Nvidia TwinView XF86Config-4 problems

I'm trying to get the dual-head working on my GeForce4 ti4400 on Mandrake 9.2. I don't think i totally understand what they're trying to say with configuring the XF86Config-4 file. I get an error when trying to start X with the other screen enabled. I know the driver itself is working because when I startx i see the nvidia logo. Here i a copy of my XF86Config-4 and below that is what error I get. Some stuff is cut out that didn't really have anything to do with it, but I think this is all the information I have that you could use to help me.

And here is basically what it says when I startx.

[code[

(EE) NVIDIA(0): ************** Aborting **************
(EE) Screen(s) found, but none have a useable configuration.

Fatal Server Error:
no screens found
[/code]

Thanks a lot for any help.

you have listed no mode sizes at all! for example:

Section "Screen"
    Identifier  "nvidia1screen"
    Device      "nvidia1"
    Monitor     "iiyama"
    DefaultDepth 24
    Subsection "Display"
        Depth       24
        Modes       "1280x1024" "1152x864" "1024x768" "800x600" "640x480"
        ViewPort    0 0

my full (non twinview using) geforce dual head config is... http://thirtythreeandathird.net/dualhead

Hmm I don't think it' the same with the TwinView. It says in the readme all the dual moniter stuff is handled within the driver so we shouldn't even have to specify multiple screens. Well except for what you are supposed to specify in the Device section like like ranges and modes. (or is some part of that wrong?) Any other ideas?

Thanks guys.

hey I still haven't solved this problem. What should the XF86Config-4 file look like with twinview enabled?

Thanks for the help.

Here is some additional information that might help anyone that is willing to help me. I have my xfree86.0.log here. Theres way too much information in there for my newbie mind to comprehend. The key lines though I thought might give some idea of the problem are as follows:

(II) NVIDIA(0): Connected display device(s): CRT-1, DFP-0
(--) NVIDIA(0): Detected TV Encoder: Brooktree 871
(WW) NVIDIA(0): Multiple displays connected, but only one display allowed;
(WW) NVIDIA(0):      using first display

Both monitors are identical LCD displays. The first one is on VGA the second is on DVI.

Thanks for the help.

setup your config for single monitor display, and then use YanC to configure it, its a GUI, and really makes it easy to get all setup...thats what i used, and here is a copy of my file...


Option "NvAGP" "3"
Option "DigitalVibrance" "132"
Option "TwinView" "1"
Option "SecondMonitorHorizSync" "31-64"
Option "SecondMonitorVertRefresh" "50-90"
Option "TwinViewOrientation" "RightOf"
Option "TVStandard" "NTSC-M"
Option "MetaModes" "1792x1344@1792x1344,1792x1344@1792x1344;1600x1200@1600x1200,1600x1200@1600x1200;1280x1024@1280x1024 ,1280x1024@1280x1024"
EndSection

Thanks for the tip SLaCk_KiD, I downloaded YanC and used it to configure. I got the same error when starting up X. Since this program configured it for me, I assume there are no problems with my configuration files. Could this mean that there is a problem with the driver or a compatability issue? I don't know. Here is the device section that YanC wrote:

Section "Device"
    Identifier "device1"
    VendorName "NVidia"
    BoardName "NVIDIA GeForce4 (generic)"
    Driver "nvidia"
    Option "DPMS"
    #Option "TwinView" "1"
    #Option "SecondMonitorHorizSync" "24-83"
    #Option "MetaModes" "1280x1024 @1280x1024,1280x1024 @1280x1024"
    Option "NvAGP" "3"
    Option "DigitalVibrance" "0"
    #Option "SecondMonitorVertRefresh" "55-85"
    #Option "TwinViewOrientation" "RightOf"
    #Option "TVStandard" "NTSC-M"
EndSection

OK, here's another question. Do I have to have two monitor and two screen sections? one for each display?

no you dont need a second screen or monitor section, the config has it right there. you need to uncomment the option lines...

Option "TwinView" "1"
Option "SecondMonitorHorizSync" "24-83"
Option "MetaModes" "1280x1024 @1280x1024,1280x1024 @1280x1024"
Option "NvAGP" "3"
Option "DigitalVibrance" "0"
Option "SecondMonitorVertRefresh" "55-85"
Option "TwinViewOrientation" "RightOf"
Option "TVStandard" "NTSC-M"

so it should look like that. and if that still doesnt work, then post the output of the /var/adm/XFree86.0.log, i mgiht notice something that isnt correct. I dont knwo if you are new to linux or not, so i dont want to try to sound like a know-it-all, jsut a suggestion.

Sorry it took me so long to reply. Things have been crazy busy over here. Those lines actually were uncommented when i tried it, I had to comment them out so I could start x. The log wasn't in the place you told me but I did find it in /var/log/XFree86.log. You can get that file here. Its actually a slightly older log from before i made these changes, but it's the same error.

i was using

Option "MetaModes" "1024x768, 1024x768"

instead of

Option "MetaModes" "1280x1024, 1280x1024"

and i changed the "Virtual" to "Modes" in the "Screen" section:

Subsection "Display"
Depth 24
Virtual 1280 1024
EndSubsection

to

Subsection "Display"
Depth 24
Modes "1280x1024"
EndSubsection

HEYYY!!! It worked. Thanks so much orikerus, i guess the problem was just that I had to change virtual to modes and it worked. This is great, I've been trying to get this forever.

Thanks.
