The screen on my widescreen laptop is cracked. Until I repair it, I am using an external monitor. an lcd samsung syncmaster. But, the external LCD is not widescreen. the resolutions that system-config-display thinks are supported are all widescreen. I have no idea what's going on. I have tried --reconfig and finding my monitor in the list. But even when using a 'square' resolution, parts of it aren't viewable. 'off the side' of the monitor.
