[ltp] output to VGA

[chris]

Hi List:

I am trying to get my R50 to use the external screen which uses
1280x1024 resolution rather than my native screen with 1024x768
resolution. 

In my XF86config-4 file I created two screen, monitor sections, as
follows:
Section "Device"
	Identifier	"ATI Technologies, Inc. Radeon Mobility M7 LW [Radeon
Mobility 7500]"
	Driver		"radeon"
	Option      	"AGPMode" 	"4"
	BusID       	"PCI:1:0:0"
	Option		"MonitorLayout" "AUTO"
	Option      	"DPMS"  	"on"
	Screen		0
EndSection

Section "Monitor"
	Identifier	"Thinkpad"
	HorizSync	28-50
	VertRefresh	43-75
	Option		"DPMS"
EndSection

Section "Monitor"
	Identifier	"Hyundai"
	HorizSync	28-50
	VertRefresh	43-75
	Option		"DPMS"
EndSection

Section "Screen"
	Identifier	"Screen0"
	Device		"ATI Technologies, Inc. Radeon Mobility M7 LW [Radeon Mobility
7500]"
	Monitor		"Hyundai"
	DefaultDepth	24
	SubSection "Display"
		Depth		1
		Modes		"1280x1024" 
	EndSubSection
	SubSection "Display"
		Depth		4
		Modes	 	"1280x1024" "1024x768"

	EndSubSection
	SubSection "Display"
		Depth		8
		Modes		"1280x1024" "1024x768"

	EndSubSection
	SubSection "Display"
		Depth		15
		Modes		"1280x1024" "1024x768"

	EndSubSection
	SubSection "Display"
		Depth		16
		Modes		"1280x1024" "1024x768"

	EndSubSection
	SubSection "Display"
		Depth		24
		Modes		"1280x1024" "1024x768"
	EndSubSection
EndSection

Section "Screen"
	Identifier	"Screen1"
	Device		"ATI Technologies, Inc. Radeon Mobility M7 LW [Radeon Mobility
7500]"
	Monitor		"Thinkpad"
	DefaultDepth	24
	SubSection "Display"
		Depth		1
		Modes		"1024x768"
	EndSubSection
	SubSection "Display"
		Depth		4
		Modes	 	"1024x768"

	EndSubSection
	SubSection "Display"
		Depth		8
		Modes		"1024x768"

	EndSubSection
	SubSection "Display"
		Depth		15
		Modes		"1024x768"

	EndSubSection
	SubSection "Display"
		Depth		16
		Modes		"1024x768"

	EndSubSection
	SubSection "Display"
		Depth		24
		Modes		"1024x768"
	EndSubSection
EndSection
Section "ServerLayout"
	Identifier	"Default Layout"
	Screen		"Screen0"
	InputDevice	"Generic Keyboard"
	InputDevice	"Configured Mouse"
	InputDevice	"Generic Mouse"
EndSection

I know the trick is MonitorLayout, which I also tried MonitorLayout
"CRT,None";"CRT,CRT" and "AUTO", I can get the native screen to shut off
but the external screen is running at the resolution of the native
screen, how can I get the external screen to run at 1280x1024 while
shutting the internal screen?
