Fix a completely Blank (Black) Terminal - Ubuntu

When i try to open Terminal in Ubuntu it shows completely blank screen. I cant find any cursor or prompt.

After trying may things finally i got one solution.

Using Ctrl + Alt + F5
It will take to text console input.

$ apt-get install ubuntu-desktop

By using this command installed Ubuntu desktop. It resolved problem and now its working fine.

The same thing can be done for desktop resolution problem
