Compiz + FreeBSD8.1 + ATI + White Screen

[Ki-Hyoun Kim]

Hello,

I have tried to install Compiz on my T60 with ATI Graphic Card.  
glxinfo | grep -i render gives me

direct rendering: Yes
OpenGL renderer string: Mesa DRI R300 (RV515 7149) 20090101 x86/MMX/SSE2 TCL

3D Acceleration seems to work. I have installed the port mesa-demos,  
and the programm "gloss" works
very well.

Now, if I try to run Compiz, I do the following commands:

export LIBGL_ALWAYS_INDIRECT=1
compiz --replace --sm-disable --ignore-desktop-hints ccp &

Then, I get a white screen, but Mouse Pointer is still there. It  
seems, that the Compiz Plugin "zoom" works.

I tried to reinstall libGL, xorg-server, dri, but all the same.

Someone has an Idea? I already tried everything which was described in  
several Forums. But nothing helped. I also
activated AIGLX and the Composite Extension in xorg.conf.

Is it even possible to get Compiz work with ATI Mobility Radeon X1300?
