We have a computer with an nVidia 7100GS video card and a Dell 1908FP monitor. The video card works fine after downloading and installing the driver from the nVidia web site. But the display only gives the choice of “800×600” or “640×480” resolutions. To get “1280×1024” resolution, edit /etc/X11/xorg.conf. Here are the relevant sections (info added is in bold):
