a very good question...
The problem was that my system gave me an error and x11 didn't work.
The other problem is that I can't remember what text gives me.
The rest of the OS works fine, the only problems was to start de x11 system.
Well, if somebody has patient enaught to tell me how to make nv driver works after a nvidia driver's crash it will be great.
Ey! It can be an URL where they tell how to reinstall the x11 system with the old driver.
Thanks a lot and, please, xxqqme.
