Problema al activar Compiz

hola recién instale mdv 2009.1 y pues
estoy andando en el, como es mi costumbre activar los efectos 3d, me dispuse a hacer lo mismo en esta nueva de mdv, esta ves no me pidió instalar ningún paquete mas como en mdv 2009.0 y pues no me causo ninguna impresión, solo que al reiniciar el entorno no carga mas este.
desactive de nuevo los efecto y entre a la sesión sin 3d, me fui a consola y teclee compiz --replace, mi sorpresa es que se congela completamente y no tira ningún error pues queda inutilizable el sistema, esto no pasaba en mdv 2009.0

aquí una pic de la configuración del servidor gráfico

mi tarjeta de video es

VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 03)
