X.org ceases to start

[X-Fi6]

Ah, the classy "init: prefdm main process (NNNN) terminated with status 1" -> "respawning" -> "respawning too fast, stopped". I'm getting this after I think a yum update since it's just appeared out of nowhere on my Fedora 12 laptop.

I'm only the slightest experienced with Fedora. After researching, I understand prefdm is the bash script used in place of startx to start X.org when the OS is booting in Runlevel 5.

I still need a quick rundown on viewing the logs more easily or transferring them over to another machine. I couldn't get iwconfig working so I don't have internet access. The previous two kernel versions in GRUB don't boot, either.

Since it won't even boot past the login screen and I just barely know my way around the CLI, I'd accept any help on this. What do you consider I do after logging in as root in Runlevel 3?

Looking forward to anything.

I would first look into the general message log

cd /var/log

more messages

Look for error messages. Then look into the log file for Xorg

more Xorg.0.log

and see if there are any problems reported.

I see it's a problem with nouveau.
http://phppoll.org/Xorg.0.log

(II) AIGLX error: dlopen of /usr/lib64/dri/nouveau_dri.so failed (/usr/lib64/dri/nouveau_dri.so: cannot open shared object file: No such file or directory)

I'll get right on to a yum update and yum reinstall xorg-x11-drv-nouveau or xorg-x11-drivers.

Edit: Absolutely NO luck. Still the same errors even after a yum remove xorg-x11-drv-nouveau, yum install xorg-x11-drv-nouveau. I get "libgmodule-2.0: Invalid ELF Header" in one of the messages during init 5, so I did yum install glib and it made no change. Init 5 gives me the same errors as always at the end, however: prefdm terminated with status 1.

/var/log/Xorg.0.log is the same as before, and messages and boot.log are empty.

What do you suppose I do now?
