Environment: Lenovo T530 running Windows 7. Have installed Ubuntu 14.04 on a virtual machine using VM Virtual Box. Have installed all the updates from both Virtual Box and Ubuntu.

Problem: While in Ubuntu's desktop and other Ubuntu initiated programs, the window is reduced to about 3x4 inches showing in the middle of the rest of my regular Virtual Box window. I am seeing only the upper right hand of the screen output of what I would normally see. Please help.

I've seen How do I install Guest Additions in a VirtualBox VM?

But, none of these answers works in 14.04.
