I can confirm this bug too with ATI RV350 using ati driver. This bug occurred when I was struggling with Compiz and desktop effects. I also could type Ctrl-Alt+backspace and see some failing notes scrolling in the console but couldn't register the significance of them. I have the impression that xorg is looking for a second monitor or a TV attached to the video driver.
