Gnome dektop on Ubuntu 14.04


How can I install the Gnome Desktop on the Ubuntu 14.04 ?

I have Installed Ubuntu 14.04 successfully and executed following commands:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install ubuntu-gnome-Desktop
sudo reboot

At boot the pinquin is shown, but after the System in up my display stays black, so no Desktop visible!!

How can fix this?

I have a Beaglebone black rev.C with the 4D System 7" Display cape.

With the ängstrom Image Gnome and the Display are working.

I believe there were previous posts a while back about disabling the screen saver …
