Thumbs down Twinview Two LCD Different LCD Displays

I have a Dell Dimension 4700 with a GeForce 6800 from them. This card has a vga head and a DVI head. On the vga head, I have a Samsung SyncMaster 170N and on the DVI, I have a Dell 2005 FPW (wide screen). Currently I am successful in running both monitors but with a very generic configuration. I want the desktop to span which it IS doing. However, I want to run diffferent resolution for the obvious reason of the aspect ratios being different. I have tried many different recommendations, to no avail. Either the Dell Monitor comes up with Cannot display this mode, or the monitor doesn't receive a sig at all. Here's my working xorg.conf as it stands now....relevant lines only.

Section "ServerLayout"
Identifier "single head configuration"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

Section "Module"
Load "dbe"
Load "extmod"
Load "fbdevhw"
Load "glx"
Load "record"
Load "freetype"
Load "type1"
# Load "dri"
# Load "dri"
EndSection

Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Samsung SyncMaster 171N/175N/171Np/171Nm/CX174N/CX171N/MX$ DisplaySize 430 270
HorizSync 30.0 - 81.0
VertRefresh 56.0 - 76.0
Option "dpms"
EndSection

Section "Monitor"
Identifier "Monitor1"
VendorName "Monitor Vendor"
ModelName "Dell 2005 FPW"
DisplaySize 430 270

Section "Device"

VendorName "Videocard vendor"
BoardName "NVIDIA GeForce 6800 (generic)"
Option "TwinView" "true"
Option "MetaModes" "1024x768,1024x768;800x600,800x600"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"

SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280x968" "800x600" "640x480"
EndSubSection
SubSection "Display"

Modes "1680x1050" "1280x1024" "1280x968" "1152x864" "1024x76$ EndSubSection
EndSection

Now, I know there are some elements missing. That's why I turn to you....my dear forums.

What I am after is to run the Dell 2005fpw on the DVI head at 1280x968, and the Samsung on the vga head at 1280x1024.

It has to be a simple configuration change, doesn't it? I thought I scoured enough through the NVIDIA documentation and perused this site only to come up empty. If someone could just give me a sample config of what I need to add, and where i need to add it, I would appreciate it AND buy you a beer.

Hmm, sth. is wrong with your xorg.conf (but, probably just a copy&paste - error)

Code:
Modes "1680x1050" "1280x1024" "1280x968" "1152x864" "1024x76$ EndSubSection
should be:
Code:
Modes "1680x1050" "1280x1024" "1280x968" "1152x864" "1024x768" 
EndSubSection
and why do you have 2 diffrent modes for the same colour-depth?

SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280x968" "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1680x1050" "1280x1024" "1280x968" "1152x864" "1024x768" EndSubSection
EndSection




Hmm, what _Driver_-Version do you use?
(Ever tried the 6629 one?)

EDIT: can you also attach a your xorg.log (look in /var/log)?

Yeah, that was a copy and paste malfunction....nano, it rocks in some ways, and stinks in others.

should be:
Code:
Modes "1680x1050" "1280x1024" "1280x968" "1152x864" "1024x768" 
EndSubSection

See! i just need some explanation of what the different sections do! If I would have known it wouldn't have been there. Actually that part of the config I found on a website somewhere.

7676...and I forgot to mention one important tidbit of info....it's a PCI Express card.

can you also _create_ one xorg.log with different resolutions (as you actually wanted to do)?


BTW:if you want to try 6629:


Get it here


you'll also need to patch it:
patches + instructions (please, read the whole thread first!

I'm willing to try anything...however, what is 6629 going to do that 7676 isn't? Did I mention I have a PCIexpress card?

II) NVIDIA(0): NVIDIA GPU detected as: GeForce 6800
(--) NVIDIA(0): VideoBIOS: 05.41.02.17.25
(II) NVIDIA(0): Detected PCI Express Link width: 16X

so you probably have a 6800 NU & nForce 4 Board, or?

and PCI-Express & 6800 GPU are supported since 6106... (but 6106 won't compile!)


Well, 6629 was the last _version_ where twinview (with different resolution) worked for me... but never with any 7xxx. I don't know why, (but it's probably because 7xxx always set the same resolution & refresh-rates for both monitors...
even if if I forced
Option "MetaModes" "DFP-0: 1280x1024, CRT-0: 1024x768")
