virtualboxwindows 7
I've installed win7 on virtualbox on ubuntu 12.04. However, the full screen mode isn't perfect. I have black parts on both sides of the screen. I tried changing the resolution but nothing fits.
Anyway to fix this?
By the way, my ubuntu is 64-bit (intel 4000 graphic card), and the my win7 is 32-bit. I'm not sure if this is the cause of the issue.
Virtual Box has the option to run in "scaled" mode. This means that any screen size will be enlarged or reduced by the same factor as the host windows size changes. The scaling also effects desktop elemets that may be rendered distorted then:
When Guest Additions are installed (see this answer), and only then, we are also able to fit the guest desktop to an altered host windows size. Desktop elements will then be rendered correctly to fit into the virtual desktop size.
Pressing the key commands switches the given feature on or off.
You may need to install the virtualbox expansion pack:
Also, I would make sure hardware virtualization is enabled:
SETTINGS > SYSTEM > ACCELERATION TAB > both checkboxes checked

You need to install the VirtualBox guest additions. Start Windows in your Virtualbox, and from the Virtualbox menu select "Devices -> Install guest additions"
Guest additions allow you a more seamless integration with the Linux desktop. Not only will you be able to have a better resolution and automatically adjust the resolution to the X window size, but in addition your mouse pointer will no longer be trapped by the Windows host, you will be able to share folders and more.
