Unhappy Radeon multihead setup (MergedFB) problems :(

Here is my setup:
Radeon X300 (RV370)
SuSE10.1 (x64)
Xorg 6.8.2
2 x Viewsonic VX2025 20" LCD

I have setup X to run on both LCD screens (primary DVI, secondary VGA) and the desktop spans nicely.

The problem is that on the secondary screen (VGA), the resolution and refresh rates are wrong and the picture is blurry and squished. Both monitors are identical but X doesn't recognize the secondary properly.

Can someone please help, I've been hacking this for days!

OSB output from monitors:
Code:
Primary (good picture)
HFreq: 65.3 KHz
VFreq: 60.0 Hz
Pixel Clock: 146.2 MHz
Resolution 1680x1050

Secondary (blurry, squished)
HFreq: 63.8 KHz
VFreq: 58.8 Hz
Pixel Clock: 120.7 MHz
Resolution 1680x1050

I suppose I will answer my own question since I've figured it out.

Appareantly I needed the Clone and CloneMode options enabled as such:

Section "ServerLayout"
Identifier "Layout[all]"
InputDevice "Keyboard[0]" "CoreKeyboard"
InputDevice "Mouse[1]" "CorePointer"
Option "Clone" "on"
Option "CloneMode" "1680x1050"
Option "Xinerama" "off"
Screen "Screen[0]"
EndSection
