External Monitor

[Henriette Holm]

Hi.
I have a laptop with a ATI Radeon 9700. When I connect an external
monitor to the computer and boot it, everything works fine until Gnome
starts. Then the picture on the external monitor disappears and it
shows a "no signal" error.
My xorg.conf looks like this:

Section "Files"
	FontPath	"unix/:7100"			# local font server
	# if the local font server has problems, we can fall back on these
	FontPath	"/usr/lib/X11/fonts/misc"
