Problem with Ubuntu Natty

[Javier Revilla]

Dear users, 

Today in the morning my Linux system was perfectly stable. I was using
the Ubuntu 10.04 LTS version. Then, I received a message inviting me to
upgrade to Ubuntu Natty. 

I committed the error to accept. And now I am stuck with an unusable
machine. I have no access to the graphic mode. So, I have to work in
text mode. I have tried re-installing the N-vidia drivers but the
problem remains. 

I am really furious at Ubuntu.I trusted them and now I am stuck with a
useless system. They should not deliver crappy software !
That is the reason I got away from Windows and embraced Linux. 

So, please, help me to get out of this situation. 
I need my machine quite urgently.

Best regards, 

Javier Revilla
