This method creates system-wide configuration which is persistent across reboots. Using the Pythagorean theorem on a 13.3" diagonal length screen with a 1280x800 native resolution (or 16:10 aspect ratio): This will give the pixel diagonal length, and with this value you can discover the physical horizontal and vertical lengths (and convert them to millimeters): For RandR compliant drivers (for example the open source ATI driver), you can set it by: To make it permanent, see Autostarting#On Xorg startup. producing the image seen on screen. -- A. de Saint-Exupery.
