Steps1: Option1: Installing gnome-art,an application for managing the splash screens of the GNOME desktop.Go to Applications->Ubuntu Software Center,search and install “art manager”(without quotes).Once installation finish,launch this from System->Preferences->Art Manager,or type “gnome-art”(without quotes) in terminal.

So We installed Gnome-Art NextGen instead.download deb package from this pageUse this command to install(open terminal from Applications/Accessories/Terminal to run command),or double click to install:
sudo dpkg -i name
and we installed i386 deb package in my amd64 machine:

Now,launch Gnome-Art NextGen by typing “gnomeartng”(without quotes) in terminal.

Step2:Install window border theme.

If installed gnome-art,navigate to Art Manager -> Art-> Desktop Themes -> Window Border,and choose theme “Metativo”(you can choose one as you like.)

gconf-editor
navigate to desktop->gnome->session->required_component.In right box,double click “panel” and change its value to “cairo-dock”
