xorg no arranca mas

[Paul Sutcliffe]

Despues estar optimizando mi nuevo ubuntu por un par de semanas, el xorg 
dejo de funcionar. Estoy usando una matrox millenium g400(dual)  en modo 
single.
He reinstalado los controladores de la pagina de matrox y he 
reconfigurado el xorg.conf con #dpgk-reconfigure xserver-xorg y nada de 
eso soluciona mi problema.

Alguna idea?

Xorg log:
