OpenSUSE Hardware :: Extended Desktop - X Crashes On 11.3

I am trying to get an extended desktop (laptop monitor + extra) on my OpenSuse 11.3 system (64). I use kde 4.4.

It used to work on my OS 11.0. Here is the deal now:

- I use NVIDIA G2 driver from the OS repositiory
- laptop screen works fine, including compositing, 3D etc

I run nvidia-xconfig to generate an xconfig file. Everything still works fine (even after x reboot):

Code:

Next I login as root and open the run nvidia-setting program. There the second monitor is detected. I enable it as extended desktop and check: enable Xinerama.

I reboot.

Problems:
- compositing is off, I cannot enable it
- if I move my mouse cursor to the second screen, it only stays there for a second and vibrates enormously.
- if I use a window on the 2nd screen. X crashes

Things I can add/remove from the xorg.conf?

Now the xorg.conf is as follows:

Code:
