After selecting which video adapter I have, an option is available to 'Test
X configuration' -- when clicked, the selected X server is started, and a
dialog box is displayed -- off the screen to the lower right corner. While
it can be accessed by scrolling to the lower right, it _should_ be centered
-- ie, the virtual resolution should be the same as the physical
resolution. This is before the resolution and color depth selection
dialog, which also has a 'Test X configuration' button.
