Lately I upgraded Ubuntu from 10.10 to 11.04. It was great with a nice login background. After logging in, I found the graphics was an issue. Either the driver or the laptop was not supportive. The Laptop config is a 64 BIT, 4 GB RAM, ATI 9488 card.
Finally logged in with Ubuntu Classic, which barely gave me any designer views. Playing around with it quite a bit, I removed the entire desktop gui, landed with the terminal login.
Once you login enter gnome-terminal, then you will be taken to the terminal screen with the file menu. The advantage of this is that you could open up different terminals, the disadvantage is that, you cannot see the previous terminal when a new one is open.
Enter the following lines
sudo apt-get install ppa-purge
sudo ppa-purge ppa:gnome3-team/gnome3
Once this is done sudo reboot, should bring you back to the login window. Selecting the required username does not bring you the list ubuntu/unit2d etc. Those are all gone, when you remove the desktop-gui. This will keep you on the 11.04 update without graphics issue, and the theme of 10.10.
Some of the issues I had after going through the above was, the task bar was missing.
Add it to the startups by
Click the Add button and enter gnome-panel in the command line
Enter a name and description, just to keep you updated and reboot/logout and login.
Everything should go fine.
