big compiz disaster: could use some advice

On an F9 64 bit system, I decided to try compiz because it worked so
beautifully on my Ubuntu systems.

I was testing the features, an tried the zoom thing in which you hit
the Super key and use the right mouse button to highlight an area of
the screen, and then that screen zooms to show just the selected part.
 Right after I did that, compiz stopped reacting to mouse and
keyboard, and I had to do Alt-Ctrl-Backspace to get X to restart.
Now, whenever I try to run compiz, I can use the Gnome applications
menu to choose programs, but none of them ever successfully start.
Compiz segfaults every time a program tries to start, and the segfault
kills the program too. Compiz flashes black for a moment then re-draws
the screen.   Here's what shows in /var/log/messages

Jun  6 10:02:08 pols110 kernel: compiz[5119]: segfault at 37866022b0

I see one of those messages for each program I try to start.

I rebooted the system, compiz comes back in this messed up state.

I'd like to "clear out" all of the compiz settings, and tried to do
that with the compiz settings manager, but this malfunction still
happens.  The only thing I can do is run System/Personal/Desktop
Effects and turn them off.

What do you think?

Here's how I got in this mess:

I installed these RPMS:

Jun 06 09:36:18 Installed: xorg-x11-drv-nvidia-libs-173.14.05-1.lvn9.x86_64

And used the Livna versions of the new X11 drivers

Jun 06 09:36:18 Installed: kmod-nvidia-173.14.05-3.lvn9.x86_64
Jun 06 09:36:19 Installed:
Jun 06 09:36:21 Installed: xorg-x11-drv-nvidia-173.14.05-1.lvn9.x86_64

GLX would not start because the X11 system was finding the generic
AIGLX instead of nvidia's glx, but glx does work after moving the
"wrong one" and creating a symbolic link

mv /usr/lib64/xorg/modules/extensions/
ln -sf /usr/lib64/xorg/modules/extensions/nvidia/

I'd encourage any of you compiz users to be cautious about using the
Super (Windows) key with the right mouse button, or else you might end
up in hell like me.
