YUPPIEEEEEE !!! It works 99 % !!!!! THANKS. By "NvAGP" "0" I get the logo screen and then X starts. It took several weeks...but at the end, because OF ALL OF YOU...it works !!!
There's only 1% off which is that nvidia kernel doesn't load automatically, then I have to runlevel 3, modprobe nvidia, startx.
Well, I remember there are several other emails explaining how to solve this last issue, but I would really appreciate if you could explain to me in detail since I am newbie and haven't clearly understood what i have to do.
T H A N K S !!!!
