KWin compositing only in XRender mode / unable to use OpenGL mode.

Question

Hi,
somehow I am unable to activate kwin4 compositing in OpenGL mode. If I try to I get the following message:
"Failed to activate desktop effects using the given configuration options. Settings will be reverted to their previous values.
Check your X configuration. You may also consider changing advanced options, especially changing the compositing type."
I have a NVidia GF GTX+ 9800 connected to 2 monitors in twinview.
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
Option "DamageEvents" "True"
Option "RenderAccel" "True"
Option "AllowGLXWithComposite" "True"
Option "TwinView" "1"
Option "TwinViewXineramaInfoOrder" "CRT-0"
Option "metamodes" "CRT-0: nvidia-auto-select +0+0, CRT-1: nvidia-auto-select +1600+0"
Option "AddARGBGLXVisuals" "True"
SubSection "Display"
Depth 24
EndSubSection
EndSection
I've turned xdamage and xcomposite on.
Section "Extensions"
Option "Composite" "True"
Option "DAMAGE" "True"
Option "RENDER" "True"
EndSection
I made sure I am not in failsafe mode.

I think I've the latest drivers and software installed.
nvidia 190.42-1
xorg-server 1.7.1.901-2
kdebase-workspace 4.3.3-1
xorg.conf: http://longint.de/~blq/xorg.conf

Xorg.0.log: http://longint.de/~blq/Xorg.0.log
glxinfo: http://longint.de/~blq/glxinfo.output
What else could I check? Any suggestions?
Thanks in advance.

Please try with Compiz instead of KWin.  I asked another user with a similar issue to do this and it helped them, because Compiz gave a better error message that helped them diagnose the issue.  And if Compiz works fine, it's a KWin bug

Ok, I weren't able to find a specific compiz log, so I started it via console the output was:
[14:03:43][blq@myhost ~]$ fusion-icon

* NVIDIA on Xorg detected, exporting: __GL_YIELD=NOTHING

... executing: compiz --replace --sm-disable --ignore-desktop-hints ccp --loose-binding --indirect-rendering
fuse: failed to access mountpoint compiz: No such file or directory
compiz (cube) - Warn: Failed to load slide: freedesktop
Somehow I weren't able to get any window-decorations to work. (Emerald)

I allready tried that. I only added what was absolutely necessary to get the monitors working  ....  same problem........
I've read the NVidia wiki several times and very carefully. I went through every single step.. there is nothing more available that could solve my problem.
Thankyou very much for the responses!
