nvidia twinview not working on 8.3

E

edwinoakes

Have been unable to find the correct xorg.conf configuration to implement nvidia twinview using a GeForce 9500 GT and two flat panel monitors. The OS is FreeBSD 8.3 with gnome2. Monitors are an acer V234H with 1920x1080 resolution and a LG L1953ss with 1280x1024 resolution.

If I boot the computer with no xorg.conf present both monitors have the identical display. I have set and saved the resolution of the acer monitor to 1920x1080 in the gnome monitor dialog.

Starting X with my current xorg.conf the LG monitor has a black screen. The acer has a virtual screen of 3200x1080 qnd displays 1920x1080.

I have searched the web and read the nvidia README at http://us.download.nvidia.com/freebsd/180.44/README/index.html to try to find the error. I have tried many options.

the display section is of xorg.conf is:

The pertinent section of Xorg.0.log is:

There is no twinview option in my version of # nvidia-configure.

I have put the entire Xorg.0.log on pastebin at http://pastebin.com/wqDLqhp4

The entire xorg.conf is at http://pastebin.com/6krq0FA3

The Xorg.0.log file from starting X with no xorg.conf is at http://pastebin.com/xATDCWVD
 
I think your pastebin link is wrong. I cannot see your configuration, but I have a working configuration:

- You need Screen definitions for your monitors:
Code: 
Section "Screen"
        Identifier      "T520_TV"
        Device          "NVS4200M_TV"
        Monitor         "LCD"
        DefaultDepth    24
        SubSection      "Display"
                Depth   24
                Modes   "1600x900"
        EndSubSection
EndSection

Section "Screen"
        Identifier      "LG_W2486L"
        Device          "NVS4200M_TV"
        Monitor         "LCD"
        DefaultDepth    24
        SubSection      "Display"
                Depth   24
                Modes   "1920x1080"
        EndSubSection
EndSection
- You need a Device definition:
Code: 
Section "Device"
        Identifier              "NVS4200M_TV"
        Driver                  "nvidia"
        BusID                   "PCI:1:0:0"
        Option "TwinView"
        Option "MetaModes"              "DFP-1: 1920x1080, DFP-0: 1600x900"
        Option "TwinViewOrientation"    "DFP-0 LeftOf DFP-1"
        Option "TwinViewXineramaInfoOrder"      "DFP-1, DFP-0"
EndSection
- And finally a ServerLayout:
Code: 
Section "ServerLayout"
        Identifier      "HD"
        Screen          1                       "T520_TV"
        Screen          0                       "LG_W2486L" 0 0
        InputDevice     "SysMouse"              "CorePointer"
        InputDevice     "Keyboard"              "CoreKeyboard"
        Option          "AIGLX"                 "on"
        Option          "AllowEmptyInput"       "off"
EndSection

The composite extension is enabled in my configuration.

I hope this helps. You can test and try some settings with the nvidia-settings package.
 
I fixed the postbin URL for my xorg.conf file in my first post.

I have succeeded in getting twinview to work, almost the way I want. My problem was mainly in the option metamode line. I had misinterpreted the order of the parameters.

The only thing not working is that the gnome2 top and bottom panels show on the second small monitor. If I click on the left hide buttons of those panels, they move to the primary monitor, but they only go about 2/3 of the way across. Not a big deal!
