I'm trying to get Compiz (the one that came with Ubuntu 7.04) running on my laptop. My laptop uses an ATi Rage Mobility 128 M3 (16MB). I know that's pretty weak but it renders 3d screensavers OK and OpenGL is working fine. I tried the following:

adam@adam-laptop-ubuntu:~$ compiz --replace
/usr/bin/compiz.real: Root visual is not a double buffered GL visual
/usr/bin/compiz.real: Failed to manage screen: 0
/usr/bin/compiz.real: No manageable screens found on display :0.0
Window manager warning: "" found in configuration database is not a valid value for keybinding "toggle_shaded"

I'm using the r128 driver with these options:

Section "Device"
Identifier "ATI Technologies, Inc. Rage Mobility M3 AGP 2x"
Driver "r128"
BusID "PCI:1:0:0"
Option "DRI" "true"
Option "ColorTiling" "on"
Option "EnablePageFlip" "true"
Option "AccelMethod" "EXA"
Option "XAANoOffscreenPixmaps"
Option "RenderAccel" "true"
Option "AGPMode" "x"
Option "AGPFastWrite" "on"
EndSection

Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
InputDevice "Generic Keyboard"
InputDevice "Configured Mouse"
InputDevice "stylus" "SendCoreEvents"
InputDevice "cursor" "SendCoreEvents"
InputDevice "eraser" "SendCoreEvents"
InputDevice "Synaptics Touchpad"
Option "AIGLX" "true"
EndSection

Section "DRI"
Mode 0666
EndSection

Section "Extensions"
Option "Composite" "true"
EndSection

All that I can suggest is try XGL, if that doesn't work you can try this link: HOWTO: ATI Mobility XGL/Compiz Radeon [Archive] - Ubuntu Forums

Hope this Helps,
