    [SOLVED] S-Video and VGA


    Hi everyone-

    I am running a new setup and am having some issues. I currently have one VGA out on from integrated video and recently got a GeForce 7200GS which has VGA, DVI and SVideo out. I would like to run either VGA or DVI to my monitor and the SVideo to my TV. My monitor is working fine (VGA from the new card, but I could also run it off of the integrated video output as well), but my current setup doesn't send anything to the SVideo.

    I would like to run 2 X sessions (either all the time, or start up the second one when I want it). One of the X-sessions would use my VGA device and the other would use the SVideo.

    Does anyone know what I need to add to my xorg.conf (or maybe more) to get the SVideo working?

    Seth

    Additional Information:

    I've tried several options, but by following some advice from the gentoo (and related) Dual Monitor wiki page, I think that TwinView is the option I am looking for. However, I have had only limited success getting it right. I can either get an xsession running on my monitor or the TV, but not both. Here is what I have in my xorg.conf right now:

    Code:
    Section "Device"
         Identifier  "geforce7200"
         Driver      "nvidia"
    #     BusID		 "PCI:3:00.0"
         Screen 0
         VideoRam    512
        #TV Out Setup
    #     Option "TwinViewXineramaInfoOrder" "CRT-0"
    #     Option "ConnectedMonitor" "CRT-0,TV"
         Option	"TwinView"
         Option "TwinViewOrientation" "LeftOf"
         Option "MetaModes"   "1440x900 , 1360x768 ; 1152x768 , 1152x768"

         Option	"TVOoutFormat" "SVIDEO"
         Option	"TVOverScan" "0.6"
    EndSection

    Anyone see where I went off the rails?

    I've partially cracked this nut, but there is one remaining issue. I currently can get both x-sessions running. (one on my monitor and one on my lcd). While both can be running at the same time, when I switch from one to the other using ctl-alt-F7/8 the other monitor shuts off. The other issue has to do with the picture quality. When I start the additional x session and send it to the tv the colors look good, but the colors on my lcd look very washed out. If anyone can help me out please do, but for now I'll just post my xorg.conf file that I'm using for my current setup.

    Code:
    Section "Device"
         Identifier  "geforce7200 1"
         Driver      "nvidia"
         Screen 0
         VideoRam    512
         Option    "RenderAccel" "true"
    EndSection

         Identifier  "geforce7200 2"

         Option    "RenderAccel" "true"
         Option "TVOutFormat" "SVIDEO"
         Option "UseDisplayDevice" "TV"
         Option "ConnectedMonitor" "TV"
    EndSection
    
    Section "Screen"
        Identifier  "Screen0"
        Device      "geforce7200 1"
        Monitor     "hannsg"
        DefaultDepth 16
        
        Subsection "Display"
            Depth       16
            Modes       "1440x900" "1360x768" "1024x768" "1152x768" "1360x768"
            ViewPort    0 0
            Virtual     0 0
        EndSubsection
        
        Subsection "Display"
            Depth       24
            Modes       "1440x900" "1280x1024" "1024x768" "1400x1050" "640x400"
            ViewPort    0 0
            Virtual     0 0
        EndSubsection
    EndSection
    
    
    Section "Screen"
        Identifier  "Screen1"
        Device      "geforce7200 2"
        Monitor     "olevia"
        DefaultDepth 16
        
        Subsection "Display"
            Depth       24
            Modes       "1360x768" "1280x1024" "1024x768" "1400x1050" "640x400"
            ViewPort    0 0
            Virtual     0 0
        EndSubsection
        Option "TVOutFormat" "SVIDEO"
        Option "UseDisplayDevice" "TV"
    EndSection 
    Section "ServerLayout"
        Identifier  "lcd"
        Screen 0 "Screen0"
        Screen 1 "Screen1" 
        InputDevice "Mouse1" "CorePointer"
        InputDevice "Mouse0" "AlwaysCore"
        InputDevice "Keyboard1" "CoreKeyboard"
    EndSection
    
    Section "ServerLayout"
        Identifier "tv"
        Screen 0 "Screen1"
        InputDevice "Mouse1" "CorePointer"
        InputDevice "Mouse0" "AlwaysCore"
        InputDevice "Keyboard1" "CoreKeyboard"
    EndSection
    I can then start the x-session on the TV by using:

    startx -- :1 -layout tv

    Well, this wasn't the solution I was looking for, but it at least works. I have given up trying to use the s-video cable for now. It seems, for some unknown reason, that once any x session which is using the s video out starts, it changes the way the colors/brightness/contrast is also output. This gives my monitor an extremely washed out look that is uncorrectable via any of the aforementioned settings.

    Solution which works:

    VGA to the LCD TV
    DVI to my regular LCD monitor.

    The color looks good on both.
