugs or it may not work at all.
That said, let’s proceed with the Emerald installation:
sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install emerald
sudo apt-get install compizconfig-settings-manager
Reverting the changes
sudo apt-get remove emerald
