Unfortunately, no. No change in behaviour. > It might be interesting to try starting the machine with the laptop > screen closed as well. I actually did this in my tests. What's really strange is that it seems to follow no obvious pattern in behaviour. One time I boot the machine with both external screens switched on, I can see the kernel messages scrolling its way down duplicated on both screens. Another time, the screen connected to the DVI port remains dark. This doesn't directly allow predictions whether X starts with both screens enabled, or not. It seems to behave independently.
