[Ubuntu-BD] X server corrupted

[9el]

I brought my laptop to let the seller check if it has any problem. Without
doing any good they blessed me by shutting it off by pressing the shutdown
button to terminate it quickly.And this has just brought a hell for my
Ubuntu's X-server.
It wasn't even loading to gui at first.

Nothing was possible with  Recovery Mode.

then, I did fschek from the BIOS's default.

then tried the recovery mode .. now it sounded to have fixed a bit.

Now, I get my my login screen for GUI... but when I enter password and hit
enter... it blanks the screen tries to load the X-server(desktop) but with a
flicker it comes back to login screen.

Tried with all the options available for login sessions. result, same!

I tried to connect to net with my Nokia with  Live DVD of  Intrepid Ibex...
I made it possible to connect with  wvdial  but it fails to write  at
 something folders 'pppd'  And konquerer dont get net because of the
failure.

How do you fix a corrupted XServer with the Live CD?

I have really important works on Ubuntu drives, dont have a backup computer
to work, Dont feel comfortable to work on Windows anymore. And have piled up
works to accomplish...
so I need some urgent help from you guys.
