Have you tried with this as well?

I suppose

	Option	"MonitorLayout" "LVDS,CRT"

doesn't work better?

BTW, it's better not to specify this unless the driver misdetects the
amount of video RAM, which is unlikely for the radeon driver. That's not
the problem though.

This is an important part of the problem - the DDC code still doesn't
work with the M6, so the driver has no way to determine the panel
parameters it needs to drive it correctly. The only chance I see for
this to change is if someone who is prepared to build XFree86 CVS gets
in touch with Hui Yu (provided he's willing to help with this).

BTW, you could override this with

	Option	"CloneHSync"	"30.0-100.0"
	Option	"CloneVRefresh"	"50.0-160.0"

Weird, the driver thinks it's driving the external output at 640x480@60
...


I suppose a 'real' multihead configuration doesn't work better?
