[SOLVED] Dual Monitor / General Xorg.conf Issue

I cannot get my second monitor to work. It is a Dell SE198WEP. My other [working] monitor is a Dell SE198WFP. I suspect my xorg.conf file is not good, but I'm not sure how to fix it. Thanks for any help.

Re: [SOLVED] Dual Monitor / General Xorg.conf Issue

I simply use xrandr to use dual heads like this. Here's my xorg.conf which defines the 2 monitors and their resolutions. Then a simple xrandr command to set up the screens. Works great in i3

Section "Device"
        Identifier      "ATI Technologies HD2400XT Pro"
        Driver          "ati"
EndSection
Section "Monitor"
        Identifier      "DVI-0"
        Option          "DPMS" "true"
EndSection
Section "Monitor"
        Identifier      "DVI-1"
        Option          "DPMS" "true"
EndSection
Section "Screen"
       Identifier       "Default Screen"
       Device           "ATI Technologies HD2400XT Pro"
       Monitor          "DVI-0"
       DefaultDepth     24
   
       SubSection "Display"
           Depth                24
           Modes                "1680x1050" "1050x1680" "1280x1024" "1440x900" "1280x800" "1152x864" "1280x720" "1280x768" "832x624" "800x600" "640x480" "720x400"
           # ADD A VIRTUAL LINE TO PROVIDE FOR THE LARGEST SCREENS YOU WILL HOTPLUG 
           Virtual              2960 2960 
       EndSubSection
EndSection

and then in .xinitrc before starting my wm

xrandr --output DVI-1 --auto --right-of DVI-0
