Hello,

Graficcards

PCI-E Nvidia Geforce 6800 ( dual head )
PCI    Nvidia TNT 2

3x 19" LG 1950 Flatron Monitor

DualView Works Fine.

But i can get working the 3nd Monitor ( Right Display)

Here is my xorg.conf works perfectly with startx -- -layout TwinView
If i try startx -- -layout Xinerama , just the 2 same Monitor works like TwinView, the Right TFT doesent work (Black Screen)
I Hope someone can help me to get my 3nd Monitor work.

Re: 3 Monitor under Linux

twinview does support more than two monitors i think. Also:

Option "MetaModes"  "1280x1024,1280x1024;

shouldn't this be Option "MetaModes"  "1280x1024,1280x1024,1280x1024;

if you wanted to specify three monitors? and why do you have 4 monitors sections if you have 3 monitors?

I don't know... i hate xorg.conf: it's the crux of linux.

Yes you are right, TwinView can only handle 2 Monitors

Option "MetaModes"  "1280x1024,1280x1024;

shouldn't this be Option "MetaModes"  "1280x1024,1280x1024,1280x1024;.

Wrong this line is for TwinView Only.

if you wanted to specify three monitors? and why do you have 4 monitors sections if you have 3 monitors?

I Just Specify 3.

Re: 3 Monitor under Linux

Okay i Know the Problem.

Geforce6800 works with drivers nvidia-beyond
Riva TNT dont work with nvidia-beyond it need nvidia-legacy-beyond

sudo pacman -S nvidia-legacy-beyond
:: nvidia-legacy-utils conflicts with nvidia-utils. Remove nvidia-utils? [Y/n] N

Some Solution?
