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:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 256.35  (buildmeister@builder97.nvidia.com)  Wed Jun 16 19:15:05 PDT 2010

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0"
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"
EndSection

Section "Files"
EndSection

Section "InputDevice"
    # generated from default
    Identifier     "Mouse0"
    Driver         "mouse"
    Option         "Protocol" "auto"
    Option         "Device" "/dev/psaux"
    Option         "Emulate3Buttons" "no"
    Option         "ZAxisMapping" "4 5"
EndSection

Section "InputDevice"
    # generated from default
    Identifier     "Keyboard0"
    Driver         "kbd"
EndSection

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "Unknown"
    HorizSync       28.0 - 33.0
    VertRefresh     43.0 - 72.0
    Option         "DPMS"
EndSection

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection
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

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


Now the xorg.conf is as follows:


Code:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 256.35  (abuild@nott)  Mon Jul 19 20:46:12 UTC 2010

Ok, it works if I check "twin view" instead of seperate xview". Perhaps something was bug-fixed in the meanwhile?
