Problem setting up dual monitors

I'm having trouble setting up dual monitors.When i boot into my login screen,both monitors turn on for a second or two and then they both shut off and I'm taken to the command line.Here is my 10-monitor.conf file:
-- MOD EDIT -- Use code tags --Inxsible

Section "ServerLayout"
    Identifier     "DualSreen"
    Screen       0 "Screen0"
    Screen       1 "Screen1" RightOf "Screen0" #Screen1 at the right of Screen0
    Option         "Xinerama" "1" #To move windows between screens
EndSection

Section "Monitor"
    Identifier     "Monitor0"
    Option         "Enable" "true"
EndSection

Section "Monitor"
    Identifier     "Monitor1"
    Option         "Enable" "true"
EndSection

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    Screen         0
EndSection

EndSection

    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "TwinView" "0"
    SubSection "Display"
        Depth          24
        Modes          "1920x1080__60.00"
    EndSubSection
EndSection

Section "Screen"
    Identifier     "Screen1"
    Device         "Device1"
    Monitor        "Monitor1"

I believe you will need to identify the location of each graphics card by adding the appropriate

    BusID          "PCI:1:0:0"

to each device section

Any reason you're using xinerama instead of TwinView?

Re: Problem setting up dual monitors

Please search the forums. There are many posts for this issue. Also use code tags around any output or file that you paste

Re: Problem setting up dual monitors

If they both turn on for a second or two and then it drops you back at the command line, it would appear that X is working ok.

What wm/de are you using? .... or maybe what login manager are you using?

Have you checked your /var/log/Xorg.0.log file to see what it says?
Normally when you are dropped to the command line, there would be an error message on the screen in front of you; it should be the same as in the log file, btw. 

Also, when did this start happening?
Has it ever worked?  If so, what changed?

Re: Problem setting up dual monitors

I recommend using twinview instead of xinerama. I remember reading somewhere that xinerama doesn't play well with the proprietary nvidia drivers.
