Description:

When I logout from KDE Xorg crashes, this happens consistently everytime I login, whether I start KDE via kdm with init:

x:5:respawn:/usr/bin/kdm --nodeamon

or

x:5:once:/etc/rc.d/kdm start

Or U call the /etc/rc.d/kdm start script from a console.

The kdm process continues to run although X has crashed.

I've never had any trouble starting X by restarting kdm, even after a crash.

Additional info:
* package version(s)

Most of my KDE packages are either at version 4.3.0-1 or 4.3.0-2 my system is up to date as of August 13, 2009 except for my curl package, which I doubt matters. I can't figure out to tell what version kdm is nor what package provides it.

* config and/or log files etc.

I've attached the whole Xorg.0.log.old, but I think this is the significant part:

(EE) intel(0): Failed to initialize kernel memory manager
(==) intel(0): VideoRam: 262144 KB
(II) intel(0): Attempting memory allocation with tiled buffers.

Fatal server error:
Caught signal 11. Server aborting

I've attached my /var/log/kdm.log as well, note that it contains some entries pertaining to my current, not yet crashed session
of KDE, as well as the previous session that crashed.

I'll atach the kdmrc file too

Steps to reproduce:

Start KDM, logout of KDE.
