Do you have any idea?

I am using a kernel 2.6.12 with xfree server.

My computer is the following:
processor       : 0
cpu             : 7447A, altivec supported
clock           : 1666MHz
revision        : 0.5 (pvr 8003 0105)
bogomips        : 1658.88
machine         : PowerBook5,6
motherboard     : PowerBook5,6 MacRISC3 Power Macintosh
detected as     : 287 (PowerBook G4 15")
pmac flags      : 0000001b
L2 cache        : 512K unified
memory          : 2048MB
pmac-generation : NewWorld
    

On my Powerbook G4 15" (PowerBook5,2) I was able to mirror my internal
display on an external screen. Therefore I had to install the Debian
Package xserver-xorg instead of using the xfree86 server. Afterwards I
had to make the following modifications of the file /etx/X11/xorg.conf:

Section "Device"
	Identifier	"ATI Radeon 9600"
	Driver		"radeon"
	Screen		0
EndSection

Section "Device"
	Identifier	"ATI Radeon 9600 Card1"
	Driver		"radeon"
	Screen		1
	Option		"AGPFastWrite"	"True"
EndSection

Section "Monitor"
	Identifier	"Generic Monitor"
	Option		"DPMS"
EndSection

Section "Monitor"
	Identifier	"External Monitor"
	Option		"DPMS"
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Device		"ATI Radeon 9600"
	Monitor		"Generic Monitor"
	DefaultDepth	24
	SubSection "Display"
		Depth		24
		Modes		"1280x854" "1280x1024" "1024x768" "800x600"
	EndSubSection
EndSection

Section "Screen"
	Identifier	"External Screen"
	Device		"ATI Radeon 9600 Card1"
	Monitor		"External Monitor"
	DefaultDepth	24
	SubSection "Display"
		Depth		24
		Modes		"1280x1024" "1024x768" "800x600" "1280x854" 
	EndSubSection
EndSection

Section "ServerLayout"
	Identifier	"Default Layout"
	Screen		"Default Screen"
	Screen		"External Screen"
	InputDevice	"Generic Keyboard"
	InputDevice	"Configured Mouse"
EndSection

So far I have not been able to get the option xinerama to work, but the
clone mode works perfectly. You just have to restart the x-server.

HTH,

Peter
  

I made the modifications suggested by Peter. But nothing happens. At boot, my external monitor keeps white.

Does anybody have an idea?
thanks for your help
