I am running an Ubuntu 12.04 VirtualBox guest (with Guest Additions installed) within a Windows 7 host.
How can I set the resolution of the guest VB to match the physical machine's native resolution (1280 x 800)? IOW, is there a way to add 1280 x 800 to the available options?
The highest resolution available under the
System Settings > Displays that "fits" within the native one is 1024 x 768, which gives an aspect ratio of 4:3, whereas the native resolution gives an aspect ratio of 8:5 (better known as 16:10, for some reason). Choosing this resolution means that a considerable portion of the screen is left unused (which is a big deal when working with a tiny screen to begin with). All the other resolution choices available through
System Settings > Displays give a 4:3 aspect ratio. (E.g. there's also a 1280 x 960 option, which does use the full width of the screen, but results in the loss of the bottom 160-pixel-high strip of the image.)
