You agreed not to bump posts when you registered here.

A lack of information is very difficult to work from. If you're going to bump you could at least add more when you do. What exactly did you do?

ok sorry.
Step which I have done:

  1. update driver (I add root password , accept .. etc)
  2. after all done it ask to restart
  3. when restart I can see that screen with ubuntu and after 10 seconds it go to a black screen.

One suggestion and/or how I can access my hard disk to can back up some files and after to can install new ubuntu

if you can not see the graphical login screen, you can access the virtual terminals.
Try

control + alt + f2

and it should drop you into a non-graphical console.

Once you are logged in, post errors from

 /var/log/Xorg.0.log

I would also like you to try running

startx

from the console.

thanks for help. I solve problem. I go with my pc to a computer repariment and he solve it because saved data was very important.

May we know what was the issue and how it was solved?
It may be of some use here
