Unable to enable desktop-effects from the System menu saying that 3D acceleration is not running. In glxgears I'm getting about 600 - 700 fps. Running the F13 Noveau test day x86_64 LiveCD 20100412. I ran compiz --replace from the terminal and it errored out and eliminated the window decorations.

Did you install mesa-dri-drivers-experimental? Full glxinfo output, and rpm -q mesa-dri-drivers-experimental would be useful!
My mistake, I thought they would already be installed on the Noveau test day image.
You can close this it works fine, mea culpa.
