I upgraded from Fedora Core 4 to version 5, and forgot to backup my Xorg.conf file before doing so. After downloading and installing NVIDIA-Linux-x86-1.0-8762-pkg1 video driver package, I restored a version of my xorg.conf file that had been working with an earlier version of the Nvidia.com driver and the same video card that I am currently using,and issued a "startx" command.

The X server quickly exits, with a few errors:

Failed to load module "glx" ( a required sub module could not loaded )
Failed to load module "nvidia" ( module does not exist )


By issuing "lsmod" command, I see the nvidia module is loaded, but the glx module is not.



Any ideas on how to fix this? If I change xorg.conf to use "nv" module in the device section, then it does not complain about glx, but it does say that "specified device already in use". To get rid of that error, I commend out the "Bus ID" line for the second "Device" in xorg.conf, which then lets X server start, but with only a single display.

To recap:
Fedora Core 5
NVIDIA-Linux-x86-1.0-8762-pkg1
Nvidia 6600GT AGP card
2xAcer AL1912 LCD display. on one VGA and the other on DVI output.
This configuration worked in FC4 ( same everything except for xorg.conf. )


Thank You.

Xinerama is not Twin View. Xinerama is X11 way of handling more than one monitor from multiple cards or multiple outputs from a card. Twin View is nVidia's way of handling their card's multiple outputs with ease. Xinerama needs the bus PCI ID to handle multiple cards and outputs.

What I read, Fedora uses a different method to install from proprietary modules (drivers). Read http://www.fedorafaq.org/#nvidia for the proper way of installing nVidia software in Fedora 5.

You need make sure the nvidia module is loaded before X Window System starts. If you have nvidiafb or rivafb loaded upon boot up, the nvidia module will not work and you will not be able to use GUI.

Like Windows, I do not recommend updating the present installation of Fedora to the latest. It is better and recommended by Fedora and other distributions to do a clean installation.

I got it figured out. It wasn't my xorg.conf that was the problem, I needed it install the kmod-devel package ( with in turn had a dependency on a x11- something package ) and then my dual head setup worked perfectly. I am wondering if I am even using the drive that I dl'd from Nvidia..but that is a question for another day.

I am no longer watching this thread, but feel free to add comments here.
