Well, not quite - this output shows that X knows the measurements of your LVDS display, ie, your laptop's built-in panel. The external screen are not detected - that confirms this is not a problem in E. Since X doesn't detect a display connected to the other outputs, E is disabling them. I bet flwm doesn't have any knowledge of xrandr, and just runs on any X display it finds. I don't know why the connection would be misreported - probably a bug in the video driver. Ross
