Configure XRandR at Server Start - what am I doing wrong?

[gzunk]

I'm trying to configure my dual head to that it's the way I want at server startup. I think I'm doing everything correctly, but it's not working. I'm using fglrx 8.62.4, which is 8.6 I believe. Here is my xorg.conf:

Section "ServerLayout"
	Identifier     "aticonfig Layout"
	Screen      0  "aticonfig-Screen[0]-0" 0 0
EndSection

Section "Files"
EndSection

Section "Module"
EndSection

Section "ServerFlags"
	Option	    "DontZap" "off"
EndSection

Section "Monitor"
	Identifier   "Samsung_SM305T"
	Option	    "PreferredMode" "2560x1600"
	Option		"DPMS"	"true"
EndSection

Section "Monitor"
	Identifier   "GNR_TS2000H"
	Option "RightOf" "Samsung SM305T" 
	Option "Rotate" "left"
	Option "DPMS"	"true"
EndSection

Section "Device"
	Identifier  "FGLRX_Video_Device"
	Driver      "fglrx"
	BusID       "PCI:3:0:0"
	Option "DFP1" "Samsung_SM305T"
	Option "DFP2" "GNR_TS2000H"
EndSection

Section "Screen"
	Identifier "aticonfig-Screen[0]-0"
	Device     "FGLRX_Video_Device"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     24
		Virtual	4160 1600
	EndSubSection
EndSection

But this doesn't do anything and I have to run the following command when I log in to get the screen looking the way I want it:

xrandr --output DFP1 --auto --output DFP2 --auto --rotate left --right-of DFP1

Which works. What I am doing wrong?

Thanks!

In the Device section, try changing

Option "DFP1" "Samsung_SM305T"
Option "DFP2" "GNR_TS2000H"

to

Option "Monitor-DFP1" "Samsung_SM305T"
Option "Monitor-DFP2" "GNR_TS2000H"

Just tried it, no joy. It gave me blank screen on startup, with the second monitor powering down into sleep.

SSH also wouldn't work, so I had to power the machine down and boot into safe mode to change the setting back...

Any other ideas?
