A quick post on how to get Ubuntu 14.04 graphics working with Virtualbox 3.6 with Ubuntu 12.04

This post is going to be short and to the point.

The title is a mouthful I know, but it does describe the problem.

Like all users of Virtualization I like the ability to look at the future and the past of operating systems, but with this combination it was proving problematic.

Basically the screen resolution was dreadful after installing the Virtualbox tools on the Ubuntu 14.04 guest, and something needed to be done.

I trawled the web and found the following commands that should be run in the guest 14.04 virtual machine, and you then get graphic resolutions you can work with for testing.

Here they are.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install linux-headers-$(uname -r)

sudo apt-get install dkms build-essential

Then mount the install CD image for the Virtualbox tools and install them.

cd /media/nick/VBOXADDITIONS_4.3.6_91406/
sudo ./VBoxLinuxAdditions.run

sudo apt-get install virtualbox-guest-x11

Then, once this is done you will have decent screen resolutions.

Hope this saves you some time and effort.
