I am running Fedora Core 6 on an Intel Pentium 4 system. I performed a yum update last week, and then yesterday I needed to reboot the machine. Now, after rebooting, the system is unable to start the X Window server.

Here is the error output I get when issuing the startx command:

xauth: creating new authority file /home/tron/.serverauth.2883

I really don't have any idea what is wrong or how to fix the problem.
What can be done to get the X Windows server working again?

tell us more info about your hardware, and also check the log file, as listed in the output there. also provide your /etc/x11/xorg.conf

also did you upgrade from XFree to xorg with that yum update? if so that will lead to some issues. make sure to grab all of the missing packages. as you have no distro listed i can only guess you are running an FC line of distro. the older FC used XFree, the newer vs run xorg.

FC also split several of the packages apart when they converted to xorg like the mouse, keyboard, and monitor.

hope that helps some.

My system is a Pentium 4 running at 1.7 Gigahertz with 512 Megabytes or RAM. It has a 64 Megabyte nVidia GeForce 3 video card.

I do not remember if I upgraded from XFree to xorg. I don't remember seeing anything in the list of upgraded components that indicate the X Windows server was upgrading or changing. There were a lot of components updated when I ran yum last week.

The XOrg.0.log file is about 16 Kilobytes long. I think it would be impractical to lists its entire contents on this forum.

Here is the last portion of the log file that I hope provides enough information:

right, there's something about the new nvidia drivers obseleting older chipsets. read somethign very specific about this on livna, i think you need a seperate package, it's very clearly written there in flashing lights... should explain it all.

Did you try running system-config-display and reconfiguring it? I was reading somewhere that you shouldn't use the vendors drivers because they can cause problems.

system-config-display does not exist on my system, so I cannot run it.

As far as I know I'm using the vendor drivers. I was under the impression I was getting the drivers that were provided by the Fedora Core distribution. The yum update always includes a kmod-nvidia update when there is a kernel update.

I expected that it would have downloaded and installed the proper driver for the latest kernel I updated to.

Where do I find the package that I need to install?
Where is it very clearly written in flashing lights?

clear as day at rpm.livna.org

yum install system-config-*

From the rpm.livna.org website, I executed these two commands:

yum remove kmod-nvidia xorg-x11-drv-nvidia
yum install kmod-nvidia-96xx xorg-x11-drv-nvidia-96xx

and that fixed the problem. I can now run X Windows again.

Thanks for the help.
