Log file

This log file just captures X starting up, I need the logfile of when you
logout, so you might need to look for the .old version of the log file depending
on your setup.

Xorg Log files

Unfortunalely, none of these show X logging out.

So can you disable your login manager, and start X manually (probably from a
network connection), and logout.

The attach a copy of Xorg.0.log, you might also be able to get a gdb backtrace
via a network connection if you really think X is hanging on logout.

Alan , i tried all the above said ways .
When i tried running Xorg -configure , i only get a blank screen and system 
freezes so its being disconnected from the network .Also startx is just giving a
blank screen and when i try to kill it by 
ALT+CTRL+Backspace ,the system hangs .  

X also hangs when i try to attach it to GDB .  

Why are you running X -configure ?? I thought you said it's a logout issue ??

If things are hanging with the network connection, try a serial connection.

Without a decent logfile I've got absolutely no idea where it could be
crashing/hanging.

I tried using serial connection , but again i could not get any logs. 
Until now i have been using Suse 10.2 X86_64 on my PC , but just yesterday i
have installed Suse 10.2 32 bit OS  as my processor is of EM64T type .(Intel's
64 bit version) and I noticed that everything works fine with X now .X never
crashes now . So ,looks like there is an issue with i810 driver complied for 64
bit architecture. 

*** Bug 9305 has been marked as a duplicate of this bug. ***

I have exactly this problem - it is a real problem.

I run FC5, whenever X is reset - bam - nothing after that.  No log shows any fault just a complete lock up of the system.

System runs perfectly except for this problem. I have resigned myself to never resetting the X server, ie never logging out from a session.

The simplest method to reproduce the fault is to bring the system up in level 3, login and enter xinit. When I exit from the xterm - lock up occurs.... so it is not the WM or any other application.  xterm runs fine if started from within a a WM.

I have wasted days looking for any clues in logs etc, and trying all manner of options for the xorg.config annd kernel.

The following may be relevant or related

I will help if I can, but I will need explicit instructions.

BTW I am running x86_64

More details:
1. i810 driver works running i386 kernel (puppy live CD linux), problem may be related to x86_64 only.
2. Logs show nothing prior to the crash. (dmesg, messages, Xorg)
3. vega driver (in x86_64) resets ok.  vesa is tediously slow, I cannot play a DVD with the vega driver.  power off does not work either.

At last i am relieved from this problem . I simply compiled kernel 2.6.20 for 64 bit architecture and booted it and my X server never hangs on logout. I still did not understand the cause for the problem. 

I just installed the newly released FC5 kernel update via yum, details (uname -u):
...2.6.19-1.2288.fc5 #1 SMP Sat Feb 10 14:59:35 EST 2007 x86_64 x86_64 x86_64 GNU/Linux
For the first time in nearly a year I can logout of the wm without crashing the system....

Kernel bug. Closing.
