Before I describe my question I want to say that I'm new to Ubuntu so if something is not clear about my question feel free to ask.
I installed a driver update for AMD. It said that I only need to restart my computer to finish the installation. After I did something else, I restarted my computer and chose Ubuntu (I have Ubuntu and Windows 7 on 1 computer thanks to the Windows Installer).
So I chose Ubuntu and then it happened.
It showed me the normal screen with "Ubuntu" in the middle of the screen. Under it were 5 orange dots. Then NOTHING happened. The only thing I could do is to shut down my computer with the button on my computer case.
Now I don't know what to do, I hope someone knows an answer to that :/
