How to open gui or desktop on ubuntu?

I installed bitnami lampstack for vmware. When I run it, the vmware starts in ubuntu shell. How can I open the gui desktop of ubuntu from there?

The Virtual Appliances do not have the graphical desktop installed because it is not necessary to run the web application. You can install the Desktop using the follwing commands:

$ sudo apt-get update
$ sudo apt-get install ubuntu-desktop

I hope it helps.
