hi, i have an nvidia geforce 6800le card, and i'm trying to get my second monitor working with Xinerama, problem is, i think i've configured everything right, yet when i startx the second monitor just is a CLONE of the primary one
here 's my XF86Config

Correction , i found out the problem => see the typo "Screen0 instead of "Screen " :s

yet now i have another problem, i can't get my second monitor to anything higher than 640*480 though it can do 1024*768

does anyone have a clue why ?

I think it might have something to do with you using Xinerama and Twinview. Here is all I added to my xorg.conf to make it work.

Section "Device"

Identifier "Nvidia 6800 GT"
Driver "nvidia"
Option "RenderAccel" "true"
Option "NvAgp" "1"
Option "TwinView" "True"
Option "SecondMonitorHorizSync" "30-80"
Option "SecondMonitorVertRefresh" "60,75"
Option "MetaModes" "1280x1024, 1280x1024; 1280x1024, 1280x1024;"
Option "TwinViewOrientation" "LeftOf"
Option "Xinerama" "on"

EndSection

The nvidia docs have a lot of information in them also.
