Several weeks ago, my computer has been death, he he. I say it was death because i couldn’t enter Gnome Display Manager (GDM) in my machine as i would like to enter. I don’t know why did this kind of annoying thing happen brutally to me. I have any kind of way to resolve my problem which is dropped me to a lonely and disappointed feeling after a proud thing Of Ubuntu. Really hard for me to think that my Ubuntu machine have to be resolved through a clean install!!!!! How can it be, I think it woudn’t be a matter if my Internet Connection is good enough. my Internet Connection isn’t sufficient to provide me the Ubuntu Update which now has been Hardy 8.0.4.1 as fast as you all could. How much time, also setting that i must do?

By The way, by the end of my searching, I found a great Post Which guide me in resolving my problem. Unfortunately i’m forget where the URL is located, but i remember the steps which guide me through. I know My Problem was because My ATI Driver so actually i want to find my way ‘home’ by resetting it using terminal. But that was a Big Lie (means Nothing’s happen!!) I cant do it!

and finally I tried this steps and works successfully!!!!

1. If you are facing your White Screen of Death, Try this Alt+Ctrl+F1, It would lead you to the tty Mode. Log in and restart by typing sudo shutdown -r now You will be restarted
2. (if you haven’t been starting your machine you may go from this point) In the login screen, click the option button which is located on 7 O’Clock direction (lower left)
3. Choose Session
4. Choose the Failsafe GNOME option and click OK
5. Now your screen is really beautiful, Isn’t it? hehe
6. Your work isnt finished yet, Go to the Application >> Add and Remove Programs
7. YOu will be escorted to the Program Package that is installed or ready to be installed in your machine (because I’m Using ATI CARD and i know the problems coming right from it) Type ATI in search bar, scroll down and uncheck the ATI binary X.Org driver (if u are using another Card, Sorry I dont recommend you to use this) Click Apply
8. Insert your Password, and Ok again
9. Once the Process finished, you may Restart your machine, and in logon screen, See the Step No. 3 Above and choose GNOME session as your default
10. You will be log in successfully to your Hardy!!

if you still have the problems, may be you should do this in the terminal (this problem maybe because of your compiz)

I hope thats Helps
