Siempre me han ido bien, aunque tengo el kernel 2.6.0-test5 con el parche para 
nvidia, pero se actualiz� algo con el apt-get upgrade y ahora despu�s de tres 
intentos me manda a la consola.
Y si intento compilar otra vez los drivers de nvidia en el kernel pues funciona 
bien, los carga a la perfecci�n y como ya he dicho cuando empez� a fallar yo no 
habia tocado nada.
Esto pone en el kdm.log respecto al fallo.
