Change Screen Resolution for Ubuntu in VirtualBox

Re: VirtualBox - How can I Increase Screen Resolution??
There's a great new simple solution to the screen size problem since the release of VirtualBox version 1.6.2.
Here is a solution for changing the screen resolution of Ubuntu running in VirtualBox:

It's a new VBoxManage command, explained in the Help Contents/ User Manual at section 9.12 under the heading "Configuring the maximum resolution of guests when using the graphical frontend".

As the default screen resolution option was unsatisfactory for me, I found by trial and error that the perfect resolution for a Guest on my Host's desktop (with a 19 inch LCD) is 1272 x 920. So in my HOST system, I shut down VirtualBox, then opened a terminal and typed:

VBoxManage setextradata global GUI/MaxGuestResolution 1272,920

This worked perfectly. Now when I run any guest machine in Virtualbox, the guest immediately opens to my desired screen size (1272x920) and it works consistently time after time. You can set any screen size you want this way. Absolutely no adjustments are required inside the guest machine's settings.
