NVidia drivers using external output not built in LCD.


Hey all, I have finally gotten my NVidia drivers installed on my fresh FC7 install. GLX is working also... which was what started this whole witch hunt. Ok now the problem has shifted to the fact that my XServer is demanding to use the external video output and not the laptop LCD. When I try and force the configuration to disable the external port and use the default LCD, Xserver just goes blank and the system becomes unresponsive.

Upon booting the system utilizes the laptop LCD and will not auto start XServer. I do not know where to go from here but I will post anything output/log files that someone thinks might help.

Thanks in advance!

Look in the xorg.conf man page. I think you need to add a BusID entry to each graphics device section and then make sure that the DevID identifier references the correct graphics device.
Code:
       BusID  "bus-id"
              This  specifies  the  bus  location  of  the graphics card.  For
              PCI/AGP   cards,   the    bus-id    string    has    the    form
              PCI:bus:device:function  (e.g., "PCI:1:0:0" might be appropriate
              for an AGP card).  This field is usually optional in single-head
              configurations  when using the primary graphics card.  In multi-
              head configurations, or when using a secondary graphics card  in
              a  single-head configuration, this entry is mandatory.  Its main
              purpose is to make an unambiguous connection between the  device
              section  and  the hardware it is representing.  This information
              can usually be found by running the Xorg server with the  -scan‐
              pci command line option.
Log out of X, switch to runlevel 3 and run "X -scanpci".

Code:
           Section "Screen"
               Identifier "name"
               Device     "devid"
               Monitor    "monid"
               entries
               ...
               SubSection "Display"
                  entries
                  ...
               EndSubSection
               ...
           EndSection

Ok, I read through that section and it appears to be what I am searching for. I tried to run "X -scanpci" and I received an error saying that "that module is not installed." I was able to get the BusID for my GeForce GO 7800 GTX from the NVidia X Server Settings, (2:0:0). I could not figure out which xorg package to install to get "X -scanpci" to work so I had to find a workaround.

Is the BusID for the video card what I am looking for or will there be a separate one for the monitor? Sorry for being a complete noob.

There will be one for both of the graphic devices.
The /sbin/lspci should return the same info.

It appears that there is only one BusID for the card. Here is the working xorg.conf file that will load XServer onto the external video port:

The above config will run Xserver and result in a black screen and unresponsive system. I have tried manually entering a Screen1 and Display1 and setting the server to use either and they both result in the same situation.

From your lspci listing:
Code:
02:00.0 VGA compatible controller: nVidia Corporation G70 [GeForce Go 7800 GTX] (rev a1)
So use "2:0:0" as the BusID:
Code:
Section "Device"
    Identifier     "Videocard0"
    BusID          "2:0:0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce Go 7800 GTX"
EndSection
I haven't studied the rest of your xorg.conf settings. Maybe start with what your config program sets and insert the BusID line.

You said that you have both an onboard video interface and a card. However your lspci didn't contain any information on the onboard video that I could see. That could be part of the problem.

I looked at my "Module" section, and it looks similar to yours.

Also, see if you can check if you have the correct monitor selected. I think you might want to try at least a generic lcd monitor at the native resolution of your monitor.

As well, look through your xorg.log ( it may be named like: /var/log/xorg.0.log ).
Look for (EE) entries. If you use less, you can jump to the next error by typing:
/EE
