Ubuntu – Ubuntu as guest OS (with Vista host) stuck at 800×600 resolution

Higher screen resolution in VirtualBox?

I believe I've successfully got Ubuntu 10.04 installed as the guest OS with Vista as host on my laptop. But I have been unable to get it to use the entire monitor. In Ubuntu and using the System-> Monitor Preferences, I have one monitor "Unknown" with a resolution of 800×600 and haven't found out how to change it to use the full 1920×1200 of my laptop.

I'm using Oracle's VM VirtualBox.

I am new to ubuntu (and *nix in general), so I could be missing something easy.

You need to install Guest Additions if you are using VirtualBox or a similar feature if it's some other virtualization software.
