Windows – How to get VirtualBox to play nicely with dual monitors

Ubuntuvirtualboxwindows-vista

I use VirtualBox to run a Ubuntu x64 guest under a Vista x64 host with a 19" and 15" monitor.

I enable seamless mode in VirtualBox, but the windows don't actually move anywhere other than the desktop of the Ubuntu guest.

I'd also like fullscreen mode to display across both monitors.

How can I do this?

According to this forum post and looking through the VirtualBox release notes this is only available to Windows Guests. I know the latest 3 release introduced huge improvements on the 3D rendering side and with OpenGL. I would assume this would be available in the near future.

And according to the 4.0 release notes, the feature is available!

Guest Additions: support for multiple virtual screens in Linux and Solaris guests using X.Org server 1.3 and later
