Virtualizing environments these days is a breeze. The simplest way of doing so is using Oracle Virtualbox . One thing I’ve noticed installing Ubuntu 12.04 was the fact that I was unable to select 800×600 or 1024×768 in screen resolution.
It turns out that you are obligated installing the virtualbox guest additions. Fire up your terminal and enter:
$ sudo apt-get install virtualbox-ose-guest-utils<br />$ sudo apt-get install virtualbox-ose-guest-x11<br />$ sudo apt-get install virtualbox-ose-guest-dkms
Now you should be able to select other screen resolutions more accustomed to your screen.
