As you saw earlier about RandR, this doesn't mean it's actually enabled
but merely that it would be possible.

I think there were incompatible changes to RandR between XFree86 4.2 and
4.3, you may have to upgrade xbase-clients to the version in

Direct rendering isn't supported yet with Xinerama-less dualhead either.

The lid isn't supposed to have any effect, it needs to be connected and
preferably powered up when the X server starts up. If DDC detection
doesn't work for the external monitor, you can try something like

	Option	"MonitorLayout"	"LVDS,CRT"

(if it's connected via an analog VGA connector) or

	Option	"MonitorLayout"	"LVDS,TMDS"

(if it's connected digitally, though there may still be driver problems
preventing it from working in that case)
