I just installed openSUSE and can't seem to get my monitor to display at 1920x1200. I have my monitor set to LCD>>1920x1200@60HZ, but my maximum selectable resolution is 1600x1200. This is on an Acer P241W and openSUSE is version 11.1 running through Sun VirtualBox. Any help would be appreciated (I'm a linux newcommer).
