xrandr not detecting 2nd monitor

when I execute xrandr, I get:

    Screen 0:minimum 320 x 175, current 1280 x 1024, maximum 1280 x 1024

but when I boot crunchbang, I get two screens:

    VGA-0

    DVI-I-1

I've been trying to get my setup working where I have a one big screen of 2560x1024 (two 1280x1024). I can manage to get a clone but what is the point of that?

Also, if I am using vesa driver, I gel a cloned screen. Then if I change to nv driver, the right screen goes black/blank and xrandr gives me one screen which is "Screen 0"

Will try to download driver from nvidia website and install.

Re: xrandr not detecting 2nd monitor

after so many failed attempts using downloaded drivers and changes with xorg.conf (TwinView option), and with no luck with "xrandr", I decided to try and give the nv driver a second chance. With a little bit more research, I found out that with nv open source driver, you use an option called "dualhead" and not "twinview". Gave it a shot and boy oh boy oh boy. IT WORKED!

The settings that did it for me for those who want to know:

Section "Device"

       Option "DualHead" "True"

EndSection

Section "Screen"

       SubSection "Display"

           Virtual 1280 1024

       EndSubSection

EndSection

There are more entries on these section of course but these are the ones that made it work.

By the way, the main reason why I wanted xrandr to work is for me to have a ONE BIG SCREEN. Two 2560x1024 (Two 1280x1024)
